In recent years it has become clear that linear filtering does not hold all of answers, and new solutions are becoming available through the use of non-linear techniques. For instance, while edge blurring associated with linear filters is offensive to the human eye, non-linear techniques, such as median filtering, preserve edges while smoothing other areas. The ESPRIT 7130 basic research project into RNon linear and adaptive techniques in digital image processing, analysis and computer vision (NAT)S aims to draw together, as far as possible, diverse results from non- linear processing into a unified area of theory. The tools which can be used in linear theory such as the Fourier and Laplace transforms, impulse and frequency responses are all well established but do not hold in the case of non-linear filters as the superposition assumptions of each are violated. New superposition theories are sought which are valid for non-linear filters. One such tool is the threshold decomposition property which is valid for classes of both order statistic and morphological filters. This five day course aims to bring the attendee up-to-date in non-linear techniques and solutions for image processing. It will provide hands-on sessions, as well as comprehensive course notes. The instructors are drawn from the main NAT partners and are all active in these research areas. Whilst the course will cover the emerging theories it will also contain a session on the parallel implementation aspects of the course. The application of this work is very broad including such diverse areas as biomedical image processing, sensor fusion, high definition TV and industrial flame control. The NAT consortium has been working on these applications, and a key aim of this course is to impact this experience and expertise to the attendees. If you are involved in image processing research then this course should prove to be an invaluable addition to your knowledge base. The course has been endorsed by: British Telecom plc; British Gas plc; Sun Microsystems (UK) Limited; Scottish Enterprise; British Machine Vision Association (Scotland); DSP Technical Committee of IEEE CAS Society. ******* Recent Advances in Image Processing 6-10 June 1994: Glasgow, Scotland, UK REGISTRATION FORM Name .............................................................

First IEEE international conference on image processing: update ------------------------------------------------------------------------------- From: icip@pine.ece.utexas.edu (International Conf on Image Processing Mail Box) FIRST IEEE INTERNATIONAL CONFERENCE ON IMAGE PROCESSING November 13-16, 1994 Austin Convention Center, Austin, Texas, USA Dear Colleague: We are happy to be able to inform you of current events involving ICIP-94. First, we are developing an exciting program that will include: 4 Tutorials: M. Vetterli & J. Kovacevic on Wavelets B. Girod on Compression of Still and Moving Images R. Haralick on Mathematical Morphology R. Blahut on Imaging Systems 3 Plenary Talks: Paul Lauterbaur, Univ. of Illinois at Urbana-Champaign Peter Burt, Sarnoff Labs Gary Starkweather, Apple Computer 6 Special Sessions: Image Processing Education (R. Bamberger & J. Cozzens) Signal Processing in Magnetic Resonance Imaging (Z. Liang) Mathematical Morphology (D. Schonfeld & I. Pitas) Nonlinear Dynamics in Image Processing (G. Sapiro & A. Tannenbaum) Imaging Modalities (J. Quistgaard) Electronic Imaging (C. Bouman and J. Allebach) In addition there will be an exciting Product Exhibition featuring over 25 booths displaying today's state-of-the-art commercial image processing hardware, software, and accessories. This will be held in the Exhibit Hall at the Austin Convention Center. As of February 23, 1994 (today) we have recieved over 700 paper submissions to ICIP-94 - attesting to the excitement that the conference has engendered in the image processing community. And certainly, presenting a challenge to the ICIP-94 Technical Program Committee to conduct a timely review process! Nevertheless, it is necessary to announce an EXTENDED DUE DATE for further submissions to ICIP-94. This is made necessary because of an error by IEEE Publishing - the ICIP Call for Papers was inadvertently omitted from the recent issues of the IEEE Transactions on Image Processing and the IEEE Transactions on Signal Processing. Since these are our primary means of communicating with the members of the IEEE Signal Processing Society, we felt it necessary to give all SP Society members a chance to participate by advertising in the next available issue - with an extended due date: EXTENDED ICIP-94 SUBMISSION DEADLINE: MARCH 15, 1994. Naturally, this applies to everyone. If you would like another copy of the electronic version of the ICIP-94 Call for Papers, please let us know at icip@pine.ece.utexas.edu with the message "CFP Please." Please note that the above extended deadline is STRICT. Submissions that are postmarked later than March 15, 1994 will not be accepted. This is necessary to ensure a fluid review process. We look forward to seeing you in Austin!

Question: aliasing ------------------------------------------------------------------------------- From: tmedl@mbvlab.wpafb.af.mil Question: Since morphological operators are non-linear operators, does one have to worry about aliasing the image? Thanks for all your help. Tom Medl ------------------------------------------------------------------------------- 5. Question: rotated structuring element ------------------------------------------------------------------------------- From: pff@raster.Kodak.COM I've been reading about morphology, and have been having problems understanding why the structuring element is rotated around the origin for erosion. Two of the references I have been looking at are: Image Analysis and Mathematical Morphology (Volume 1) by Jean Serra An Introduction to Morphological Image Processing by Edward R. Dougherty In both of these cases, they go through the definition of binary erosion, but they seem to pass by the reasoning behind using the rotated structuring element without much explanation. I was hoping that someone could point me towards a more in-depth explanation. Should I look to some of the references towards Minkowski Algebra to find out the 'why' behind the use of the rotated structuring element in erosion? Also, as a related question, why isn't the structuring element rotated for dilation also? Thanks in advance.

Morphology software ------------------------------------------------------------------------------- From: rap2@vuse.vanderbilt.edu (Alan Peters) Release announcement for version 4.1 of Alan Peters's morphology software. Created 19 July 1993. See the end of this announcement for a list of changes. *** IMPORTANT *** If you are currently using this software, or if after reading this, you download and use this software, kindly send me an e-mail note. I want to compile a list of users so I may keep you informed of any changes, additions, or bug-fixes. Thanks! ======================================================================= Software for 2D and 3D Mathematical Morphology written by Richard Alan Peters II Assistant Professor of Electrical Engineering Vanderbilt University School of Engineering Nashville, TN 37235 (615) 322-7924 rap2@vuse.vanderbilt.edu Mathematical morphology is a powerful tool for image analysis and enhancement. Morphological operators are shape-dependent, nonlinear image transforms such as erosion, dilation, opening, closing, and rank filters. The mathematical operators are defined in n dimensions so it is possible to create programs that will operate on 1D signals, 2D images, or 3D datasets using exactly the same concepts. As operators on 2D binary images, mathematical morphology is well known; much software is available which performs binary morphology. However, the true power in morphology lies in its ability to transform grayscale 2D pixel images and 3D voxel datasets. Software for these operations is less common. This is a morphological software package written under the auspices of the US Airforce Office of Scientific Research at Arnold Airforce Base, Tullahoma, TN during the 1991 Summer Faculty Research program. Subsequently, it has been in continual use and has undergone numerous enhancements. The software includes a 2D image morphology program, a 3D voxel image morphology program, a program for enhancement and noise reduction of 2D images, and related support routines for image arithmetic and logical operations. There are standard unix man pages for all programs. These programs will perform many -- if not all -- of the possible morphological operations on both binary and grayscale images. They include erosion, dilation, opening, closing, rank filters, LUM filters, etc. The 3D image program is ideally suited for the processing of image time-sequences as well as true 3D data. The programs provide many of the commonly used features automatically (such as disk shaped or ellipsoidal structuring elements) or permit the user to customize the operation to fit an application. The user programs operate on Sun rasterfiles. However, the main morphological routines are c-code subroutines. These are independent of specific file formats, so a users can easily write an interface program to operate on other file formats. The software was written on Sun Sparcstations under SunOS Release 4.1.3. However, I used no indigenous libraries other than libm.a. The user interface is of the standard csh command-line variety. This should make porting to other unix platforms trivial (Yeah, right!). I know of one person who ported the program to a PC using Borland C. Apparently, it was not too terribly difficult. This software is freely redistributable, providing I and my school get appropriate credit where due. I hereby grant permission to post the software at any netsite or BBS's, providing, of course, that I get authorship credit, etc. I am not in a position to actively support development of this software. Nor do I have a lot of time to answer questions about it, although I'll make every attempt to do so. The software was used by a dozen grad students in a seminar class this spring; so I'm reasonably sure the most egregious bugs have been squashed. Please do report any bugs to me, though. I'll do what I can to fix them. Also, if you download this software and actually use it, please drop me an e-mail note. I'll then keep you informed of any changes, bug fixes, etc. Enjoy! -Alan. ======================================================================= The following are the programs included in version 4.1 of the mathematical morphology software: Morphology programs: morph - 2D mathematical morphology. It performs erosion, dilation opening, closing, rank, tophat, bothat, LUM, LUM smoothing, LUM sharpening, and binary shape removal. It does both binary and grayscale operations as either set or function operations. morph3d - 3D mathematical morphology. It performs erosion, dilation opening, closing, rank, maxmin, minmax, LUM, LUM smoothing, LUM sharpening, and binary shape removal. It does both binary and grayscale operations as either set or function operations. mclean - 2D morphological noise reduction program that uses morphological size distributions for grayscale image noise reduction while preserving small features. Arithmetic programs: andimg - Perform a pixelwise logical AND of two images. avg3d - Performs a pixelwise running nth order combination on an image time-sequence. Combination types are average, minimum, maximum, median, rank, ordinary linear combination, and rank-ordered linear combination. comb3d - Performs a pixelwise frame-by-frame combination of n image time-sequences or 3D voxel images. Combination types are average, minimum, maximum, median, rank, ordinary linear combination, and rank-ordered linear combination. combimg - Performs a pixelwise combination of n images. Combination types are average, minimum, maximum, median, rank, ordinary linear combination, and rank-ordered linear combination. This particular program was designed specifically to implement the Song-Delp generalized morphological filters. See, Song, J., and E. J. Delp, "A study of the generalized morphological filter,'' submitted to Circuits, Systems, and Signal Processing, 1990. linco - Performs a linear combination of two byte images. Performs 6 different kinds of output scaling: (1) clip if out of bounds, (2) linear compress if out-of-bounds, (3) linear scale of min,max to black,white, (4) scale up if max < white, (5) scale down if min > black, (6) affine scaling using user parameters. It can also be used to scale single images. maximg - Perform a pixelwise maximum of two images. minimg - Perform a pixelwise minimum of two images. orimg - Perform a pixelwise logical OR of two images. support - returns the number of active pixels in a given structuring element. This is very useful for setting rank and LUM filter parameters in morph or morph3d. Rasterfile programs: rasremap - Creates a grayscale rasterfile from an arbitrary 8-bit rasterfile. Causes pixels to at once reference grayscale colormap and reflect true grayscale value. ras2raw - Creates a byte array from an 8-bit rasterfile. raw2ras - Creates an 8-bit rasterfile from a byte array.

Some math libs don't contain log2. (2) morph3d_sub was rewritten to permit SE depths of 1 and 2 to run correctly. (3) program "support" was added to the util directory. It calculates the number of active pixels in a structuring element. This is useful for setting rank or LUM parameters in either morph or morph3d. version 4.0 changes (1) The 'auto' SE flag now makes SE's with even dimensions. e.g. 2x2 (2) The rasterio utilities (in morph/utils) were rewritten to properly process images with an odd number of pixels per row. Also, OpenFile now decompresses unix-compressed (*.Z) rasterfiles. (3) Three new rank-order dependent filters were added, LUMFilt, LUMSmooth, and LUMSharp. LUMfilt is the lower-upper-middle filter as defined by Hardie, R. C., and C. G. Boncelet, "LUM filters: A class of rank-order-based filters for smoothing and sharpening," IEEE Trans. Signal Processing, vol. SP-41, No. 3, March 1993. LUMSMO is the LUM smoothing filter defined therein, and LUMSHA is the LUM sharpening filter. These filters compare the center pixel in a neighborhood defined by an SE to upper and lower order statistics in the neighborhood. Depending on the ordering either the center pixel or one of the order stats is output. (4) The 3D rankfilter now agrees with the 2D that rank == 1 == max (or dilate) and rank == support-of-structuring-elment == min (erode). ------------------------------------------------------------------------------- 7. New journal for image processing and machine vision ------------------------------------------------------------------------------- From: J.Illingworth@ee.surrey.ac.uk The IEE (Institution of Electrical Engineers) in the U.K. has re-organised its Proceedings topics and February 1994 launched a new journal title called ************************* VISION, IMAGE AND SIGNAL PROCESSING ************************* The joint Honorary Editors will be: Professor Peter Grant, Dr John Illingworth Signal Processing Group, Vision, Speech and Signal Proc Group Dept of Electrical Engineering Dept of Electronics and Electrical Eng., University of Edinburgh, University of Surrey. Edinburgh. Scotland Guildford U.K. This journal encompasses image and signal processing in its widest sense. Image processing techniques covering sampling, enhancement, restoration, segmentation, texture, motion and shape analysis are appropriate for the journal. It also covers source coding techniques which are used in image coding; for example vector quantisation, transform and sub-band techniques, motion compensation, standards and 3D-modelling for bit rate reduction in single images or image sequences. Advances in the field of speech analysis, coding, recognition and synthesis are appropriate for the journal. Signal processing includes algorithm advances in single and multi-dimensional recursive and non-recursive digital filters and multirate filterbanks; signal transformation techniques; classical, parametric and higher order spectral analysis; system modelling and adaptiveidentification techniques. Papers on novel algorithms for image and signal theory and processing together with review and tutorial papers on the above topics will be welcomed by the Honorary Editors. Papers having a practical relevence and dealing with application of these concepts are particularly encouraged. To submit a paper send 5 copies of a manuscript of approximately 12 to 16 double spaced A4 pages (or 3000 words) plus 10 to 14 illustrations to: The Managing Editor: IEE Proceedings, Institution of Electrical Engineers Michael Faraday House Six Hills Way Stevenage Herts SG1 2AY United Kingdom Longer papers will be considered if they are of exceptional merit. The journal aims to provide a rapid response to authors with 90% of all manuscripts dealt with in less than 6 months. Fuller details of the guide to authors can be found in the current IEE Proceedings parts. Dr. J. Illingworth, | Phone: (0483) 259835 V.S.S.P.

New book on multi-scale representation of image data ------------------------------------------------------------------------------- From: Tony.Lindeberg@bion.kth.se SCALE-SPACE THEORY IN COMPUTER VISION by Tony Lindeberg, Royal Institute of Technology, Stockholm, Sweden @book{Lin94-book, author = "T. Lindeberg", title = "Scale-Space Theory in Computer Vision", publisher = "Kluwer Academic Publishers", series = "Kluwer International Series in Engineering and Computer Science", year = 1994, note = "ISBN 0-7923-9418-6" } This book deals with the scale-space primal sketch, an approach which is closely related to notions in mathematical morphology. Basically, the first step in the definition of the scale-space primal sketch is based on a watershed analogy. The corresponding representation that then arises (called grey-level blob tree) is then embedded in scale-space to give descriptors much more robust to noise. The complete table of contents, foreword, preface, and abstract are available by anonymous ftp from world.std.com (192.74.137.5) (file ftp/Kluwer/book/scale_space). ------------------------------------------------------------------------------- 9.
