The DynTex database

The DynTex Database

The DynTex database is a diverse collection of high-quality dynamic texture videos. Currently we are finalizing the structure of the database. In the meantime, more than 650 sequences are already available for downloading.

Central to the database is the so-called golden set of high-quality dynamic texture sequences that satisfy all criteria of the acquisition protocol. This set will be further structured by its underlying physical processes, e.g turbulent motion, waving motion, discrete units etc. Additionally, they will be classified by their shot type, i.e. either as closeup (shot consisting entirely of the dynamic texture, no segmentation required), or as context (the dynamic texture is shown in its context). Next to the golden set we will offer various other sets. Examples are a collection of dynamic texture sequences recorded with a moving camera, and a collection with several dynamic textures per sequence.

Next to the basic structuring of the database, an extensive annotation effort is underway. For each sequence we will offer an XML-description characterizing both its content, as well as the context in which it was recorded.

Examples of annotation variables are: presence of disturbance, spatial and temporal regularity, texture scale.

The XML-annotations can be used for convenient selection of interesting subsets of the DynTex database.

The sequences are available in avi-files (type II) using lossless DV-compression. A free Panasonic DV codec can be downloaded here. The sequences are in color, PAL format (720 x 576, 25 fps). Next to these 'raw' sequences, processed sequences, which have been deinterlaced with a spatio-temporal median filter, are also provided. Please refer to the Download section for further details. All sequences consist of at least 250 frames. If sequences of a standard length are required, the first 250 frames of each sequence can be used. Sound is included only when relevant to the texture.

Below are ten preview samples from the DynTex database. By clicking a key frame, a DivX-compressed video of the sequence can be viewed. Note that, due to high compression, the quality of these videos is much lower than the official DynTex sequences. For downloading of the full quality videos registration is required.
