Introduction
This is the web-home for GrOVis' FVV texture codecs. The FVV texture codecs utilize new combinations of known compression techniques to yield more compression out of 4D (time, camera angle, image dimensions) texture data that is commonly used in model-based FVV.

The data is meant to be used as an example for what the codecs are able to achieve.
The set consists of frame sequences rendered from 8 different camera views located in a circle around the scene. The recorded scene contains a humanoid figure, animated by motion-captured data. A shilhouette set can be extracted with an RGB != (0,0,0) test. The sequences are 465 frames long for the texdiff codec and 40 frames long for the 4dspiht codec. Each frame is saved as a 512x512 image. Some snapshots from the sequences can be seen in Figure 1.

Download
We currently only provide the files separately, from HTML pages, FTP and tar-files will follow.
A good solution for the download is to cut & paste the directory name into wget, e.g.
wget -l 1 -r http://www.mpi-sb.mpg.de/~gziegler/texfold_data/soutput_070/
Please be advised that the texdiff directories are HUGE!
