Texture modeling

This is an example of a Photobook search based on texture. The query image is in the upper left; the most similar images in the VisTex database are displayed in raster scan order.

VisMod texture hackers:

• Fang Liu developed the Wold texture model, which describes textures in terms of periodic, oriented, and random components.
• Martin Szummer applied autoregressive modeling in 3D to synthesize and classify temporal textures, like smoke, rustling leaves, and boiling water.
• I implemented some models from the literature, including an awesome 2D autoregressive model (a rip-off of Fang's code), spatial gray-level cooccurrence matrix features, and the coarseness, contrast, and directionality features used in QBIC.
