Selected WWW pages from the original VDP project site (the Internet connection is required to explore this site).

• Cortex transform. Visualization of the spatial frequency and orientation channels decomposition of an image processed by the amplitude-nonlinearity and CSF.
• VDP-based prediction of the detection threshold elevation resulting from masking.
• Various CSF models.
• Cortex transfrom vs.  Burt channel decomposition methods.
• Local vs. global contrast.
• Perceived shadows quality vs. masking by texture.
• Texture pattern size: Tiles, Carpet1, Carpet2.
• Texture orientation.
• Perceived shadows quality vs. observation distance.
• Perceived shadows quality vs. solution convergence.
• HTML forms for experimental validation of the VDP.
• Stopping conditions for global illumination computation.
