Texture discrimination and binding by a modified energy model

The model presented shows how textured regions can be discriminated and textured surface created by the visual cortex. The model addresses two major processes: texture segmentation and texture binding. Textures are detected by using a version of the energy model of J. R. Bergen and E. H. Adelson (1988) and J. R. Bergen and M. S. Landy (1991), which was modified to include ON and OFF center cells, and units selective for line endings. A novel neural mechanism is described for binding a texture pattern together. Simulation results demonstrated the ability of the networks to segment and bind a well-known texture pattern.
