Principle of a parallel vision system adapted to textures. A theoretical solution for selecting visual filters

摘要

A number of methods for classifying textures and for segmentation of textured images make use of multichannel filtering techniques because of their computational simplicity. On the other hand, biological experiments have shown the existence and the proper- Ties of visual channels and make it possible for us to select the "best" filter bank. In A performing artificial vision system, three important problems are to be solved: the Rigorous sampling of the spatial frequencies, the scale related problem and parallel pro- Cessing.
