MODULAR MODEL (Glezer, 1995)

A visual cortex module is a column of units whose RFs are Gabors with the same size and location, but different orientations. Physiological data (Glezer et al., 1989) show the number of cycles in simple cell RFs varies from 1 to 4. For the module units, the number of cycles in the RF are from the sequence: 1.00, 1.41, 2.00, 2.90, 4.15. The visual cortex modules thus perform a piecewise Fourier analysis of the image projected at the central linear zone of the module RF.

Since the presentation of more than one reference during a session distorts the perception of image equality, we supposed that the weights of modules which correspond to sizes near the references increase, thereby distorting the size perception at the boundaries of the range of sizes used.
