| Abstract(in English) | In the natural visual environment, form and color seem to be statisically independent. It is therefore possible that the separation of form and color in the visual-system is based on their statistical independence. In this study we generated a set of learning samples that is the response of cones in the cone-mosaic arrangement to the natural visual environment. We then calculated the filters (receptive fields) that transform the samples to a statistically independent representation using Independent Component Analysis (ICA). In the resulting filters, there are color-opponent receptive fields with high spectral sensitivities, as well as Gabor-like receptive fields consisting of both L-and M-cones. In the former, some filters also have spatial opponency, and some don't. |
