Independent Component Filters of Natural Images Compared with Simple Cells in Primary Visual Cortex
Properties of the receptive fields of simple cells in macaque cortex were compared with properties of independent component filters generated by independent component analysis (ICA) on a large set of natural images. Histograms of spatial frequency bandwidth, orientation tuning bandwidth, length and aspect ratio of the receptive fields match well. This indicates that simple cells are well tuned ...

متن کاملIndependent component analysis of natural image sequences yields spatio-temporal filters similar to simple cells in primary visual cortex.
Simple cells in the primary visual cortex process incoming visual information with receptive fields localized in space and time, bandpass in spatial and temporal frequency, tuned in orientation, and commonly selective for the direction of movement. It is shown that performing independent component analysis (ICA) on video sequences of natural scenes produces results with qualitatively similar sp...
