Abstract

The interaction between the mechanisms of local and global image analysis at the level of the magnocellular and parvocellular channels of the human visual system was studied. Using wavelet filtering, the spatial frequency composition of texts presented to observers was varied. It was shown that gradual blurring of texts via wavelet filtering interferes with the work of the parvocellular system but simultaneously increases the contribution of the magnocellular system during reading. With an increase in the wavelet element scale, the parvocellular system receives insufficient information for effective work, and in this situation the magnocellular system determines the strategy of eye movements. In addition, the necessary frequency range that ensures the functioning of the reading process is provided.
