Is pattern masking predicted by the cross-correlation between signal and mask?

abstract：:Recent neurological studies of selective impairments in first and second-order motion processing are of considerable relevance in elucidating the mechanisms of motion perception in normal human observers. We examine the stimuli which have been used to assess first and second-order motion processing capabilities in cli...
