The method of pixel block image quality control calculates the mean vector speed of the image (A) between two images. Discrimination of luminance components differences is carried out between different nearby pixels (B) and adjacent groups. The coefficient of visibility of a current image pair is calculated following psycho visual rules to ascertain the effect of the fault contour (C).
Digital image quality control contour fault viewing technique having two image vector speed calculation and adjacent/nearby pixel comparison with visibility component output relative psychovisual rules.
