WebMay 4, 2024 · The value of any given pixel can be predicted from the values of its neighbors. The information carried by is small. Therefore the visual contribution of a single pixel to an image is redundant. Otherwise called as spatial redundant geometric redundant or interpixel redundant. Example : Run length coding 0 votes asked 0 votes WebPsycho-visual redundancy This type is due to the limitations of human eye sensitivity to visual information. It arises because the eye uses a subjective form of evaluation, characterized by its vast power for perceiving the overall image structure, but with the corresponding loss of being able to perceive each detail (pixel) separately. illegal increase in rent
