Abstract

A perceptual model performs an analysis of a media signal (100), such as an image or audio signal. The model may be used in media signal processing applications such as digital watermarking and data compression to reduce perceptibility of changes made to code the signal. By comparing the local image strength of various directionally filtered various of the image, the model creates a directional control vector (110). The model takes into account the local contrast (106) of the image and the directional control vector to create a gain vector.
