Claim:
1. A method for estimating video quality, comprising: accessing image data having at least one image region; decomposing the image region into a structure component and a texture component; determining an edge strength for the structure component of the image region; determining a texture masking weight in response to the edge strength, wherein the texture masking weight is set such that no texture masking property is used when the edge strength exceeds a threshold, wherein the texture masking weight is determined responsive to a texture strength for the texture component of the image region when the edge strength does not exceed the threshold, and wherein the texture masking weight is set such that no texture masking property is used when the texture strength of the texture component of the image region does not exceed a second threshold; and determining a quality metric in response to a local distortion of the image region weighted by the texture masking weight.
