N2 - We describe a framework for decomposing the distortion between two images into a linear combination of components. Unlike conventional linear bases such as those in Fourier or wavelet decompositions, a subset of the components in our representation are not fixed, but are adaptively computed from the input images. We show that this framework is a generalization of a number of existing image comparison approaches. As an example of a specific implementation, we select the components based on the structural similarity principle, separating the overall image distortions into non-structural distortions (those that do not change the structures of the objects in the scene) and the remaining structural distortions. We demonstrate that the resulting measure is effective in predicting image distortions as perceived by human observers.
