Laplacian Distortion Model (LDM) for Rate Control in Video Coding
Abstract. In many rate control models, a uniform weighted distortion has been assumed; that is, the DCT coefficients of the motioncompensation difference frames (residues) conform...

A Multidimensional Histogram Equalization by Fitting an Isotropic Gaussian Mixture to a Uniform Distribution
In this paper, a novel method to extend the grayscale histogram equalization (GHE) for color images in a multidimension is proposed. Unlike most current techniques, the proposed m...
