Semi-Fuzzy Rate Controller for Variable Bit Rate Video
A novel semi-fuzzy (SF) rate control algorithm (RCA) for variable bit rate (VBR) video applications is proposed. The proposed RCA is optimized to provide high quality compressed vi...

Macroblock-level Reduced Resolution Video Coding Allowing Adaptive DCT Coefficients Selection
—Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampl...

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...
