Low-Complexity Encoder Framework for Window-Level Rate Control Optimization  
There exists a tradeoff between visual quality smoothness and buffer constraint in rate control. Thus, a window model and a window-level rate control algorithm were proposed to handle such a tradeoff ......

Perceptual video coding based on MB classification and rate-distortion optimization  
Abstract The efficiency of a video coding scheme should be defined as the video quality achieved for a given bit-rate. The quality refers here to the subjective quality perceived by the final user. Th......

Perceptual Video Coding Based on SSIM-Inspired Divisive Normalization  
We propose a perceptual video coding framework based on the divisive normalization scheme, which is found to be an effective approach to model the perceptual sensitivity of biological vision, but has ......

Sliding-Window Designs for Vertex-Based Shape Coding  
Traditionally the sliding window (SW) has been employed in vertex-based operational rate distortion (ORD) optimal shape coding algorithms to ensure consistent distortion (quality) measurement and impr......

Rate-Distortion Optimized Cross-Layer Rate Control in Wireless Video Communication  
A wireless video communication system can be designed based on the rate-distortion (R-D) criterion, i.e., minimizing the end-to-end distortion (which includes quantization distortion and transmission ......

In-Layer Multibuffer Framework for Rate-Controlled Scalable Video Coding  
Temporal scalability is supported in scalable video coding (SVC) by means of hierarchical prediction structures, where the higher layers can be ignored for frame rate reduction. Nevertheless, this kin......

gait recognition based on lower limb  
In this paper, a new approach is proposed for extracting feature from walking human based on the lower body. This approach utilized DCT to extract features followed by PCA as feature selection. Furthe......
