Image Classification Using Spatial Pyramid Coding and Visual Word Reweighting
The ignorance on spatial information and semantics of visual words becomes main obstacles in the bag-of-visual-words (BoW) method for image classification. To address the obstacles...

Adaptive Directional Wavelet Transform Using Pre-directional Filtering
This paper proposes a computationally efficient approach of adaptive directional wavelet transform (AD WT). The AD WT is based on lifting implementation of WT, and it is able to t...

Video coding with MC-EZBC and redundant-wavelet multihypothesis
Motion compensation with redundant-wavelet multihypothesis, in which multiple predictions that are diverse in transform phase contribute to a single motion estimate, is deployed i...

Disparity dependent segmentation based stereo image coding
In this paper, we propose a novel rate-distortion (R-D) optimized disparity based coding scheme for stereo images. This new scheme efficiently integrates the coding of the dispari...

Embedded image coding with context partitioning and quantization
As a key part of universal source coding, context quantization is very important for improving compression performance. However, in most existing methods, the quantizer is trained...
