Image Retrieval Based on Bit-Plane Distribution Entropy
Based on the analysis of color histogram for image retrieval, a new descriptor, bit-plane distribution entropy (BPDE), is proposed in this paper. The image is firstly divided into ...

A New Bit-Plane Entropy Coder for Scalable Image Coding
Compression ratio and computational complexity are two major factors for a successful image coder. By exploring the Laplacian distribution of the wavelet coefficients, a new bit ...

Low-Complexity Scalable DCT Image Compression
We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but...

Analyzing Symbol and Bit Plane-Based LDPC in Distributed Video Coding
Many distributed video coders are implemented using sophisticated error correction codes that use soft information (conditional probabilities) as a priori knowledge. This a priori...

Inverse Bit Plane Decoding Order for Turbo Code Based Distributed Video Coding
For Turbo Code based Wyner-Ziv codecs, we propose to use an inverse bit plane decoding order. The investigations have shown that the knowledge about MSB's has only a marginal...
