In this paper, new techniques for the DCT image coding based in pixels classifications are proposed. Two image coding approaches based on the object extraction are presented to study the effect of the object based image coding on the compression quality. Moreover, modification of the traditional JPEG method based on Region-of-interest coding is achieved. In the beginning, the image is subdivide...

This demonstration aims to present a testbed of an advanced network coding scheme, pipeline network coding, for multicast streams. Conventional network coding approaches are mostly based on a block-based coding scheme. The block-based coding scheme (batch coding scheme) introduces noticeable coding delay as well as results in discarding generations that have not enough coded packets received. T...

In this paper, we present a novel energy compaction method, the selective block reordering, which is used with SPIHT (SBR-SPIHT) coding for low rate video coding to enhance the coding efficiency for motion-compensated residuals. The inter-frame coding basically includes three major parts motion estimation, motion compensation, and motion-compensated residual coding. The motion estimation and ov...

The Block Truncation Coding (BTC) is one of the lossy image compression algorithms. In this paper, we have proposed a method called the Improved Adaptive Block Truncation Coding (IABTC) based on Adaptive Block Truncation Coding (ABTC). The feature of inter-pixel redundancy is exploited to reduce the bit-rate further by retaining the quality of the reconstructed images. The proposed method outpe...
