Compliant Interframe Coding for Motion-JPEG2000
This publication proposes a strategy to enhance the compression performance of Motion-JPEG2000 by the reduction of interframe redundancies. This is achieved by a new frame structure allowing to remove redundancies and to reconstruct the original stream without loss. The introduced advancement is able to increase the compression e ciency and keeps other bene cial property of the traditional codec, as, highquality frame-wise access and scalability. All of the required operations are accomplished in JPEG2000 domain by examining and handling still encoded contents. Thus, the approach requires little computing power. Our results demonstrate that the strategy is at least a e cient as the original codec even for less suited video contents.
Ef cient image sequence coding exploits both intraand interframe correlations. SPIHT is ef cient in intra-frame decorrelation for still images. Based on SPIHT, differential-SPIHT removes inter-frame redundancy by reusing the signi cance map of a SPIHT coded frame. The motion differential SPIHT (MD-SPIHT) automatically decides the coding methods for each frame, according to the inter-frame corre...متن کامل
In this paper, we analyze the performance of Motion JPEG2000 for wireless applications. This new standard is based on intra-frame wavelet coding. Motion JPEG2000 is offering a number of very compelling advantages when compared to state-of-the-art MPEG-4 video coding. Wavelet coding achieves very high coding efficiency. Furthermore, because frames are intra coded, it is very error-resilient. Fin...متن کامل
Efficient image sequence coding exploits both intraand inter-frame correlations. Set partition coding (SPC) is efficient in intra-frame de-correlation for still images. Based on SPC, a novel image sequence coding system, called motion differential SPC (M-D-SPC), is presented in this paper. It removes inter-frame redundancy by re-using the significance map of a previously SPC coded frame. Every ...متن کامل
We discuss the possibilities and limitations of a scalable video codec based on JPEG2000. We give a review of wavelet-based motion-compensated temporal filtering (MCTF) and discuss how JPEG2000 components can be used for coding temporal subbands and motion data. At the example of a simple implementation that uses as many ingredients from JPEG2000 as possible, we discuss some issues in coding tr...متن کامل
This paper presents a new lossless interframe coding scheme for Magnetic Resonance (MR) images. The existing schemes, like block matching method and uniform meshbased scheme, are inadeqaute to model the motion field of MR sequence. The above schemes use uniform mesh elements which may comprise multiple motions. We propose a scheme consisting of (a) content-based mesh generation (b) forward moti...متن کامل
