MIJ2K: Enhanced video transmission based on conditional replenishment of JPEG2000 tiles with motion compensation

Transmitting video surveillance sequences based on JPEG 2000 conditional replenishment

In many video surveillance applications, images are stored locally and are likely to be accessed remotely and possibly interactively upon user request. In such context, the JPEG 2000 still image compression format is attractive because it provides high coding efficiency, while supporting a highly flexible access to each individual image, in terms of spatial location, quality level, as well as r...

Motion-JPEG2000 Stream Scaling for Multi-Resolution Video Transmission

In this paper, we present a real-time video system for the transmission of Motion-JPEG2000 codestreams with multiple resolutions. To achieve this multi-resolution video in real-time, a software tool, named ‘stream scaler’, was newly developed. It directly looks at each packet’s location in a codestream before deciding whether it is accepted as a new packet for a scaled codestream. The SOP marke...

Advantages of motion-JPEG2000 in video processing

Lifting Based Video Coding Using Motion Compensation

This study introduces a video compression method that uses spatio – temporal lifting based algorithms to compress the video signals. The temporal correlation of consecutive frames causes temporal redundancies which are subject to lifting-like motion predictive compression. Moreover, the spatial correlation between neighbouring pixels of the same frame is subject to intra-frame wavelet compressi...

Motion compensation based on tangent distance prediction for video compression

We present, in this article, a new algorithm for motion compensation that uses a motion estimation method based on tangent distance. The method is compared with a BlockMatching based approach in various common situations. Whereas Block-Matching algorithms usually only predict positions of blocks over time, our method also predicts the evolution of pixels into these blocks. The prediction error ...
