This report extends MITRE's Adaptive Wavelet Image Compression (AWIC) algorithm to video compression. The resulting software, called AWIC V, uses AWIC to compress each frame of a video stream followed by a lossless motion compensation using the low-pass band of the compressed frames as reference. In practice, motion compensation adds little to the overall performance, except for possibly some g...

In this study, we investigate a variable-resolution approach to video compression based on Conditional Random Field and statistical conditional sampling in order to further improve compression rate while maintaining high-quality video. In the proposed approach, representative key-frames within a video shot are identified and stored at full resolution. The remaining frames within the video shot ...

This paper discusses current video compression techniques and presents an overview of the existing video compression standards and standards to be. The standards discussed here are standards defined by dedicated committees as well as de facto standards.

Surveillance videos are becoming immensely popular nowadays due to the increasing usage of surveillance systems in various places around the world. In such applications, cameras capture and record information over long durations of time, which result in large quantities of data, necessitating specialized compression techniques. Conventional video compression algorithms are not sufficient and ef...

Technological developments in the networking technology and the computers make use of video possible. Storing and transmitting uncompressed raw video is not a good idea, it requires large storage space and bandwidth. Special algorithms which take the characteristics of the video into account can compress the video with high compression ratio. In this paper I will give a overview of the standard...

We present a novel approach to compression of video frames based on the foveation behavior of the human visual system (HSV). Eye fixations on a video frame, as depicted by eye-gaze trace data, define an imaginary region of interest. The perceived resolution of the frame by the human eye depends totally on this eye-gaze (fixation) point. The resolution, then, decreases dramatically with the dist...

| Sequences of digital video images typically require vast amounts of electronic memory for storage, and occupy much bandwidth during transmission. Widely used image and video compression standards, such as JPEG and MPEG, use the two-dimensional Discrete Cosine Transform (DCT) to achieve near-optimal compression of individual frames. This is done by decomposing the the frames into components of...

Over the past decades, digital video compression technologies have become an integral part of the way we create, communicate and consume visual information. Digital video communication can be found today in many application sceneries such as broadcast services over satellite and terrestrial channels, digital video storage, wires and wireless conversational services and etc. The data quantity is...

The coding method in MPEG-4 for interlaced-video is introduced in this paper. Such a method is an extension of MPEG-2 interlaced coding tools to allow compression of arbitrarily-shaped interlaced-video. The new textureand-shape coding tools discussed here for arbitrarily-shaped interlaced-video provide good compression performance. It is demonstrated here that these interlaced tools improve the...

Preface In the past nine months, I carried out my the final year project of KTH international master's in SoC (System-on-Chip) at NXP Semiconductors Research (NXP), the Netherlands. Thanks to my supervisors, Prof. Axel Jantsch in KTH and Senior Scientist Tomas Henriksson in NXP. Also thanks to Pieter van der Wolf and Bram Riemens in NXP. During my internship they gave me a lot of help on the te...
