Embedded coring in MPEG video compression
Coring is a well-known technique for removing noise from images. The mechanism of coring consists of transforming a noise-degraded image into a frequency-domain representation, followed by a reduction of the image transform coefficients by a (nonlinear) coring function. After inverse transforming the cored coefficients, the noise-reduced image is obtained. In this paper, we show that coring can...
متن کاملMPEG Video Compression Basics
Video signals differ from image signals in several important characteristics. Of course the most important difference is that video signals have a camera frame rate of anywhere from 15 to 60 frames/s, which provides the illusion of smooth motion in the displayed signal. Another difference between images and video is the ability to exploit temporal redundancy as well as spatial redundancy in des...
متن کاملVIDEO COMPRESSION: The MPEG Standards
In order to ensure compatibility among video codecs from different manufacturers and applications and to simplify the development of new applications, intensive efforts have been undertaken in recent years to define digital video standards. These standards were the result of joint development efforts of video and audio compression as well as other system aspects required to support all the appl...
متن کاملAn Introduction to MPEG Video Compression
MPEG video compression is used in many current and emerging products. It is at the heart of digital television set-top boxes, DSS, HDTV decoders, DVD players, video conferencing, Internet video, and other applications. These applications benefit from video compression in the fact that they may require less storage space for archived video information, less bandwidth for the transmission of the ...
متن کاملbit - rate MPEG - 2 video compression
Most real-time MPEG-2 encoders are designed to perform in a constant-bit-rate (CBR) mode, in which buffer constraints are imposed to circumvent large deviations from a desired rate at any instant in time. Although such streams are generally good-quality sequences, certain types of operations or environments call for a more efficient real-time CBR encoder. The first part of the paper describes h...
