Working with color Color images are typically represented using several ‘color planes.’ For example, an RGB color image contains a red color plane, a green color plane, and a blue color plane. When overlaid and mixed, the three planes make up the full color image. To compress a color image, the still image compression techniques…
Statistically speaking The number of bits used to represent the quantized DCT coefficients is reduced by ‘coding,’ which takes advantage of some of the statistical properties of the coefficients. After quantization, many of the DCT coefficients often – the vast majority of the high-frequency coefficients – are zero. A technique called ‘run-length coding’ takes advantage…
Secret encoders In addition to the two approaches described above, many other methods for selecting appropriate candidate motion vectors exist, including a wide variety of proprietary solutions. Most video compression standards specify only the format of the compressed video bit stream and the decoding steps and leave the encoding process undefined so that encoders can…
Digital video compression and decompression algorithms (codecs) are at the heart of many modern video products, from DVD players to multimedia jukeboxes to video-capable cell phones. Understanding the operation of video compression algorithms is essential for the developers of systems, processors, and tools that target video applications. In this article, we explain the operation and…
