ABSTRACT
Image compression works by identifying and eliminating redundant, or duplicated, data from a source image. There are three main sources of redundancy in image compression. The first is known as interpixel redundancy, which recognizes that pixels that are in close proximity within an image are generally related to each other. A compression technique that reduces memory by recognizing some relationship between pixels based on their proximity is an attempt to eliminate interpixel redundancy. Run length encoding, constant area coding, and JPEG encoding seek to eliminate this source of unnecessary data.
