Image Compression Study Using Lossless and Lossy Techniques

Electronics & Communication

Image compression is a type of data compression in which the real image is encoded with a few bits. The goal of picture compression is to reduce the redundancy and irrelevance of image data so that it may be recorded or sent in a useful format. As a result, picture reduction reduces network transmission time and increases transmission speed. "A picture is worth a thousand words," as the adage goes. Words are incapable of expressing what an image can say. Images are essential for representing important information and must be retained for later use or conveyed across a channel. Images must be compressed in order to make the most use of storage space and transmission speed. Picture compression is a technique for lowering the file size of an image while maintaining acceptable image quality. For a long time, image compression has been employed, and numerous techniques have been developed. The topic of picture compression as it applies to many domains of image processing is discussed in this study.
