Histogram analysis for image compression
WebbImage compression is a type of data compression in which the original image is encoded with a small number of bits. The goal of picture compression is to eliminate image redundancy and store or transfer data in a more efficient manner. The block diagram of the generic image storage system is shown in Figure 1.1.
