Note: 1 inch = 25.4mm From the information theory perspective, compression removes redundancy in information, that is, retaining uncertain information and removing definite information (which can be inferred ), that is to say, a description closer to the essence of information is used to replace the original redundant description. CompressionThere are two types: lossless compression (reversible) and lossy
