In the process of image processing and storage optimization, the JPEG compression ratio directly affects image quality and file size. This example demonstrates the implementation of JPEG image compression, intuitively presenting the relationship between image effects and file sizes at different compression ratios. 1. Code %% JPEG compression processing with different quality ratios im = … Read more
