jpeg_toolbox是一个用于处理JPEG图像的工具箱。

简介：
This collection of software utilities incorporates Matlab procedures designed to handle and modify JPEG image files. Although Matlabs’ integrated IMREAD and IMWRITE functions offer fundamental conversion capabilities between JPEG files and image data arrays, they lack the ability to access the granular specifics inherent within a JPEG image, including the crucial JPEG coefficients and the essential quantization tables.
