在图像处理实验中,有时需要对图像进行精确质量因子的JPEG压缩,而photoshop和一般的图像处理软件并不具备,本程序利用matlab实现该功能,并支持批处理(将待处理图像放入src文件夹,dst文件夹为输出)(In image processing experiments, sometimes the need for accurate image quality factor of JPEG compression, and photoshop and general image processing software does not have this program using matlab realize this function, and supports batch processing (image to be processed into the src folder, dst folder for output))
