For the JPEG domain, decompress images to the spatial domain without rounding to integers and save them as '.mat' files with variable name "im".
I don't know how to convert a JPEG domain image to a spatial domain.Could you tell me how to solve this problem

对于JPEG域,将图像解压缩到空间域而不舍入为整数,并将其另存为变量名称为“ im”的“ .mat”文件。
我不知道如何将JPEG域图像转换为空间域。能否告诉我如何解决此问题

请问你知道如何转变了吗,是简单的使用python将jpg图像另存为mat吗?这个变量名称im我没有明白

我用matlab 每个.mat文件的变量名为im,可以进行训练。 但是测试集的路径为什么还要区分cover和stego,为什么不是直接对一堆图片进行检测哪些有隐写,哪些没有隐写呢。这难道不是二分类么
