how do i write a code to detect double quantization effect with openCV like this article "Detecting Doctored JPEG Images Via DCT Coefficient Analysis"

推荐答案

可能是最好的地方开始是与知道文章的人 - 作者。如果您在此处找到了该文章，那么该文章底部会显示一条新邮件按钮，这会将电子邮件发送给作者。然后他们会被告知你希望与他们交谈。

在这里发布这个依赖于他们匆匆而过并意识到这是为了他们。

Probably the best place to start is with someone who knows the article well - the author. If you found the article here, then there is a "new message" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.
