I am trying to get the compression rate of two images in Error Level Analysis form. One image is manipulated and the other is not.

I want to get the compression level to use it as a split feature in random forests. If the compression is high then it is manipulated.

Here is the manipulated image in ELA

Here is the non-manipulated image in ELA

non-manipulated image in ELA

Thank you.
