Hello. I am a beginner in image forensics, could you please tell me what algorithm do you use to implement the code. It would be best with the name of the papers provided.

CAI8: https://jivp-eurasipjournals.springeropen.com/articles/10.1186/1687-5281-2014-19#Sec6

which we found via: https://pdfs.semanticscholar.org/b2f0/51dad5b03a6fe80c4faf2382668302f31b38.pdf

CAI8 is grayscale, using white gaussian noise. The previous paper suggests that a decoupled version of the Mihçak filter is possibly even better though.
