The complex wavelet Transforms CWTs are known for their excellent edge preserving together with nearly shift invariant features. They are implemented as two real DWTs connected in parallel. These two DWTs are designed such that their wavelet coeffici

This paper describes a simple fast forgery detection scheme. The proposed technique makes use of the fact that, the copied or tampered parts, will not contain the correct camera fingerprint, of the regions it copied to. The technique is based on loca
