I have a question about impact of different attack like jpeg, Gaussian noise,... on different coefficients of wavelet output. for example we know jpeg can destroy high frequency part of DCT but I want to know these attacks how can affect on wavelet output like HH, LH, HL channels. can you help me or introduce document which explain it? thanks in advance.
