In Section 4.2, we showed that such doubly compressed I-frames may introduceartifacts in the DCT coecients and showed how these artifacts can be quantied andestimated to detect tampering. Note also that the second and third P-frame of the rstand second GOP were, in the original sequence, in dierent GOP sequences.
