In this paper, we have come up with a forensics algorithm based on adjacent pixels and multivariate coding. In the proposed method, the adjacent pixels with four directions are computed with center pixel to ferret out the overshoot artifacts caused by weak sharpening. A large number of experimental results of sharpened image detection show that the proposed method has excellent accuracy and adaptability, especially for underwater image sharpening detection.
