- W3198310132 abstract "Even though many image tamper detection methods already reported in the literature, still there is a need for developing optimized tamper detection approach due to challenges in the existing methods. This article discusses various image transformation techniques, their applications and limitations. A new block based approach is also introduced in this article. Primary objective of this method is to exactly detect and locate very small and multiple tampered regions even the tampered regions are flipped, enhanced or retouched. The proposed method works better than PCA and DCT based method and overcome the pitfalls in Exhaustive search and Autocorrelation methods which compare every image segment with all other image segment to identify similar region in an image." @default.
