Marr Hildreth edge detector
no vote
In computer vision, mar Hildreth algorithm is a kind of digital image of edge detection, that is, continuous curve method has strong image brightness and fast change. The edge detection method of Mar Hildreth is simple and convenient. The convolution and Laplacian Gauss function can be used as the fast approximation of Gauss difference image. Then, zero cross detection filters the results to get the edge. Gaussian Laplacian image operator is sometimes called Mexican Hat wavelet due to its visual shape when turned on up down. David Marr and Alan C. Hildreth are two inventors. However, there are two main limitations. It generates a response in which the mismatched edges, the so-called & quot; pseudo edges & quot;, and the positioning errors may be severely curved edges. Today, there are many better edge detection methods, such as the canny edge detector based on local orientation maximum gradient amplitude, or the differential method based on zero cross correspondence For more details, see the article on edge detection.

Copy-Move Forgery Detectors and Ground Truth Generator
no vote
This software package contains the core components (code, some scripts) for our paper "An Evaluation of Popular Copy-Move Forgery Detection Approaches" by V. Christlein, C. Riess, J. Jordan, C. Riess and E. Angelopoulou. The software consists of a single binary. Subcommands can be passed as the first parameter to either create ground truth for Copy-Move Forgery Detection (CMFD), or to apply a CMFD detector to an image. To build the code, you require a) a recent version of OpenCV, b) a recent version of the boost library and c) cmake. The ground truth generator comes with a couple of perl scripts, which are not critical to the functionality of the software. We tested the code on a debian squeeze Li
