Copy-move Detection Algorithm Based on Local Derivative Patterns
Copy-move forgery is one of most frequently used types of image forgery. During copy-move process a fragment of the image is copied and pasted to another location of the same image to hide some important area of the image. The purpose of copy-move forgery detection algorithm is to identify duplicated areas in the image. This method is based on the calculating features in a sliding or an overlap...
متن کاملCopy Move Forgery Detection Using Glcm Based Statistical Features
The features Gray Level Co-occurrence Matrix (GLCM) are mostly explored in Face Recognition and CBIR. GLCM technique is explored here for Copy-Move Forgery Detection. GLCMs are extracted from all the images in the database and statistics such as contrast, correlation, homogeneity and energy are derived. These statistics form the feature vector. Support Vector Machine (SVM) is trained on all the...
متن کاملCopy-Move Forgery Detection in Digital Images by Reduced Features Ovelapping Block-Based Algorithm
Digital image forgery is one of the problems that, besides many benefits, appears with widespread use of digital images in all areas of life. Unfortunately, with rapidly developing and increasingly more powerful hardware and software, not only is digital photography manipulation for legitimate goals easier, but also for the forgery. One well-known forgery of digital images is the so-called copy...
متن کاملAn efficient algorithm for image copy-move forgery detection based on DWT and SVD
With the rapid development and popularization of Photoshop, ACDSee and other digital processing and editing software, the non-professionals can easily modify the image to achieve the purpose of beautification, spoof or malicious tampering. Digital tampering usually has ulterior motives, which would bring crisis of confidence to the credibility of media image, the authenticity of judicial eviden...
متن کاملPerformance evaluation of block-based copy- move image forgery detection algorithms
Copy-move forgery is a particular type of distortion where a part or portions of one image is/are copied to other parts of the same image. This type of manipulation is done to hide a particular part of the image or to copy one or more objects into the same image. There are several methods for detecting copy-move forgery, including block-based and key point-based methods. In this paper, a method...
