A Fast Keypoint Based Hybrid Method for Copy Move Forgery Detection
Copy move forgery detection in digital images has become a very popular research topic in the area of image forensics. Due to the availability of sophisticated image editing tools and ever increasing hardware capabilities, it has become an easy task to manipulate the digital images. Passive forgery detection techniques are more relevant as they can be applied without the prior information about...
متن کاملFast Copy-Move Forgery Detection
This paper proposes a method for detecting copy-move forgery over images tampered by copy-move. To detect such forgeries, the given image is divided into overlapping blocks of equal size, feature for each block is then extracted and represented as a vector, all the extracted feature vectors are then sorted using the radix sort. The difference (shift vector) of the positions of every pair of adj...
متن کاملA Non-intrusive Method for Copy-Move Forgery Detection
The issue of verifying the authenticity and integrity of digital images is becoming increasingly important. Copy-move forgery is one type of image tempering that is commonly used for manipulating digital content; in this case, some part of an image is copied and pasted on another region of the image. Using a non-intrusive approach to solve this problem is becoming attractive because it does not...
متن کاملAn Efficient Method for Copy-Move Forgery Detection
This paper proposes a method for detecting copy-move forgery over images tampered by copying some regions and pasting them onto other regions. To detect those forgeries, we divide the given image into overlapping blocks, extract feature for each blocks, and sort the extracted feature vectors by radix sort. The difference (shift vector) of the coordinates of every pair of adjacent vectors in the...
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...
