huffman algorithm and adaptive huffman algorithm binary image using matlab

Consider a black and white image. This image is made up of many pixels that are all different shades of gray which have a number value corresponding to the brightness or darkness of the shade. Black is 0, white is 255, and all the numbers in between are shades of gray. So, each pixel is coded as some integer from 0 to 255. In order to encode these integers, we must use bits. A bit have a value of either 0 or 1, and the maximum number of bits needed to code any number be ....etc

image copy move forgery detection ppt

What is the best algorithm for copy-move forgery detection (CMFD)?
A copy-move forgery is created by copying and pasting content within the same image, and potentially postprocessing it. In recent years, the detection of copy-move forgeries has become one of the most actively researched topics in blind image forensics. A considerable number of different algorithms have been proposed focusing on different types of postprocessed copies.In our paper An Evaluation of Popular Copy-Move Forgery Detection Approa ....etc

Abstract

Each image has its own unique characteristics or properties. When we edit an image we are changing these characteristics and by examining the changes in the characteristics we can determine whether the image is edited or not. Image editing can be of two types, usual editing and copy move forgery. In copy-move forgery a part of original digital image is copied and pasted to another part in the same original image to make it, forged one. Because the copied part comes from the same image, its important properties will be compatible with ....etc
