Abstract
Anyone with average knowledge about image editing software can modify an image and make people believe it is the real image. One type of image modification is to copy a portion of an image, change its brightness, and paste it onto another location. In this paper, we are intending a method to perceive the brightness changes in the copy-pasted region of a colour image by applying LBP (Local Binary Pattern) on all three channels R(red), G(green), and B(blue) of an image. After the application of the LBP, the image is separated into overlapping blocks, and those blocks with equal LBP values in each channel indicate brightness or contrast modified pasted regions. Each of the channels detected regions are combined to identify brightness change in the duplicated region of the image.
