Contrast Enhancement Estimation for Digital Image Forensics
Inconsistency in contrast enhancement can be used to expose imagel forgeries. In this work, we describe a new method to estimate contrast enhancement from a single image. Our method takes advantage of the nature of contrast enhancement as a mapping between pixel values, and the distinct characteristics it introduces to the image pixel histogram. Our method recovers the original pixel histogram ...
متن کاملDeveloping a PC-based portal image contrast enhancement program
ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field. Methods: The software was written based on local enhancement of the pixel values in image ma...
متن کاملImage fusion-based contrast enhancement
The goal of contrast enhancement is to improve visibility of image details without introducing unrealistic visual appearances and/or unwanted artefacts. While global contrast-enhancement techniques enhance the overall contrast, their dependences on the global content of the image limit their ability to enhance local details. They also result in significant change in image brightness and introdu...

متن کاملRobust Contrast Enhancement Forensics Using Convolutional Neural Networks
Contrast enhancement(CE) forensics has always been attracted widely attention on image forensic community. It can provide an effective rule for recovering image history and identifying and locating tampered images. Although, a number of algorithms have been proposed, the robustness of CE forensics technique for common pre/post processings is not satisfactory. To deal with it, in this letter, we...
