Over the past years, digital images have been widely used in the Internet and other
applications. Whilst image processing techniques are developing at a rapid speed …

Digital images can be forged easily with today's widely available image processing software.
In this paper, we describe a passive approach to detect digital forgeries by checking …

Rapid technology development and the widespread use of visual sensors have led to a
number of new problems related to protecting intellectual property rights, handling patent …

Computer graphics generated by advanced rendering software come to appear so
photorealistic that it has become difficult for people to visually differentiate them from …

Why does placing an object from one photograph into another often make the colors of that
object suddenly look wrong? One possibility is that humans prefer distributions of colors that …

In this paper, we present a scheme based on feature mining and neuro-fuzzy inference
system for detecting LSB matching steganography in grayscale images, which is a very …

In this paper, we introduce a new image descriptor for broad Image Categorization, the
Progressive Randomization (PR) that uses perturbations on the values of the Least …

We presented a set of physics motivated features for classifying photographic and computer
graphic images in our previous work [1]. We also deployed an online demo system for …

Passive-blind image forensics (PBIF) refers to passive ways for evaluating image
authenticity and detecting fake images. This dissertation proposes a physics-based …

由于有功能强大的计算机和图像处理软件的存在, 普通用户可以将数字图像篡改成他们想得到的
