An Evaluation of Popular Copy-Move Forgery Detection Approaches
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 theExpand

Retinal vessel segmentation by improved matched filtering: evaluation on a new high-resolution fundus image database
Automatic assessment of retinal vessels plays an important role in the diagnosis of various eye, as well as systemic diseases. A public screening is highly desirable for prompt and effectiveExpand

Scene Illumination as an Indicator of Image Manipulation
The goal of blind image forensics is to distinguish original and manipulated images. We propose illumination color as a new indicator for the assessment of image authenticity. Many images exhibit aExpand

Multi-Illuminant Estimation With Conditional Random Fields
Most existing color constancy algorithms assume uniform illumination. However, in real-world scenes, this is not often the case. Thus, we propose a novel framework for estimating the colors ofExpand

Multispectral skin color modeling
The automated detection of humans in computer vision as well as the realistic rendering of people in computer graphics necessitates improved modeling of the human skin color. We describe theExpand

On rotation invariance in copy-move forgery detection
The goal of copy-move forgery detection is to find duplicated regions within the same image. Copy-move detection algorithms operate roughly as follows: extract blockwise feature vectors, find similarExpand

Writer Identification Using GMM Supervectors and Exemplar-SVMs
Abstract This paper describes a method for robust offline writer identification. We propose to use RootSIFT descriptors computed densely at the script contours. GMM supervectors are used as encodingExpand

ROCHADE: Robust Checkerboard Advanced Detection for Camera Calibration
We present a new checkerboard detection algorithm which is able to detect checkerboards at extreme poses, or checkerboards which are highly distorted due to lens distortion even on low-resolutionExpand

An endoscopic 3D scanner based on structured light
We present a new endoscopic 3D scanning system based on Single Shot Structured Light. The proposed design makes it possible to build an extremely small scanner. The sensor head contains aExpand

Color constancy and non-uniform illumination: Can existing algorithms work?
The color and distribution of illuminants can significantly alter the appearance of a scene. The goal of color constancy (CC) is to remove the color bias introduced by the illuminants. Most existingExpand
