Quantifying Color Image Distortions Based On Adaptive Spatio-chromatic Signal Decompositions
We describe a framework for quantifying color image distortion based on an adaptive signal decomposition. Specifically, local blocks of the image error are decomposed using a set ...

A Perceptual Distortion Metric for Digital Color Images
This paper presents a comprehensive distortion metric for digital color images. It is based on a normalization model of the human visual system that incorporates color perception....

Nonlinear Distortion Correction in Endoscopic Video Images
Modern video-based endoscopes offer physicians a wide-angle field of view for minimally-invasive procedures. Unfortunately, inherent barrel distortion prevents accurate perception...

Perceptible Level Lines and Isoperimetric Ratio
This paper introduces a simple criterion to select the most important level lines from the numerous set obtained with a topographic map. A topographic map gives a morphological an...

Image forensic analyses that elude the human visual system
While historically we may have been overly trusting of photographs, in recent years there has been a backlash of sorts and the authenticity of photographs is now routinely questio...
