LOW-COST NIGHT VISION CAMERA BASED ON A MODIFIED CONSUMER WEBCAM AND LIGHTWEIGHT REAL-TIME ENHANCEMENT

Journal of Problems in Computer Science and Information Technologies
Low-light perception is a core requirement for robotics, inspection, and wearable situational awareness, yet reliable night- vision solutions often require expensive sensors or computation- ally heavy processing.

Multi-Scale Retinex For Color Image Enhancement

, 1996
The retinex is a human perception-based image processing algorithm which provides color constancy and dynamic range compression. We have previously reported on a singlescale retinex (SSR) and shown that it can either achieve color/lightness rendition or ...

DSP Implementation of the Retinex Image Enhancement Algorithm

, 2004
The Retinex is a general-purpose image enhancement algorithm that is used to produce good visual representations of scenes. It performs a non-linear spatial/spectral transform that synthesizes strong local contrast enhancement and color constancy. A real-

Algorithm for foggy image enhancement based on the total variational Retinex and gradient domain

Tongxin xuebao, 2014
Considering the preservation of color constancy and the improvement of contrast ratio of foggy image en-hancement, the foggy image enhancement algorithm based on the total variational Retinex gradient domain method was proposed.

A Comparison of the Multiscale Retinex With Other Image Enhancement Techniques

, 1997
The multiscale retinex with color restoration (MSRCR) has shown itself to be a very versatile automatic image enhancement algorithm that simultaneously provides dynamic range compression, color constancy, and color rendition. A number of algorithms exist

Mathematical definition and analysis of the Retinex algorithm

, 2005
We present a detailed mathematical analysis of the original Retinex algorithm due to Land and McCann [J. Opt. Soc. Am. 61, 1 (1071)]. To this end, we propose an analytic formula that describes the algorithm behavior.
