Multi-scale retinex for color image enhancement
The retinex is a human perception-based image processing algorithm which provides color constancy and dynamic range compression. We have previously reported on a single-scale retinex (SSR) and shown that it can either achieve color/lightness rendition or dynamic range compression, but not both simultaneously. We now present a multi-scale retinex (MSR) which overcomes this limitation for most sc...
متن کاملColor Image Enhancement Using Multiscale Retinex and Image Fusion Techniques
Abstract—In this paper, an edge-strength guided multiscale retinex (EGMSR) approach will be proposed for color image contrast enhancement. In EGMSR, the pixel-dependent weight associated with each pixel in the single scale retinex output image is computed according to the edge strength around this pixel in order to prevent from over-enhancing the noises contained in the smooth dark/bright regio...
متن کاملColor image enhancement using a Retinex-based digital filter
We present a new adaptation of Retinex to enhance the rendering of high dynamic range digital color images. The image is processed using an adaptive Gaussian filter. The shape of the filter basis is adapted to follow the high contrasted edges of the image. In this way, the artifacts introduced by a circularly symmetric filter at the border of high contrasted areas are reduced. This method provi...
متن کاملRetinex at 50: color theory and spatial algorithms, a review
Retinex Imaging shares two distinct elements: first, a model of human color vision; second, a spatialimaging algorithm for making better reproductions. Edwin Land’s 1964 Retinex Color Theory began as a model of human color vision of real complex scenes. He designed many experiments, such as Color Mondrians, to understand why retinal cone quanta catch fails to predict color constancy. Land’s Ret...
متن کاملRetinex processing for automatic image enhancement
There has been a revivification of interest in the Retinex computation in the last six or seven years, especially in its use for image enhancement. In his last published concept (1986) for a Retinex computation, Land introduced a center/surround spatial form, which was inspired by the receptive field structures of neurophysiology. With this as our starting point, we develop the Retinex concept ...
