Improving the Global Impression of Brightness of the Multi Scale Retinex Algorithm for Wide Dynamic Range Pictures

چکیده
This paper addresses the problem of wide dynamic range scenes and presents a new method of compressing the dynamic range of wide dynamic range scenes. This method is based on the Multiscale Retinex Algorithm. The paper presents the performance of the Multiscale Retinex Algorithm on wide dynamic range pictures. Two modifications that enhance the results obtained with the original Multi Scale Retinex algorithm for wide dynamic range pictures are proposed. The first modification is obtained by the recombination of the resulting image with the original picture in a certain weight. The second modification is achieved by adjusting the histogram of the resulting picture. The modifications improve the results of the original Multi Scale Retinex Algorithm in a way that retains the global contrast of brightness and the natural impression of the resulting image. The paper explores the performance of this modified algorithm on different wide dynamic range scenes and points out its advantages over other dynamic range compression algorithms.

Tone Mapping Algorithm for Luminance Separated HDR Rendering Based on Visual Brightness Functions
Tone mapping algorithms are used in image processing that reduces the range of high dynamic range (HDR) image to be displayed on low dynamic range (LDR) devices. The retinex method is one of the tone mapping algorithms to provide dynamic range compression, color constancy, and color rendition. It has been developed from single scale methods to multi-scale methods. Retinex algorithms still have ...

متن کاملRetinex Image Processing: Improving the Visual Realism of Color Images
Sensations of color show a strong correlation with reflectance, even though the amount of visible light reaching the eye depends on the product of reflectance and illumination. The visual system must achieve this remarkable result by a scheme that does not measure flux. Such a scheme is described as the basis of Retinex theory. This paper deals with image enhancement techniques basically Retine...
متن کاملMulti-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 کاملAdaptive Multi-Scale Retinex algorithm for contrast enhancement of real world scenes
Contrast enhancement is a classic image restoration technique that traditionally has been performed using forms of histogram equalization. While effective these techniques often introduce unrealistic tonal rendition in real-world scenes. This paper explores the use of Retinex theory to perform contrast enhancement of real-world scenes. We propose an improvement to the Multi-Scale Retinex algori...
