Illuminant and gamma comprehensive normalisation in logRGB space
The light re ected from an object depends not only on object colours but also on lighting geometry and illuminant colour. As a consequence the raw colour recorded by a camera is not a reliable cue for object based tasks such as recognition and tracking. One solution to this problem is to nd functions of image colours that cancel out dependencies due to illumination. While many invariant functio...
متن کاملGamma Comprehensive Normalisation
The light reflected from an object depends not only on surface reflectance of the object but also on lighting geometry and illuminant color. As a consequence, the raw color recorded by a camera is not a reliable cue for color based tasks such as object recognition and tracking. One solution to this problem is to find color invariants which are independent of illumination. While many invariant f...

The light reflected from an object depends not only on object colours but also on lighting geometry and illuminant colour. As a consequence the raw colour recorded by a camera is not a reliable cue for object based tasks such as recognition and tracking. One solution to this problem is to find functions of image colours that cancel out dependencies due to illumination. While many invariant func...
متن کاملIlluminant Chromaticity Estimation using Dichromatic Slope and Dichromatic Line Space
In this paper, we present a novel dichromatic-based method for estimating illuminant chromaticity. The proposed method is essentially based on the Dichromatic Slope and Dichromatic Line Space that we introduce. Dichromatic slope is the slope of the dichromatic line that passes the image chromaticity of a pixel in chromaticity space. It is specularity-invariant and can be computed for each pixel...
متن کاملModeling of RF Waves in Free Space Optical Communication System Under Gamma-Gamma Turbulent Channel Effect
In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...
