The angle between the RGBs of the measured illuminant and estimated illuminant colors—the recovery angular error—has been used to evaluate the performance of the illuminant estimation algorithms. However we noticed that this metric is not in line with how the illuminant estimates are used. Normally, the illuminant estimates are ‘divided out’ from the image to, hopefully, provide image colors that...
Illumination estimation is a well-studied topic in computer vision. Early work reported performance on benchmark datasets using simple statistical aggregates such as mean or median error. Recently, it has become accepted to report a wider range of statistics, e.g. top 25%, mean, and bottom 25% performance. While these additional statistics are more informative, their relationship across different...
The HEVC extension for Scalable Video Coding (SHVC) is currently under definition. Color Gamut Scalability (CGS) has been identified as one MPEG requirement. This paper discuss what could be the stake of CGS in the context of video distribution. Two CGS models are presented: one simple scheme based on Gain-Offset transformation, and one based on 3D color LUT, more generic. A comparison of their performances...
