Metamer mismatching is a phenomenon that two objects, which are colorimetrically indistinguishable under one lighting condition, become distinguishable under another one.
Comparison of object-color and illuminant metamerism for digital image color correction
Since the number of channels of an RGB camera is less than that required to represent the spectral information, the variation of either the captured object or the illuminant may introduce color reproduction errors when transforming device-dependent RGB values to device...
Image quality evaluation of HDR displays
The demand of accurate and pleasant image reproduction for displays has been important in recent years. Being limited by their small dynamic range, however, the usual displays can hardly reproduce the actual luminance of real scenes effectively. In response to the requirement of...
Spectral reflectance database from hyperspectral images
To evaluate the image quality deterioration caused by metamerism for digital cameras' color correction, I collected 43,714,197 spectral reflectance data from several public databases and preprocessed them so that finally 7,326,497 reliable reflectance data were obtained.
Camera response prediction for various capture settings using the spectral sensitivity and crosstalk model
In this article, a camera response formation model is proposed to accurately predict the responses of images captured under various exposure settings.
Rockchip on-chip auto white balance, lens shading correction and color correction image signal processing (ISP) pipeline
In this project, we proposed an on-chip ISP solution for mobile devices, including camera spectral sensitivity estimation, auto white balance (AWB) algorithm, color lens shading correction (LSC) and color correction (CC).
Impacting factors on camera calibration for spectral sensitivity estimation
In order for the improvement of calibration efficiency, it was investigated in this study that how the changes of the training samples selection would influence the estimation results and how many color samples at least should be included to achieve a high-fidelity color...
