Metamer mismatching is a phenomenon that two objects, which are colorimetrically indistinguishable under one lighting condition, become distinguishable under another one.
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...
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...
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.
In this article, a camera response formation model is proposed to accurately predict the responses of images captured under various exposure settings.
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).
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...
