Employment of YCrCb color space and OLED display for enhancement of hyperspectral images colors rendering

Colors transformations in the process of displays colors rendering require the compatibility between what the human eyes can see and what the display can render. A spectral image processing algorithm, D65 illumination standard, spectral part of the human eye and spectral part of the OLED display, are employed in display color correction and rendering. Display colors rendering consist of transforming hyperspectral images into RGB images using ITU.709 standard These images are then enhanced to obtain high dynamic range images. Next, the images are: processed, color enhanced and rendered using YCrCb color space. The proposed algorithm depicts details that are not well revealed in the ITU.709 color space image. Demonstrative images which illustrate the comparison between the reconstructed spectral images into ITU.709 color space and the enhanced final images rendered in YCrCb color space are presented.
