Title:
PERCEPTUAL COLOR ENHANCEMENT BASED ON PROPERTIES OF RESPONSES OF HUMAN VISION SYSTEM TO COLOR STIMULUS
Document Type and Number:
WIPO Patent Application WO/2022/103117
Kind Code:
A1
Abstract:
A method includes determining, by a computing device, a working color space of a source content and a resulting content. The computing device models color saturation variations of different hues in the working color space with one or more properties of responses of a human vision system (HVS) to color stimulus. The computing device generates one or more color saturation variation models based on the responses of the HVS to color stimulus. An input color is mapped from the source content to an output color in the working color space using the one or more color saturation variation models.
