Image-dependent Color Mapping for Pleasant Image Renditions

摘要

This paper presents an image-dependent color mapping strategy to get the pleasant color renditions from two different approaches: (1) Mapping by Image Segmentation (MAPSEG) (2) Mapping by Histogram Specification (MAPHIST). MAPSEG is basically applied to match the device color to known original. The mappings are performed for the principal component (PC) to be matched in between the segmented areas of original and printed images. MAPHIST works to recover the faded or degraded colors for unknown original. It expands the de-saturated image gamut by Gaussian histogram specification (GHS) and makes full use of device gamut to render the pleasant images.
