| Abstract;This paper proposes a simple and easy method for 3D gamut comparison between image and device. A quick decision whether each pixel is located at inside of the device gamut or not, is necessary to execute 3D I-D GM. In this paper, both 3D image and device gamut shells are shaped as polygon meshes in the segmented discrete polar angle (.PHI., .THETA.) by extracting the most outside points from the random color distributions of source image. The image and device gamut boundaries are quickly compared between polar angle segments and the pixels located at the outside of device gamut are automatically separated. A variety of image gamut shapes are compared with that of inkjet printer and experimental results in 3D Image-to-Device GMA are reported. (author abst.) |
