Recently, a novel approach to color image compression based on colorization has been presented. Although the conventional method of colorization-based coding outperforms JPEG in terms of subjective quality, the decoded chrominance components lose the local oscillation that the original images had. A large number of color assignations is required to restore these oscillations. We focus on the local...
Detection of demosaicing characteristics based on correlation at pixel level is useful for image forensic purposes. In this paper, we propose a new model to detect the demosaicing characteristics based on the second-order derivative correlation. Without the influences of the uneven DC components in the three color channels, the new model can estimate both intra-channel and cross-channel correlation...
