| Title: | Restoration of halftoned color-quantized images using projection onto convex sets | Authors: | Fung, YH Chan, YH |
Issue Date: | 2004 | Source: | ICIP 2004 : 2004 International Conference on Image Processing : Singapore, 24-27 October 2004, p. 325-328 | Abstract: | Restoration of color-quantized images is rarely addressed in the literature especially when the images are color-quantized with halftoning. Direct applications of existing restoration techniques are generally inadequate to deal with this problem. In this paper, we propose a POCS-based restoration algorithm to solve the problem. This algorithm derives useful information for restoration with the available color palette and the mechanism of a halftoning process. It is shown to be able to provide a good restoration result. | Keywords: | Algorithms Bandwidth Color image processing Computer simulation Database systems Low pass filters Multimedia systems Vector quantization |
