| Title: | Restoring halftoned color-quantized images with simulated annealing | Authors: | Fung, YH Chan, YH |
Issue Date: | 2004 | Source: | ICME : 2004 IEEE International Conference Multimedia and Expo : Taipei, Taiwan, June 27-30, 2004, p. 367-370 (CD) | 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, a restoration algorithm based on simulated annealing is proposed to solve the problem. This algorithm makes a good use of the available color palette and the mechanism of a halftoning process to derive useful a priori information for restoration. It is shown to be able to provide a good restoration result. | Keywords: | Algorithms Computer simulation Error analysis Image coding Image reconstruction Information theory Problem solving Set theory Signal filtering and prediction Simulated annealing Vector quantization |
