Title: | A technique for lossy compression of error-diffused halftones | Authors: | Cheung, SM Chan, YH |
Issue Date: | 2004 | Source: | ICME : 2004 IEEE International Conference Multimedia and Expo : Taipei, Taiwan, June 27-30, 2004, p. 1083-1086 (CD) | Abstract: | In this paper, a new technique for lossy compression of halftone images is proposed based on the vector quantization technique. A conventional vector quantization encoder is modified such that it embeds a block-based error diffusion process and takes a HVS model into account during the compression. This modification significantly improves the visual performance of encoded images while the compression ratio achieved is identical to that of vector quantization. | Keywords: | Image coding Matrix algebra Modulation Nyquist diagrams Signal filtering and prediction Transfer functions Vector quantization |
