| Title: | A new approach for restoring block-transform coded images with estimation of correlation matrices | Authors: | Choy, SSO Chan, YH Siu, WC |
Issue Date: | 1997 | Source: | International Conference on Image Processing : proceedings : October 26-29, 1997, Santa Barbara, California, v.2, p. 342-345 | Abstract: | This paper presents a new restoration approach to reduce coding artifacts in block-transform image coding. Different from conventional restoration techniques, the proposed one is non-iterative and requires light computational cost, yet can reconstruct objectively and subjectively better images. This good performance is achieved because of the following advantages the proposed approach has: (i) efficient incorporation of the solution bound into restoration; and (ii) effective exploitation of local image properties and statistical knowledge about the quantizers used. | Keywords: | Block codes Computational complexity Correlation methods Cost effectiveness Image coding Image compression Image quality Matrix algebra Parameter estimation Standards |
