| Abstract(in English) | In this paper, a novel JPEG coding scheme for high fidelity images is proposed. When high fidelity images are compressed with JPEG, the information which cannot be represented by JPEG-compliant 8-bit data must be truncated. This truncation causes the quality degradation, In order to suppress this quality degradation, in the proposed scheme, halftoning is used to represent pixels of a high fidelity image with JPEG-compliant 8-bit data. The effect of halftoning depends on the characteristics of image. So halftoning and rounding is applied for each of 8×8 size block to truncate the extra information, then the method which is applied for each block is decided by the quality criteria. Moreover, optimization of halftoning parameters using simulated annealing is demonstrated. |
