| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A new standard referred to as JPEG XT has been designing to provide coded data for HDR images. JPEG XT coded data contains two layers: the base-layer for tone-mapped LDR version of an HDR image and the enhancement layer. The legacy JPEG decoder can understand the base-layer of JPEG XT coded data because it has the same codestream syntax as the legacy JPEG. In this study,it is firstly pointed out that there is a mismatch on the handling of the quantization error between the normative encoder and the standard decoder. Next,to avoid the problem, a improved encoder structure with consideration of the mismatch is proposed. The experimental results demonstrate that the proposed structure can give better coding performances than those of the normative encoder, while keeping compatibility with the JPEG XT decoder. | |
