Lossless two-layer coding for HDR images
Description
A lossless two-layer coding scheme for HDR images using a histogram packing technique is proposed for HDR images in this paper. The proposed scheme has the compatibility with the legacy JPEG for base layer as well as the normative JPEG XT standard. A histogram packing technique is applied to residual images to improve the performance of lossless compression. The experimental result for the bitrates of the encoded bitstreams demonstrates that the proposed structure gives a better coding performance than the normative JPEG XT profile C.
