Lossless or near-lossless compression for high resolution image is required to meet the increasingly high quality demands in various application fields. With respect to this requirement, ultra-high definition image/video compression technology is researched in this papar. We first delve into the JPEG XR compression algorithm and parameters, then report a comparative study evaluating rate-distortion performance between JPEG XR, H.264 and JPEG 2000. A set of five sequences with resolution of 4K(3840x2160) have been used. The Result shows that, for the test sequences used to carry out the experiments, the JPEG XR outperforms other two coding standards in terms of the trade off between compression efficiency and hardware complexity.
