Multiplier-less Lifting-based Photo Core Transform for JPEG XR Ultrasound Image Compression

The new standard of the JPEG community, called the JPEG XR, carries the features of its earlier standards, namely the JPEG Baseline and the JPEG 2000. JPEG Baseline and JPEG 2000 have been in extensive use since their introduction; and have pre-defined tools in various platforms, such as MATLAB, for simulation and testing purposes. However, the same doesn't apply to the latest JPEG XR standard and thus creates a barrier in the ease of use for the global community. JPEG XR employs photo core transform for still-image compression, and in this paper, we propose a novel software implantation of the forward and the inverse photo core transform, PCT and IPCT respectively. The implementations are lifting-based operations that can be made multiplier-less for hardware simplicity.
