Abstract

This paper presents the importance of photo core transform in JPEG-XR/HD. Integer based coding technology is the basis for JPEG-XR/HD image compression system. Different HDR formats can be compressed by using this JPEG-XR/HD system. The main advantage of pulse core transform (PCT) is high compression efficiency and less computational complexity. In JPEG-XR/HD image compression system the photo core transform has been used to perform compression. Photo core transform based JPEG-XR/HD image compression system has been widely used in real time embedded applications. Adder, shifter and parallel multiplier circuits are used for the implementation of this photo core transform. By using this design it is possible to reduce the area, cost and power consumption.
