Lossless Coding of HDR Color Images in a Floating Point Format Using Block-Adaptive Inter-Color Prediction

抄録

This paper proposes a lossless coding method for HDR color images stored in a floating point format called Radiance RGBE. In this method, three mantissa and a common exponent parts, each of which is represented in 8-bit depth, are encoded using the block-adaptive prediction technique with some modifications considering the data structure.
