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

Abstract: 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.

“…Take the color difference of dyed veneer before and after washing as the index of washing colorfastness grade [33], and classify the colorfastness grade according to GB/T 250-2008 [34] Gray Sample Card for Evaluating Color Change, as shown in Table 2. Put 100 mL pure water into a 250 mL beaker, then add the dyed poplar veneer whose chromaticity value has been measured and heat it in a constant temperature water bath at 60 • C for 2 h. After that, take out the sample and wash away the floating color.…”
