Reversible Integer Color Transform
Soo‐Chang Pei, Jian–Jiun Ding · IEEE Transactions on Image Processing · 2007
In this correspondence, we introduce a systematic algorithm that can convert any 3 x 3 color transform into a reversible integer-to-integer transform. We also discuss the ways to improve accuracy and reduce implementation complexity. We derive the integer RGB-to-KLA, IV1 V2, YCbCr, DCT, YUV, and YIQ transforms that are optimal in accuracy.
