Reversible Integer Color Transform

In this correspondence, we introduce a systematic algorithm that can convert any 3 times 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, IV
