3.1.3.4 Y’FbFr
Y’FbFr [15] is another color space built upon on the same ideas as Y’CoCg:
making use of the KLT to design an integer reversible color transform with
a high coding gain and low bit expansion.
Not only does it share its design ideas with Y’CoCg, but also the way it has been
implemented through a lifting scheme [13] in which each pixel is computable with
five additions and three bit shifts.
