Normalization mode Normalization mode. The normalization modes are:

0: no normalization
1: per channel normalization
2: channel-linked normalization
Channel-linked normalization may be of limited value for video signals where the alpha channel is composed of all zero values. Normalization Normalization flag (default = 0) When the flag is set, histogram values to the range [0, normval] are normalized.
