ippStsGrayCoefSumErr
RGB-to-gray and related color conversions use channel coefficients to combine components. IPP validates the coefficient set against the normalization rule of the selected function.
This status usually means the coefficient array was generated or scaled incorrectly. It is not a channel-order error: the channels may be correct while the weighting rule is not.
Check these details
- Coefficient sum after converting fixed-point or floating-point constants.
- Whether coefficients were intended for normalized 0..1 samples or integer ranges.
- Whether RGB and BGR order caused coefficients to be paired with the wrong channels.
