ippStsLnNegArg

Real-valued logarithm is outside its domain for negative inputs. IPP reports this warning when a logarithm primitive sees negative elements and handles them according to its special-case rules.

This typically indicates a preprocessing error in magnitude, power or probability data. Check the producer of the values before changing the logarithm call itself.

Check these details

Negative elements after filtering, subtraction or normalization.
Whether the algorithm should use absolute values, magnitude squared or complex-domain handling.
Special-case output expected by the chosen data type variant.
