ippStsLnZeroArg
Natural logarithm is undefined at zero in real-valued arithmetic. IPP can report this warning when zero input elements are processed by logarithm routines.
The status explains output such as negative infinity or a substituted boundary value. It is not a pointer or stride problem.
Check these details
- Zero-valued samples in the logarithm input vector or image.
- Whether the caller should add an offset before log-domain processing.
- Downstream code that assumes all log results are finite.
