ippStsCoeffErr ippStsDitherLevelsErr

ippStsNoiseValErr

Dithering routines add controlled noise before quantization or conversion. A negative or otherwise invalid noise amplitude breaks the statistical assumptions of that operation.

This status points to the dither configuration, not to random-number generation itself.

Check these details for ippStsNoiseValErr

  • Amplitude value after scaling to the destination format.
  • Whether the caller confuses variance with amplitude.
  • That the selected dither type supports the requested noise settings.
