ippStsZeroMaskValuesErr
Masked image operations use nonzero mask samples to choose which pixels participate. A mask filled entirely with zero values selects no pixels, so the requested operation has no active region.
This differs from a null mask pointer. The mask is present and readable, but its content disables every pixel in the ROI.
Check these details
- Whether the mask was thresholded with the wrong polarity.
- Mask ROI, mask step and alignment with the source image ROI.
- Whether an earlier operation cleared the mask before reuse.
