Parameters:

handle – [in] Handle to the operator.
- Must not be NULL.
stream – [in] Handle to a valid CUDA stream.
in – [in] input tensor.
histogram – [out] output histogram, with width of 256 and a height = N on input tensor (1 if HWC tensor).
mask – [in] mask tensor, with shape the same as input tensor any value != 0 will be counted in the histogram.

Return values:

NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.
NVCV_ERROR_INTERNAL – Internal error in the operator, invalid types passed in.
NVCV_SUCCESS – Operation executed successfully.
