Refer to the CV-CUDA C API reference for the Threshold operator for more details and usage examples.

Parameters

  • src (nvcv.Tensor) – Input tensor containing one or more images.

  • thresh (nvcv.Tensor) – An array of size batch that gives the threshold value of each image.

  • maxval (nvcv.Tensor) – An array of size batch that gives the maxval value of each image, using with the cvcuda.ThresholdType.BINARY or cvcuda.ThresholdType.BINARY_INV threshold types.

  • type (cvcuda.ThresholdType) – Thresholding type.

  • stream (nvcv.cuda.Stream, optional) – CUDA Stream on which to perform the operation.

Returns

The output tensor.

Return type

nvcv.Tensor

Caution

Restrictions to several arguments may apply. Check the C API references of the CV-CUDA operator.
