Refer to the CV-CUDA C API reference for the Laplacian operator for more details and usage examples.
- Parameters:
src (nvcv.Tensor) – Input tensor containing one or more images.
ksize (int) – Aperture size used to compute the second-derivative filters, it can be 1 or 3.
scale (float) – Scale factor for the Laplacian values (use 1 for no scale).
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.
