NVCVStatus cvcudaLaplacianVarShapeSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVImageBatchHandle in, NVCVImageBatchHandle out, NVCVTensorHandle ksize, NVCVTensorHandle scale, NVCVBorderType borderMode)

Executes the Laplacian operation on a batch of images.

Parameters:

  • in – [in] Input image batch.

  • out – [out] Output image batch.

  • ksize – [in] Aperture size to compute second-derivative filters, either 1 or 3 per image, as a 1D Tensor of int.

    • Must be of pixel type NVCV_DATA_TYPE_S32

  • scale – [in] Scale factor Laplacian values as a 1D Tensor of float.

    • Must be of pixel type NVCV_DATA_TYPE_F32

  • borderMode – [in] Border mode to be used when accessing elements outside input image, cf. NVCVBorderType.
