- cvcuda.warp_affine(src: nvcv.Tensor, xform: nvcv.Tensor, flags: nvcv.Tensor, border_mode: cvcuda.Border = cvcuda.Border.CONSTANT, border_value: numpy.ndarray, stream: Optional[nvcv.cuda.Stream] = None) nvcv.Tensor
Executes the Warp Affine operation on the given cuda stream.

Refer to the CV-CUDA C API reference for the Warp Affine operator for more details and usage examples.
- Parameters:
src (nvcv.Tensor) – Input tensor containing one or more images.
xform (nvcv.Tensor) – 2x3 float affine transformation matrix.
flags (int) – Combination of interpolation methods(cvcuda.Interp.NEAREST, cvcuda.Interp.LINEAR or cvcuda.Interp.CUBIC) and the optional flag cvcuda.Interp.WARP_INVERSE_MAP, that sets xform as the inverse transformation.
border_mode (cvcuda.Border, optional) – Pixel extrapolation method (cvcuda.Border.CONSTANT or cvcuda.Border.REPLICATE).
border_value (numpy.ndarray, optional) – Used to specify values for a constant border, must be a size <= 4 and dim of 1, where the values specify the border color for each color channel.
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.
