Composite

cvcuda.composite(foreground: nvcv.Tensor, background: nvcv.Tensor, fgmask: nvcv.Tensor, outchannels: int, stream: nvcv.cuda.Stream | None = None) → nvcv.Tensor

Executes the Composite operation on the given cuda stream.

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

Parameters:

  • foreground (nvcv.Tensor) – Input tensor containing one or more foreground images. Each image is BGR (3-channel) 8-bit.

  • background (nvcv.Tensor) – Input tensor containing one or more background images. Each image is BGR (3-channel) 8-bit.

  • fgmask (nvcv.Tensor) – Input foreground mask tensor. Each mask image is grayscale 8-bit

  • outchannels (int) – Specifies 3 channel for RGB and 4 channel for BGRA.

  • 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.
