ColorTwist

cvcuda.color_twist(*args, **kwargs)

Overloaded function.

1. color_twist(src: nvcv.Tensor, twist: nvcv.Tensor, *, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.Tensor

   cvcuda.color_twist(src: nvcv.Tensor, twist: nvcv.Tensor, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.Tensor

   Transforms an image by applying affine transformation to the channels extent.

   See Also:

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

   Args:

   src (nvcv.Tensor): Tensor corresponding to the input image. It must have

   either 3 or 4 channels. In the case of 4 channels, the alpha channel is unmodified.

   twist (nvcv.Tensor): A 2D tensor describing a 3x4 affine transformation matrix. stream (nvcv.cuda.Stream, optional): CUDA Stream on which to perform the operation.

   Returns:

   nvcv.Tensor: The output tensor.

2. color_twist(src: nvcv.ImageBatchVarShape, twist: nvcv.Tensor, *, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.ImageBatchVarShape

   cvcuda.color_twist(src: nvcv.ImageBatchVarShape, twist: nvcv.Tensor, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.ImageBatchVarShape

   Transforms a batch of images by applying affine transformation to the channels extent.

   See Also:

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

   Args:

   src (nvcv.ImageBatchVarShape): Input image batch. Each image must have either 3 or 4

   channels. In the case of 4 channels the alpha channel is unmodified.

   twist (nvcv.Tensor): A 3x4 2D tensor describing an affine transformation matrix or a

   Nx3x4 3D tensor specifying separate transformations for each sample in the input image batch.

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

   Returns:

   nvcv.ImageBatchVarShape: The output image batch.

cvcuda.color_twist_into(*args, **kwargs)

Overloaded function.

1. color_twist_into(dst: nvcv.Tensor, src: nvcv.Tensor, twist: nvcv.Tensor, *, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.Tensor

   cvcuda.color_twist_into(dst: nvcv.Tensor, src: nvcv.Tensor, twist: nvcv.Tensor, stream: Optional[nvcv.cuda.Stream] = None)

   Transforms an image by applying affine transformation to the channels extent.

   See Also:

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

   Args:

   dst (nvcv.Tensor): Tensor corresponding to the output image. Must match the shape of

   the input image.

   src (nvcv.Tensor): Tensor corresponding to the input image. It must have

   either 3 or 4 channels. In the case of 4 channels, the alpha channel is unmodified.

   twist (nvcv.Tensor): A 2D tensor describing a 3x4 affine transformation matrix. stream (nvcv.cuda.Stream, optional): CUDA Stream on which to perform the operation.

   Returns:

   None

2. color_twist_into(dst: nvcv.ImageBatchVarShape, src: nvcv.ImageBatchVarShape, twist: nvcv.Tensor, *, stream: Optional[nvcv.cuda.Stream] = None) -> nvcv.ImageBatchVarShape

   cvcuda.color_twist_into(dst: nvcv.ImageBatchVarShape, src: nvcv.ImageBatchVarShape, twist: nvcv.Tensor, stream: Optional[nvcv.cuda.Stream] = None)

   Transforms a batch of images by applying affine transformation to the channels extent.

   The twist should be a 2D tensor describing 3x4 affine transformation matrix or a 3D tensor specifying separate transformations for each sample in the input image batch.

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

   Args:

   dst (nvcv.ImageBatchVarShape): Output image batch. The shapes of the output images

   must match the input image batch.

   src (nvcv.ImageBatchVarShape): Input image batch. Each image must have either 3 or 4

   channels. In the case of 4 channels the alpha channel is unmodified.

   twist (nvcv.Tensor): A 3x4 2D tensor describing an affine transformation matrix or an

   Nx3x4 3D tensor specifying separate transformations for each sample in the input image batch.

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