MinAreaRect

cvcuda.minarearect(src: nvcv.Tensor, numPointsInContour: nvcv.Tensor, totalContours: int, *, stream: Optional[nvcv.cuda.Stream] = None) → nvcv.Tensor

Executes the Min Area Rect operation on the given cuda stream.

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

Parameters

  • src (nvcv.Tensor) – Input tensor containing one or more contours.src[i,j,k] is the set of contours where i ranges from 0 to batch-1, j ranges from 0 to max number of points in cotours k is the coordinate of each points which is in [0,1]

  • numPointsInContour (nvcv.Tensor) – Input tensor containing the number of points in each input contours.

  • totalContours (int) – Number of input contours

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

Returns

The output tensor of rotated bounding boxes.The output will give 4 points’ cooridinate(x,y) of each contour’s minimum rotated bounding boxes

Return type

nvcv.Tensor

Caution

Restrictions to several arguments may apply. Check the C API references of the CV-CUDA operator.
