ARGUMENTSsrc
FUNCTIONgapi_boundingRect2
RETURN TYPEGOpaque_Rect
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Calculates the up-right bounding rectangle of a point set or non-zero pixels of gray-scale image.

The function calculates and returns the minimal up-right bounding rectangle for the specified point set or non-zero pixels of gray-scale image.

Note: - Function textual ID is "org.opencv.imgproc.shape.boundingRectMat"

  • In case of a 2D points' set given, Mat should be 2-dimensional, have a single row or column if there are 2 channels, or have 2 columns if there is a single channel. Mat should have either CV_32S or CV_32F depth
gapi_boundingRect2(src: GArray_Point2f): GOpaque_Rect;
src

Input gray-scale image CV_8UC1; or input set of CV_32S or CV_32F 2D points stored in Mat.

Returns

The GOpaque_Rect result. Release returned native handles with using or delete(), including handles nested in results.
