MatFindContoursAsArray Method OpenCvSharp Class Library
Finds contours in a binary image. The source is an 8-bit single-channel image. Non-zero pixels are treated as 1’s. Zero pixels remain 0’s, so the image is treated as binary. The function modifies this image while extracting the contours.

Syntax

public Point[][] FindContoursAsArray(
	ContourRetrieval mode,
	ContourChain method,
	Nullable<Point> offset = null
)

Parameters

mode
Type: OpenCvSharpContourRetrieval
Contour retrieval mode
method
Type: OpenCvSharpContourChain
Contour approximation method
offset (Optional)
Type: SystemNullablePoint
Optional offset by which every contour point is shifted. This is useful if the contours are extracted from the image ROI and then they should be analyzed in the whole image context.

Return Value

Type: Point
Detected contours. Each contour is stored as a vector of points.
