 | MatConvexityDefectsAsVec Method |
Computes the contour convexity defects
Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
SyntaxParameters
- convexHull
- Type: OpenCvSharpInputArray
Convex hull obtained using convexHull() that should contain indices of the contour points that make the hull.
Return Value
Type: Vec4iThe output vector of convexity defects. Each convexity defect is represented as 4-element integer vector (a.k.a. cv::Vec4i): (start_index, end_index, farthest_pt_index, fixpt_depth), where indices are 0-based indices in the original contour of the convexity defect beginning, end and the farthest point, and fixpt_depth is fixed-point approximation (with 8 fractional bits) of the distance between the farthest contour point and the hull. That is, to get the floating-point value of the depth will be fixpt_depth/256.0.
