/// <returns>The 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. </returns>
