詳解

A simple Hausdorff distance measure between shapes defined by contours

according to the paper "Comparing Images using the Hausdorff distance." by D.P. Huttenlocher, G.A. Klanderman, and W.J. Rucklidge. (PAMI 1993). :

関数詳解

setDistanceFlag()

virtual CV_WRAP void cv::HausdorffDistanceExtractor::setDistanceFlag ( int  distanceFlag )

pure virtual

Set the norm used to compute the Hausdorff value between two shapes. It can be L1 or L2 norm.

引数

distanceFlag

Flag indicating which norm is used to compute the Hausdorff distance (NORM_L1, NORM_L2).

setRankProportion()

virtual CV_WRAP void cv::HausdorffDistanceExtractor::setRankProportion ( float  rankProportion )

pure virtual

This method sets the rank proportion (or fractional value) that establish the Kth ranked value of the partial Hausdorff distance. Experimentally had been shown that 0.6 is a good value to compare shapes.

引数

rankProportion

fractional value (between 0 and 1).
