Function Documentation

double compare_contours	(	std::vector< std::vector< cv::Point > > &	contourA,
		std::vector< std::vector< cv::Point > > &	contourB
	)

Compares two contours and returns their overlap.

The return value uses the larger of the two contour sets as the base This means that, for example, if the first set of contours encloses the second but is twice as large, the resulting value will be 0.5, which is the same value as if the first was only half the size as the second

Parameters

contourA	first contour to compare
contourB	second contour to compare

Returns

Overlap between the two Contours, 1 being a complete match, 0 being a complete mismatch
