Hi everoyne,

I wanted to use the shape module to compute Hausdorff distance and shape context distance between two shapes, but it give me the error "Assertion failed (set1.channels()==2 && set.1cols>0)"
my Code :
InputArray src = imread("samples/5.jpg");
InputArray model = imread("samples/6.jpg");
Ptr<hausdorffdistanceextractor> p = createHausdorffDistanceExtractor();
float dis = p->computeDistance(src, model);

So, why the input must be 2 channels ?

Thanks, Mimic
