Detailed description

When using SuperpixelSEEDS->getLabels(labels) to return labels mat data, I have receive an incorrect data. The actually NumberOfSuperpixels() is 48,but the numberofSuperpixels in labels is half of it(24). Half of the points in the labels mat are 0. Meanwhile,this return value is normal in python.
