How can I use the NormHistogramCostExtractor class? What function do I need to call to extract the cost? What are the arguments to be passed ?
What does norm based cost extraction mean? Do I have to normalize the histogram and then pass the normalized histograms for cost extraction as in EMDL1 or anything else? Please provide suggestions.
are you trying to compare shapes ? i never tried the shape module, but looking at the tests it seems, you'd just pass an instance to the ShapeContextDistanceExtractor, and let the latter compute the distance.
