I coded kmeans with 4,5 and more clusters but it didn't work because parts of leaflet have been tagged background and pa

the kmeans is done on what data : luminosity, saturation, hue ?... and look at the tooth upside there is a part of shado

OK can you post some snippets or better a complete code program so I can see ?

HFSSegment Hi, Has someone a documentation on HFSSegment please ? Thank you

if I tag the parts it is that I already know the parts but what I want to do is to discover them automatically

the method with saturation doesn't works : leaflets parts are tagged background (which was not the case with luminosity)

A person on channel #opencv advised me to use saturation for grayscale transformation before Otsu binarization instead o

Hi, I want to extract from a scan of a blackberry (Rubus sp) leaf the parts and theirs characteristic that is: - the length and the width of the leaflets - know which of the leaflets are the basals, terminals and laterals - calculate the width of the apex and the basal notch - the length of the petioles and petiolules Which knowlendge and OpenCV functions have I to use please ? Thank you.
