Hi ,
From my current experience of working with images,i get a feel that crop pad dsnt some times goes well with circular object frame ,in a reflection mode it appends
incoherent circular arcs at the border (forming olympic symbol) and in padding mode zeros it appends black border after cutting circular boundaries ,all of which could be affecting the model learning . Currently this is done mandatorily as transformation. I think this should be an optional parameter or there should be a provision for circular cropping for circular object…
