I need to program my bot so that it is able to find an object that is it asked to pickup and bring it to the commanded position. I have tried simple img processing techniques like filtering, contour finding. that doesn't seems to work well. I want to use ORB feature extractor. here are a sample images. object of interest is the ball. In short how do I train my bot to pickup balls or other objects any sample program will be helpful. how to use ORB. provide an example if possible. is there a way to use it in C-api thanx in advance
