I have to connect nearby contours in an image based on the distance between them which specifies if the contours are to be connected.
Now there's a question already on the same problem here https://stackoverflow.com/questions/8973017/opencv-c-obj-c-connect-nearby-contours but here he merges all contours into a single one. This I don't want. I don't think that there is some function in opencv for this but you can suggest an algorithm for that. My application goes like this:
I'm detecting hands, so I used a skin detection algorithm to determine them but since my skin ain't white and maybe because of lightening conditions sometime the contour breaks of at elbow. So i want the nearby contours to be connected but not all of them (because both both my hands will be there in contours.) (By hands I mean from shoulder to palm.)
Moreover I think that by using some edge detection I will get my hands boundaries and detect if some of this patch inside this boundary is detected as skin then whole region within this boundary will be detected as skin but i'm not sure how to do this part.
Any Help will be appreciated. Thanks in advance
In this Image I wanna connect points (8 connectivity) which are less than say 40 pixels of distance so that I'll get my left hand as a single contour
My aim is to only get hand's contour (I don't care about any other region)
