Hi I’m using processing to make some good project. explanation of project: Detect hand based on depth and draw the circle on each hand. Progress: I can find center but there’s issue. If two bunch of pixels exist, it’s not what i want it. I want to draw circle on the each hand. [22] souce cod…

hi Ieereset, What you are asking is really not clear and it is not because of your english. We miss 3 things: An example of your source data (the thing that you want to analyze) A clear explanation of what you want to acheive based on that example The code of what you have so far Rigth now on t…

Okay, it’s a bit more clear now. Still not the best but good enough :slight_smile: I guess that the red parts are where your hand are? And I guess that the problem that you have is that for the right hand, you have 3 sets of pixels instead of only one right? If this is the case, there are several…
