Circle in LCD that follows webcam colour tracking

    Nov 19 2013 | 9:16 am
    Hi all, sorry for the basic question.
    How do I get draw 1 circle in a LCD that moves in x and y position according to the x and y of a colour tracking object in a webcam?
    I've already have done the webcam colour tracking part and have problems drawing the circle. I used paintoval to draw the shape but I can't get it to move.
    Thank you.

      This should do it. Just erase all the drunk stuff and link your incoming colour tracking x, y cords to the number boxes. You need the [clear] object to erase the previous position of the circle in the LCD or you will end up drawing a line.
      If you don't mind, please let me see how you dealt with the colour tracking part of the patch as i'm interested in making a similar patch using blob recognition of some sort.

      Here is the same patch hooked up to "Tutorial 25: Tracking the Position of a Color in a Movie". The example is very simple and colour tracking on live video gets more complicated so i'm keen to see how you are dealing with it.

      Thanks for your patches, in the end I used nodes for my project tight deadline. Looking back, lcd is the more suitable choice. Thanks. Here's my colour tracking patch. I used bits and pieces from various tutorial. Hope it helps.
