Color Tracking

This examples shows how to track a color from the live video feed.
The default color is a blue tone, you can change that by clicking on any pixel in the video feed and the application will now track that color.

There are 4 parameters for the ColorTracker object's constructor; width, height, color to track and a treshold. treshold is obselete and optional.

This movie requires Flash Player 9

 
package examples
{
	import flash.display.Sprite;
	import playground.src.video.ColorTracker;
	import playground.src.video.LiveCamera;
 
	public class ColorTracking extends Sprite
	{
 
		private var _cam:ColorTracker;
 
		public function ColorTracking()
		{
			_cam = new ColorTracker(320, 240, 0x44ddff, 10);
			addChild(_cam);
                        //this is how you can get the x and y coordinates of the pixel you are
                        //tracking as a Point object
                        trace(_cam.publicpos);
 
		}
 
	}
 
}

Hi, nice example of color tracking.
What colorspace to you use to match the colors (RGB, HSV, CIELab, … ). Are you using getColorBoundsRect() to extract the final region?

Greetings

Hello my name is Luis Rodriguez, I have been researching the detection of movement and now I’m researching the detection of color and movement, I would like you to see my work:

I wonder if you want to share your library as3 in this example with me so I can further my research, I would greatly appreciate

Hi Luis, I like what you got so far. How do you handle the movement detection? Difference in pixel matrix?

You can get all the files from here
http://servetulas.com/blog/playground_library/download/

It should be among one of the examples in there.

George, sorry for not replying earlier, just seeing your comment. I am using RGB and running through the image’s pixels to seek the color every frame.
