I'm trying to learn the possibilities using OpenCV for Android. At this point i want to draw a rectangle on the image frames which is continuously supplied by the videocapture. Can any of you help you with this.

Thanks a lot

First of all use the Java docs to see what is implemented on

Look there at the core library, go to method summary and then look for your drawing function. This is what I found.

rectangle(Mat img, Point pt1, Point pt2, Scalar color)
// Draws a simple, thick, or filled up-right rectangle.

Hope this will solve your problem :)
