I'm having troubles using OpenCV in processing 2.0b7 and 2.0b8 on WIN7 64. i've installed the binaries and put the openCV bin in my system PATH variable. i've installed the OpenCV libraries in my processing sketchbook/libraries folder. but when i open the blobs example from the OpenCV examples i get the following error: >Cannot find class or type named "Rectangle"<

here is the code from the example: ANY help would be much appreciated!!

import hypermedia.video.*;


OpenCV opencv;

int w = 320;
int h = 240;
int threshold = 80;

boolean find=true;

PFont font;

void setup() {

    size( w*2+30, h*2+30 );

    opencv = new OpenCV( this );
    opencv.capture(w,h);

    font = loadFont( "AndaleMono.vlw" );

First of all, rSi, it is kind of arrogant to hijack someone his thread to actually post a second problem. So please remove the notice and create your own.

I am not familiar with the processing software, but please, follow the next guide. It goes step by step through getting OpenCV to work with processing.

However it seems this is not done with the original openCV code, but by a port made by a guy named Peter Kirn. Basically this means that this is not the correct place to address your problems.

thanks for your answer! i'm a bit confused, because following the link you posted i could not find a tutorial on installing openCV... how to use it with processing is well documented. i was confused, because processing.org points you to: http://ubaa.net/shared/processing/opencv/ for the windows binaries you need to use with processing. i didn't know that its a different code base. thanks!

Add this on top of your code:

import java.awt.Rectangle;
