Hi,

I have been using the OpenCV library to adapt some of my examples that used JMyron (OpenCV does background subtraction and thresholding) but I've run across a problem:

OpenCV maximum framerate seems to be 15 fps!

I've simplified my code to this:
Code:

import hypermedia.video.*;

OpenCV opencv;

void setup() {

 opencv = new OpenCV( this );
  opencv.capture(320,240);
}

void draw () {
  opencv.read();
   println(frameRate);
}
 

and compared it to this:
Code:

import JMyron.*;

JMyron m;

void setup() {

  m = new JMyron();
  m.start(320, 240);

}

void draw () {
   m.update();
   println(frameRate);
}
 

I tested three different webcams (2 brands) and the OpenCV version got only about 12-15 fps while the JMyron version got 25-35 fps.

Anyone knows why this is happening and if there's a way to make OpenCV faster?

I was really looking forward to using OpenCV since it has a lot of code I used to do manually because I thought it would be faster...

thanks
