Unable to get full resoultion

I'm unable to get the full resolution for following code

    //find frequency with highest amplitude

Format the code properly, it's difficult to read. Leave one blanks row before you, and press CTRL+K or the C button in the editing menu.

To go full screen with the frame use size(displayWidth, displayHeight);. To go full screen without the frame comment size() and add this to the bottom:

 boolean sketchFullScreen() {
      return true;
 }

The reason you cannot go full screen is that your camera doesn't support it unless you have an HD camera. The cols and rows take the value of the screen and not the value of the camera and therefore you will get an error. Also that example is outdated. There is a nice pixelation camera here openprocessing.org/sketch/131816
