Threshold effect in image processing

 * Reason:It's a nice example of how thresholding can be used to good effect. One may want to think about making a composite or hover-over with the original as an alternative.

 * Comment it seems a little pointless on its own. Your idea about a composite would be better, I think; either splitting the image in half (before and after) or duplicating the whole image vertically (top before, bottom after). Matt Deres (talk) 17:19, 10 May 2008 (UTC)
 * Isn't there a way to do this as hover/rollover on Wikipedia? Papa Lima Whiskey (talk) 20:31, 10 May 2008 (UTC)
 * I don't think so; you'll note that our article on rollovers doesn't include any examples, only external links to examples. Matt Deres (talk) 23:34, 10 May 2008 (UTC)
 * Comment. I created and uploaded a composite if anybody prefers that. Nautica Shad es  03:38, 11 May 2008 (UTC)
 * Oppose both. The source image has very poor technical quality, and given the ease with which an example like this can be created a better quality image should be used.  Admittedly this isn't vital for the non-composite image, but the composite is much more informative.  Time3000 (talk) 15:58, 11 May 2008 (UTC)
 * Oppose. I agree with Time3000 on this. An example of thresholding could be created with a much better quality original image. Nautica Shad es  20:44, 11 May 2008 (UTC)
 * Oppose Really poor composition --Mike Spenard (talk) 04:23, 12 May 2008 (UTC)
 * Oppose per above comments Clegs (talk) 14:13, 12 May 2008 (UTC)
 * Comment - I think this might look better if it was done with something like a face. 8thstar 01:06, 13 May 2008 (UTC)
 * I agree. If it was done with a picture that had a little more color gradient in it, it would be a good example of thresholding. Clegs (talk) 19:18, 13 May 2008 (UTC)
