scan LCD screen and check for bad pixels

[Yesh]

I was wondering how should I solve this problem. I want to take a screen shot of an LCD screen

and scan through the LCD screen display and see if there are any bad pixels on the screen. I donot

know where to start. If anyone has implemented such algorithm or atleast have any good ideas.

I have Vision developement suite as well vision developement module with vision builder too.

By screen-shot you mean take a picture with a camera, a screenshot is not going to help much!

I have limited vision experience, but I think you may struggle to identify individual defective pixels without some super-expensive camera setup.

Posting this question on the machine vision forum may help.
