Image comparison c#
<p>I am currently making a movement prediction application.
In a timer I take a screenshot, oh lets say every 50ms.</p>

<p>As soon as two screenshots have been made I want code to be able to compare the two images, and draw ontop of the changed pixels. After the pixels have been drawn on I want to be able to find chunks of the pixels that have been drawn that are 10x10 pixels. Find the location(center) of that chunk and store it as a string. After two strings have been stored I want to find the difference in location between those two strings, after the distance has been calculated I want to move the mouse to the second chunk + the difference in chunk location.</p>
