I have recently started working of image processing with matlab on a project related to corrosion. Well, I have obtained pictures of the corroded aluminium plate at different times using specific corrosion environment and solution. Here is the question !!! How can I use Matlab program to identify the difference between pictures taken at different time. With the naked eye, some corrosion growth can be seen but how can that difference be represented using Image processing in Matlab. My target here is to find how the corrosion is growing with respect to time. Any help regarding this subject matter would be highly appreciated....

You can use this demo page as a starter. The sections 'Measuring Image Features' contains examples that sound useful in the context of your application.

Once you've segmented your regions of corrosion, the function REGIONPROPS will be quite useful!
