Watch for change in image

[txturbo]

Is it possible to look at a section an image, say 100 X 100 pixels and detect a change in color? 

 

For example I have an application where I have a camera that looks at a process in a plasma chamber. Sometimes the process goes out of control and grows something that glows orange. This happens slowly and always in the same location. 

 

I would like to isolate the section of the image, X pixels by Y pixels and record the RGB value of each as a reference. If some % of the values change from the given reference set a flag. 

 

Is something like this possible? I know that a machine vision system does this sort of thing but I already have a camera running in DF and I would prefer to use DF.

Depends on how the image is coming in.  If its coming in as a bitmap in a DAQFactory array, then yes.  If its coming in as a jpeg, then no.
