Do you know where I can get a sample of its use using commands in VB?
convert other.jpg -crop 100x100+300+400 crop.png
compare -metric RMSE master.jpg crop.png -subimage-search null:

No way to issue and get result using Dll in Visual Basic?

convert other.jpg -crop 100x100+100+100 crop.jpg

This command takes 90 seconds to complete, master.jpg is 640x480 24 bit, is the 24 bit the problem? if so how do i reduce?
compare -metric RMSE master.jpg crop.png -subimage-search null:

How would I issues these commands using the dll? or a script?

I found this at one of the links you suggested. (http://www.imagemagick.org/Usage/compare/#camera) I am getting an "average" difference for all the images and then if the individual difference is greater than the average difference I keep the image as it has something in it. How would I do this?

So would I need to resize my secondary images, then compare master image?

I have a master image and I want to compare to like images to see if the like image has moved left, right, up or down from the master. Is this possible with Imagemagick?

I'm using VB6 with COM DLL
