Hi All,
I have an image which contains the following features buildings, cars, trees etc. I detected the buildings using the code DeltaE done by Image Analyst and would like to classify buildings in one common class. Is there any method/function to do that?
Thanks in advance,
Pugazh

You have to decide what constitutes a building. It may be the color but is there are other things that color then you'll have to add shape or other features. Maybe try the "SURF" algorithm - see wikipedia.

Yes, if you store the "mask" variable into a cell array:
caMask{mroi} = mask;
