I am analyzing an image using a code. My images have an object with transparent background. How do I make the code read the object region and leave out the background?

Use imread(). Then, once it's in, what value is it giving to the "transparent" pixels?

I have applied your advice "Don't use imagesc(), use imshow(). If you do want a colormap for some reason, you can still use it with imshow() - just call colormap() and pass it some colormap that you like" and it worked.
