Hello everybody!

I'm have a problem with 3D image comparison, my lecturer asked us to make a application that compare 2 3D images. But I don't know where to start. Could anybody let me know what step to research the processing, and give some information about what books should i read?

Thanks!

You have to clarify some aspect of the nature of the problem.

An "image" (in common sense) is 2D (it can be a projection of a 3D scene), but a 3D image shuld be (for extension) a "cube of pixel". Is that what you mean? Do you have to compare two "cube of pixels", or just two view of a 3D scene?

Then, what does "compare" actually mean?
- Compare to look if they "are" the same (two identical copies).
- Compare to look if they "look" the same (apart trivial transformation, like clipping / shifting / rotating etc.)
- Compare to look if they "represent" a same scene / physical object

Good questions. I first intuitively assumed 2D-images of 3D-objects, but then why mention it at all, that's what most images are!
