What are spatial Transformations? Are Affine transformations also part of spatial transformations?

Surely a google search would have solved this? – Simon Hayward Nov 21 '12 at 10:18
I tried googling, but I couldn't find any site which actually explained what Spatial transformations are. For affine transformations, it was pretty clear here. – Malcolm X Nov 21 '12 at 10:54

Yes, they are. Spatial transformations as used in signal/image processing you mean?

Yes affine transformations are a special case of that. Top result here

I see, is there any definition available? This is what I can guess. It's just any transformation in 3D space. – Malcolm X Nov 21 '12 at 10:56
Did you read the pdf that is the top result on google? There are definitions of both spatial and affine transformations. Is this in the context of image processing? A transformation can happen in any number of dimensions. – Simon Hayward Nov 21 '12 at 11:04
Haha.. The definition was quite difficult to understand, will look again, thanks! – Malcolm X Nov 21 '12 at 11:05
Ok, cool well, I hope this helped. Yes the definitions are fairly general, that's a good thing, even though it makes it hard to get into at first :). There are some worked examples later on. – Simon Hayward Nov 21 '12 at 11:19
