Exact integral images at generic angles for 2D barcode detection
Using integral images for fast computation of sums of rectangular areas is very popular in computer vision. However the method does not extend naturally to rotations at arbitrary ...

A Theory of Catadioptric Image Formation
Conventional video cameras have limited elds of view which make them restrictive for certain applications in computational vision. A catadioptric sensor uses a combination of lens...
