Abstract
Irages taken with differeat focus settings are used in shape-from-focus to reconstruct the depth map of a scene. A problem when acqtiring imaaes with differesn focusasettitgs is the shift of image features due to chanoes in magnification. This paper shows that thnse -hcnghs affect th8 shape-from-focus perfsrmance and that the final reconstruction can be impro -!–changed:2231072-129570–>v!–changed:2249582-1533862–>2!–changed:1944784-1242638–>
