Abstract
This paper describes the application of a new Spatial-Domain Convolution/ Deconvolution transform(S transform) for determining distance of objects and rapid autofocusing of camera systems usingimage defocus. The method known as STMAP involves simple local operations on only two imagestaken with dierent aperture diameters and can be easily implemented in parallel. Both images canbe arbitrarily blurred and neither of them needs to be a focused image taken with a pin-hole camera.STMAP has...Keywords
