In cases in which there are zeros in the optical transfer function, display of the absolute
value of the Fourier transform of a blurred image may allow these zeros to be seen, if the …

Several techniques for use in a stereo vision system are described. These include a stereo
camera model solver, a high resolution stereo correlator for producing accurate matches …
