Odhad hloubkové mapy a současná slepá dekonvoluce obrazů rozmazaných defokuzací
 Šorel, Michal ; Flusser, Jan
We present an algorithm that uses two or more defocused images of the same scene for recovery of scene structure and simultaneous restoration of sharp image. Defocousation is modeled by convolution with arbitrary known spatially-variant mask unlike the vast majority of published algorithms that used cylindrical or Gaussian masks. In this way it is able to deal with aberrations present in real optical systems. The mask can be given analytically ro by a table or a ray tracing algorithm.
