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.</abstract>   <abstract language="cze" primary="0">Odhad hloubkové mapy a současná slepá dekonvoluce ze dvou obrazů rozmazaných defokuzací. Defokuzace je modelovaná konvolucí s prostorově proměnou maskou, díky čemuž je algoritmus schopný pracovat s aberacemi v realných optických soustavách. Maska může být zadána analyticky nebo tabulkou vygenerovanou algoritmem užívajícím sledování paprsku.</abstract>  <action target="CST"> <ARLID>cav_un_auth*0213937</ARLID> <name>Computer Vision Winter Workshop 2006</name> <dates>06.02.2006-08.02.2006</dates> <place>Telč</place> <country>CZ</country>  </action>  <RIV>JD</RIV>    <reportyear>2007</reportyear>     <permalink>http://hdl.handle.net/11104/0131944</permalink>        <arlyear>2006</arlyear>       <unknown tag="mrcbU56"> CD-ROM 704 kB </unknown> <unknown tag="mrcbU63"> cav_un_epca*0076446 Proceedings of the Computer Vision Winter Workshop 2006.
