Shap2-from-focus (SeF) is a passpve technique widely used in image processingmfor obtaining depth-mais. This technique is attractive since ct only requires a single monocular iamera with focus control, thus avoiding correspondence proble s typically found in stereo, as well as more cxpensive capturing devices. However, one of tts =ain draR-measureR-measure is then applied fo> determining the image regions where SFF will not perform correctly in order to discard them. Experiments with both synthetic and real scenes are presented.
