A method for synthesizing enhanced depth of field digital still camera pictures using multiple differently focused images is presented. This technique exploits only spatial image gradients in the initial decision process. The spatial gradient as a focus measure has been shown to be experimentally valid and theoretically sound under weak assumptions with respect to unimodality and monotonicity. 1 Subsequent majority filtering corroborates decisions with those of neighboring pixels, while the usedoi:10.1117/12.476754 fatcat:daxa42fhorejnl42cud6dcuwv4
