Abstract
This paper describes a method for obtaining a composite focused image from a monocular image sequence. The image sequence is obtained using a novel non-frontal camera that has sensor elements at different distances from the lens. This paper first describes the motivation behind the non-frontal camera, followed by the description of an algorithm to obtain a focused image of a large scene. Large scenes are scenes that are deep and wide (panoramic). Consequently, the camera has to be panned in order to image all objects/surfaces of interest. The described algorithm integrates panning and generation of focused images. Results of experiments to generate extended depth of field images of wide scenes are also shown.
