The modification consists of inserting a set of patterned color filters into the aperture of the camera lens. This work generalizes the previous research on a single-channel coded aperture, by deploying distinct filters in the three primary color channels, in order to cope better with the effect of a Bayer filter and to exploit the correlation among the channels. We derive the model and algorithms for the multi-channel coded aperture, comparing the simulated performance of the reconstruction algorithm against that of the original single-channel coded aperture. We also demonstrate a physical prototype, discussing the challenges arising from the use of multiple filters. We provide a comparison with the single-channel coded aperture in performance, and present results on several scenes of cluttered objects at various depths.","abstract_html":"This thesis describes the multi-channel coded-aperture photography, a modified camera system that can extract an all-focus image of the scene along with a depth estimate over the scene.
