Software simulation of depth of field effects in video from small aperture cameras

This thesis proposes a technique for post processing digital video to introduce a simulated depth of field effect. Because the technique is implemented in software, it affords the user greater control over the parameters of the effect (such as the amount of defocus, aperture shape, and defocus plane) and allows the effect to be used even on hardware which would not typically allow for depth of field. In addition, because it is a completely post processing technique and requires no change in capture method or hardware, it can be used on any video and introduces no new costs. This thesis describes the technique, evaluates its performance on example videos, and proposes further work to improve the technique's reliability.
