Projection defocus analysis for scene capture and image display
2006
ACM SIGGRAPH 2006 Papers on - SIGGRAPH '06
In order to produce bright images, projectors have large apertures and hence narrow depths of field. In this paper, we present methods for robust scene capture and enhanced image display based on projection defocus analysis. We model a projector's defocus using a linear system. This model is used to develop a novel temporal defocus analysis method to recover depth at each camera pixel by estimating the parameters of its projection defocus kernel in frequency domain. Compared to most depth
