In this paper we propose a novel way of using time-of-flight camera depth and intensity images to produce a higher resolution depth image with prior knowledge of spatial noise distribution, which is correlated with the incident light falling on each pixel. The proposed method is compared to well-established methods, and results with real image data are presented.
