Abstract

Modern video cameras often only capture a single color per pixel in a single pass operation. This process is called ltering, where pixels are ltered through a color lter array, and the Bayer filter is perhaps the most common filter used today. This means that we must restore the missing color channels in the image or the video frame in a post-processing step, i.e., a process referred to as debayering. In a live video scenario, this operation must be performed eciently in order to output each video frame in real-time, while also yielding acceptable visual quality. Here, we evaluate debayering algorithms implemented on a GPU for real-time panoramic video recordings using multiple 2K-resolution cameras.
