TL;DR: In this article, a method for combining stacks of images into a single summary image, referred to as a template, was proposed and compared with using pixelwise medians or means by various criteria.
Abstract: Large, multifrequency imaging surveys, such as the Large Synaptic Survey Telescope (LSST), need to do near-real-time analysis of very large data sets. This raises a host of statistical and computational problems for which standard methods do not work. In this article, we study a proposed method for combining stacks of images into a single summary image, sometimes referred to as a template. We evaluate this method by comparing it with using pixelwise medians or means by various criteria. Note that the goal is not to propose these comparison methods for use in their own right, but to ensure that additional complexity also provides substantially improved performance.
