How to add, how to subtract, and how to de-speckle

I present optimal methods for image co-addition and subtraction that have many advantages over existing methodologies. These methods are useful for many types of astronomical data analysis, beyond the field of image processing. Specifically, these techniques are optimal for any hypothesis testing or measurements, numerically stable and result in images which have uncorrelated noise. I will present these methods as well as their impact for deep surveys, transients search, and diffraction-limited imaging.
