Astronomical PST Image

The Phase Stretch Transform algorithm, as it is known, is a physics-inspired computational approach to processing images and information. The algorithm grew out of UCLA research on a technique called photonic time stretch, which has been used for ultrafast imaging and detecting cancer cells in blood. The algorithm also helps computers see features of objects that aren’t visible using standard imaging techniques. For example, it might be used to detect an LED lamp’s internal structure, which – using conventional techniques – would be obscured by the brightness of its light, and it can see distant stars that would normally be invisible in astronomical images. It is available for free download on two open source platforms, Github and Matlab File Exchange. Making it available as open source code will allow researchers to work together to study, use and improve the algorithm, and to freely modify and distribute it. It also will enable users to incorporate the technology into computer vision and pattern recognition applications and other image-processing applications. Please click here to read further.
