TransiNet0 was the original implementation of TransiNet: an end-to-end image-generating astronomical transient detection which performs de-noising, PSF-matching, localization and detection all in a single go.
In this work the task of detection, and in particular detection of astronomical transients is looked at from a different angle. In the computer vision community, the term detection has almost always been equal to regressing bounding boxes around a potential target. In the astronomy community though it has usually meant classification of the potential targets which have already been localized which entails several pre-steps, including de-noising, PSF-matching, etc.
In TransiNet, the whole task is redefined as one of generating images which are blank everywhere except where the target is located — similar to a heat-map. TransiNet gave state-of-the-art results with extremely high degrees of purity and completeness.

Newer variants of TransiNet are being used as official packages of the LSST telescope.
