... omdetect (omdetect-5.14.2) [?? Meta Index / Home Page / Algorithm Omdetect will find sources on an image using both a peak-finding and connected-pixel algorithm. The former will mainly detect ``point'' sources and the latter ``extended'' sources. The peak-finding algorithm is used first to try to locate all point sources, in order of decreasing brightness. This algorithm mainly overcomes problems with modular-8 patterns around bright sources and scattered light features. ...
