Abstract
For surveillance of space purposes, algorithms were developed to automatically detect satellite streaks in astronomical images (Ref. 2 and 3). However, the performances of the algorithms for the background removal were not tested. This technical note contains a short analysis that proves that image backgrounds are adequately removed with the algorithms described in Ref. 2. It also contains an algorithm variation that makes it more reliable. The analysis of image residues shows that the residual background is fainter than the detection sensitivity threshold and does not affect the detection performance.
