    Article Snippet: Although many methods for automated fluorescent-labeled cell detection have been proposed, not all of them assume a highly inhomogeneous background arising from complex biological structures.. Here, we propose an automated cell detection algorithm that accounts for and subtracts the inhomogeneous background by avoiding high-intensity pixels in the blur filtering calculation.. Cells were detected by intensity thresholding in the background-subtracted image, and the algorithm’s performance was tested on NeuNand c-Fos-stained images in the mouse prefrontal cortex and hippocampal dentate gyrus.
