BackgroundCorrector – a software program for fast and user‐friendly improvement of digital photomicrographs

DOI: 10.1111/j.1365-2559.2011.03901.x Sir: In a previous publication, we described an approach to correct uneven illumination and improper white balance of digital microscopic images by utilizing complementary background pictures (‘background correction’). Seven years ago, this approach was realized by using the freely available software program IMAGE ARITHMETIC. Although the quality of correction in this program is indisputable, its graphical user interface (GUI) proved to be uncomfortable in practice. Thus, we developed a new software program called BackgroundCorrector (Figure 1) that is superior to IMAGE ARITHMETIC in several respects: • Drag-and-drop functionality.
