Images, produced by a general-purpose imaging setup, are considered. The performance of the method has been evaluated with a test set of 245 images. The images typically contained between 10 and 70 colonies per dish, with relative coverage of the dish less than 10% of the area. The average counting error (missed colonies) on this set was under 4%. A tool, implementing the method, has been developed in Matlab. The tool provides a batch mode for processing of larger image sets prepared beforehand in the darkroom and it automates the process of counting as much as possible. It is available for download or can be requested from the authors of the paper, in both cases free on charge.
