Method for studying distributed objects

A method for testing a plurality of distributed objects (1) using an overview image (200) of the area (2), in which the objects (1) are distributed, whereby • the overview image (200) into a binary image (210) is converted (110) by the intensity values ​​(202) of the pixels (201) of the overview image (200) are classified to (202a, 202b) whether a or beyond predetermined threshold (208) are located; • the binary image (210) to structures (219) are smaller than the objects (1), adjusted (120) so that an adjusted image (220) is formed; and the adjusted image (220) is morphologically closed (130), so that a binary object mask (230) is formed which indicates which locations of the region (2) to objects (1) include and which places the area (2) at any object type. A computer program product containing a machine-readable program comprising instructions which, when the program is executed on a computer it causes the computer and, if necessary, connected measuring apparatus to execute the method according to the invention.
