Abstract:

There are many connection areas in the binary section image of densely piled cigarettes, which makes it difficult to recognize and count the cigarette s. The method based on template, matching to recognize cigarettes features the incorrect location of the center of templat, and may cause inaccurate cou  nting. To solve this problem, this paper proposes a method of amending the counting result which is obtained by the recognition method based on template matching. The standard cigarette＇s geometry structure is similar to a circle, so the positional relationship of cigarettes is analyzed based on the th  heory of the positional relationship of circles, and then a balanced positional relationship is defined. The amending process inverts the non-balanced p  ositional relationship into the balanced positional relationship. After the amendment, the unwanted cigarettes are subtracted and then the counting resu  lt is amended.

Key words: （image recognition, counting, template matching, positional relationship）
