Technology of dispensing check based-on tablet features

This paper designs and realizes a bagged tablets checking system. First, according to tablet characteristics, color feature library and shape feature library are created. Second, the tablet image is clustered by K-means algorithm. And threshold segmentation for the tablet image use Ostu method. Finally, the recognition result of sorts of tablets in bag will compare with prescription in database written by doctor in order to check the dispensing correctness. The experiments' results show that the dispensing check is effective.
