the desiccant is widely used and plays an important role in the daily life and industrial manufacturing. ironically its package quality check is still a challenging issue. in this paper we present a new method for desiccant package quality check. first, the package lie on the assembly line in arbitrarily direction corrected to vertical direction. then the colicor information is used to distinguish the contaminated package. finally, we combine the texture analysis and region growth to obtain the detection result. the experimental results show the effectiveness of the proposed method and the detection accuracy can achieve 92.85%. © springer international publishing ag 2017.
