Abstract: According to the shape characteristics of garlic seeds, a model was developed to identify garlic seeds direction based on Visual C++6.0 software, in which the technology of digital image processing such as conversion, division and expansion was used. The results indicated that the direction of most garlic seeds could be greatly identified and the correct recognition rate reached 92%. The method provided a technique foundation for enhancing garlic seeder automatization．
