Abstract
Various features for distinguishing strawberry shape were studied. Firstly, twelve features were proposed by the authors based on their past research findings and experience. Secondly, the statistical distribution of these features was examined. We then analyzed whether only one feature is enough or multiple features are required for distinction. Consequently, the statistical distribution of each feature for A and B grades showed two types: ones with inter-grade difference and ones without inter-grade difference. The former type also showed inter-species differences. It is considered that distinction cannot be made with any single feature, but requires a combination of more than one feature.
