Abstract:
Due to the complex glyph structure and many variants,the recognition of oracle characters have always been a important problem in relevant field. This paper proposes to use oracle radical as a component to establish a recognition method of oracle radical and oracle combined character,to improve the accuracy of oracle bone script recognition. Method 1:According to the characteristics of the oracle radical,we have selected the maximum extreme stable region(MSER)of the single radical from the oracle bone script,and then put it into the improved BN-LeNet model to recognize; Method 2:In view of the scarcity of oracle combined character,we have proposed an OraNet model that directly recognizes the oracle bone script character. Transfer learning was introduced into model training,so as to extract the high-level features of the oracle bone script,the fine-tuning strategy is implemented to achieve the feature aggregation of low-level representations and high-level representations. The experimental results show that the recognition rate of BN-LeNet network for oracle radical recognition is 96.24%,and the recognition rate of fine-tuned OraNet model for oracle combined character is 98.58%,which shows that considering the oracle bone script recognition from the perspective of oracle radical,higher recognition accuracy can be obtained,At the same time,we treat oracle bone script as a radical combination instead of whole-word,which enables the system to recognize unseen new oracle bone script,i.e.,zero-shot learning. so it has important application significance for Oracle research.
