Abstract
In this paper, we present a new method that views offline handwritten chinese character recognition (HCCR) as a Re-identification (ReID) task. We introduce a print dataset as the target that needs to be retrieved, and make the test set of offline HCCR as the object of interest. According to ReID’s scene, the goal is to find the most similar print sample as the prediction result for each object of interest. We also employ triplet loss for metric learning, and train model together with cross-entropy loss, which has a good effect on improving performance. Compared with the classification model, the experimental results show that our method achieves much better results in few-shot learning, whose dataset is randomly selected from overall datasets. When the training set used is 5% of HWDB1.1, the gap between them even reached 9.8%. At the same time, it also obtains an accuracy of 97.69% on ICDAR-2013 offline HCCR competition dataset.
