Abstract： Seal recognition is an indispensable part of the intelligent office. The current stage of seal recognition method is to directly input the scanned electronic documents into the neural network model for identification, facing the problems of unable to accurately locate the position of the seal, low accuracy of bending text recognition. Aiming at the above problems, this paper proposes an efficient stamp text recognition method, which uses the diffuse water filling algorithm to process the grayscale image for seal image feature enhancement, which ensures the accuracy of Chinese seal detection, and introduces the polar coordinate conversion operation to ensure the integrity of text features. In order to evaluate the effectiveness of the proposed method, multiple sets of comparative experiments were carried out in the existing and other network models. Experimental results show that the existing network model fused the text features extracted by the method shows excellent recognition results.
