Inscription rubbing-based calligraphy character segmentation and recognition method

Abstract

The invention provides an inscription rubbing-based calligraphy character segmentation and recognition method. The method comprises the following steps of 1, processing images in a training set; 2, pre-processing a training sample; 3, reading an image processed in the step 2 for model training, wherein a feature matrix MLH and a feature vector matrix Me are models trained according to rubbings; 4, conducting the word segmentation for the entire image, and segmenting calligraphy characters out of the image; 5, judging each character segmented in the step 4 belongs to which character in rubbings, obtaining a dimensionality reduction feature matrix MP of the image, calculating the similarity, calculating the distance Dist between MP and each row of MLH, and determining that characters in one row of MLH that is smallest in distance to be to-be-recognized characters. According to the technical scheme of the invention, the inscription rubbing-based calligraphy character segmentation and recognition method can effectively realize the segmentation of calligraphy characters, and is high in recognition accuracy and fast in recognition speed.

Description

technical field [0001] The invention relates to the field of image segmentation and recognition, in particular to a calligraphy segmentation and recognition method based on inscriptions. Background technique [0002] Brush calligraphy is one of the traditional Chinese calligraphy arts and one of the essence of Chinese traditional culture. Now, the country vigorously advocates the inheritance of the essence of Chinese traditional culture, and the practice of calligraphy has also been vigorously promoted in primary and secondary schools. According to the relevant regulations of the Ministry of Education, practicing calligraphy has become a compulsory course for primary school students, and at least one class hour per week is required to practice calligraphy, and many middle and high schools also offer elective courses in calligraphy for students to learn. However, the practice of brush calligraphy depends largely on the guidance of the teacher. This is a difficult problem tha...
