Description: Circle seals and Ellipse seals:Based on the results of the circle and ellipse seals title detection in task1, PCA technology was used to correct the rotated seal, the image processing technology was used to separate the seal title, and finally the curved text was sent to the recognition model for recognition. The recognition model was selected by Trocr, and the training data includes the provided training data and synthetic data.
Rectangle seals and Triangle seals: rectangle seals and triangle seals were not based on the task1 detection model, but train a text line detection model. the image processing technology was used to separate the seal title. The recognition model was selected by Trocr, and the training data includes the provided by synthetic data.
