  • Publication number: 20230245501
    Abstract: The present invention provides an offline handwriting individual recognition system and method. The method comprises: scanning the suspicious handwriting to obtain a first white light image and a first three-dimensional image, and scanning the sample handwriting to obtain a second white light image and a second three-dimensional image; pre-processing the first white light image and the second white light image to obtain a first pre-processed image and a second pre-processed image; extracting a first skeleton image and a second skeleton image from the first pre-processed image and the second pre-processed image; obtaining a first writing trajectory and a second writing trajectory according to the first skeleton image and the second skeleton image; extracting a first dynamic feature, a first three-dimensional feature, and a second dynamic feature, a second three-dimensional feature; processing to obtain a correlation coefficient, and obtaining an individual recognition result.
