More Information
Summary:The invention discloses a method and device for identifying handwritten form figures. The method for identifying the handwritten form figures includes the following steps: determining an image to be identified; determining at least three pixel features of a specific pixel in the image to be identified according to the gray level of the pixel; respectively determining corresponding covariance of the image to be identified according to the at least three pixel features of the specific pixel; respectively calculating the distance between each covariance of the image to be identified and a Lie group mean value which corresponds to each category of figure-type labels which are included in a preset training image set; respectively determining a figure-type label which corresponds to a minimum distance among a plurality of distances which are determined by each covariance of the image to be identified as a spare figure-type label; and determining the figure-type label with a largest number in the spare figure-type l
