[0033] The method for recovering shredder broken documents based on character features of the present invention firstly converts the broken Chinese documents into digital images, then extracts the broken documents through image preprocessing on the computer, and then extracts the broken documents according to the structural features of Chinese characters The documents are spliced together, so as to realize the automatic recovery of broken Chinese documents on the computer. Among them, the image digitization part is to convert paper broken document information into digital images through scanners and other equipment, so that it is not distorted and easy to calculate and process. The image preprocessing part enhances and extracts the fragmented image through histogram equalization, image filtering, image extraction and other means. The image splicing part establishes the correlation between different fragments according to the stroke structure characteristics of Chinese charac...
