Abstract

The invention discloses a novel digital extraction and identification method and a system thereof. The method comprises the following steps that a mobile electronic device identifies and processes handwritten digits through scanning; through an OSTU algorithm, a scanning result is changed into black and white; through a vertical projection segmentation algorithm, a series of digits are segmented into independent individuals; through an Hilditch algorithm or an ZS algorithm, the digits are refined; through bilinearity or a bicubic interpolation algorithm, a refined digital image is zoomed; through a rough grid characteristic extraction method, structure characteristic extraction is performed on the normalized digital image so as to generate a characteristic vector and input into a recognizer; a trained SVM recognizer is used to classify and identify the input characteristic vector so as to acquire an identification result of the digital image; and combining the single identification result to form a character string and output to a user interface. Through scanning, the handwritten digits are recorded into the electronic device, which is convenient for a next operation. The method and the system are convenient and rapid.

Description

technical field [0001] The invention belongs to the field of computer application technology, and in particular relates to a novel method and system for number extraction and recognition. Background technique [0002] The basic Arabic numerals have only ten digits, but they are written in different ways depending on who recognize them. As numerals used in various countries and regions all over the world, their writing has regional characteristics, and it is difficult to fully take into account the various writing methods of the world. [0003] When reading handwritten digital information, it may be difficult to read due to scribbled writing; and when the number string is too long, it needs to be read repeatedly to ensure the correctness of the information, which is time-consuming. Contents of the invention [0004] The purpose of the present invention is to provide a new method and system for digital extraction and recognition, aiming to solve the problem of reading handwr...
