Abstract

The invention relates to a handwriting form identification method and device. The method comprises the steps of detecting a form line; determining a longest vertical form line and a longest horizontal form line which are crossed; calculating a boundary rectangle just covering all form lines; for each form line, extending the form line on the boundary rectangle to obtain a corresponding virtual form line; calculating the position of a central point of a frame defined by the virtual form line and the form line; dividing each central point into an internal point and an external point, wherein the internal point is the central point surrounded by the form line; grouping internal points, and if a path between the adjacent internal points is not blocked by the form line, determining that the internal points belong to a same group; combining frames corresponding to the internal points of the same group to form a cell; and identifying handwriting contents in each cell. According to the handwriting form identification method and device provided by embodiments of the invention, a handwriting form can be identified with high efficiency and high accuracy.

Description

technical field [0001] The present invention relates to a handwritten form recognition technology, and more particularly, to a handwritten form recognition method and equipment, which can efficiently and accurately identify a handwritten form and extract the content therein. Background technique [0002] With the development of information technology, the use of electronic devices (eg, personal digital assistants, handheld computers, mobile phones) and the like has become more and more popular in people's lives. The input methods of these electronic devices can be roughly divided into two categories: keyboard input and handwriting input. The keyboard input method adopts a keyboard on the electronic device, and the user clicks each key on the keyboard to perform input. In the handwriting input mode, the user's input is received through the touch screen of the electronic device, and the input is processed to identify the content input by the user. This requires that the elec...
