Handwriting trace recognition method and device for writing with writing brush

Abstract

The invention provides a handwriting trace recognition method and device applied to writing with a writing brush. The method comprises steps as follows: acquiring handwriting trace data produced in the process when handwriting input equipment is pressed for writing and released for writing stopping are acquired; the handwriting trace data are subjected to smooth processing and interpolation processing; corresponding angle change values of handwriting points in the processed handwriting trace data are detected, and the points with the angle change values exceeding threshold values are determined as feature points; the adjacent feature points are connected to obtain multiple stroke segments, and the multiple stroke segments are separated into main stroke segments and auxiliary stroke segments according to the lengths of the stroke segments; features of the corresponding stroke segments are determined according to the connection relation of the main stroke segments and the auxiliary stroke segments; the directions of the main stroke segments are determined according to a preset stroke segment eight-direction rule; the directions of the main stroke segments and the features of the stroke segments are compared with a stroke sample library established in advance, and strokes corresponding to the handwriting trace data are recognized. With the adoption of the handwriting trace recognition method and device, the handwriting trace accuracy is improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for recognizing a line of a brush applied to writing with a brush.
