Embodiment approach
[0143] In this embodiment, the handwriting trajectory can be collected from the handwriting board, and the coordinate sequence of each handwriting stroke in the handwriting trajectory is sequentially stored in a one-dimensional array. The handwritten trajectory collected each time contains several strokes, so the handwritten trajectory can be saved in a two-dimensional array, as shown in the following example; {{(93 198), (913 205)}, {(495 203), (470 847) ,(405 784)}}.
[0144] After obtaining the handwriting trajectory, a character segmentation operation can be performed on the handwriting trajectory, and the character segmentation can include a stroke pre-segmentation operation and a handwriting joint operation. The text segmentation method proposed in the following embodiments can improve the recognition efficiency of handwritten input.
[0145] The process of stroke pre-segmentation is as follows: When writing Chinese characters on the handwriting board, the default Chine...

The present application discloses an online handwritten character recognition method. The online handwritten character recognition method includes: obtaining the handwritten trajectory and determining the stroke coordinate sequence of each handwritten stroke in the handwritten trajectory; The handwriting track is carried out single-character segmentation, obtains single-character handwriting track; Determines the feature vector of described single-character handwriting track according to the feature point of each handwritten stroke in the single-character handwriting track; The feature vector of described single-character handwriting track is input to machine Learning a classification model to obtain the text content corresponding to the handwriting track. The application can improve the efficiency of handwritten character recognition and reduce the resource occupation of handwritten character recognition. The application also discloses an online handwritten character recognition device, an electronic device and a storage medium, which have the above beneficial effects.
Description
technical field [0001] The present application relates to the technical field of computer character recognition, in particular to an online handwritten character recognition method and device, an electronic device and a storage medium. Background technique [0002] With the popularity of electronic devices, handwritten character recognition is widely used in various devices. The process of handwritten character recognition includes: the user writes on the screen of the electronic device with a finger or a stylus, and the electronic device uses the internal recognition system to write The text is converted into a standard font recognizable by the electronic device and displayed on the screen. [0003] In the related technology, all contact points are converted into stroke strings including stroke number, stroke direction, stroke order and writing speed, and handwritten character recognition is realized according to the stroke strings. However, since the handwritten handwriti...
