Embodiment Construction

[0053] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0054] At present, handwriting recognition mostly uses handwriting trajectory sequence features to perform text recognition to obtain recognition results. For example, input handwriting trajectory sequence features into the trained text recognition model to obtain recognition results.

[0055] For the above method, in the free writing mode, such as vertical writing or oblique writing, due to ...

Abstract

The invention provides a handwriting recognition method and device, electronic equipment and a storage medium, and the method comprises the steps: determining a target character height for normalizing the height of each handwritten character in a handwriting track sequence based on a preset handwriting mode and the handwriting track sequence; normalizing the height of each handwritten character to a target character height to obtain a regular track sequence; and carrying out handwriting recognition based on the regular track sequence. According to the handwriting recognition method and device, the electronic equipment and the storage medium provided by the invention, the handwritten characters in various handwriting modes can be adjusted to the uniform target character height, and the problem that the handwriting recognition precision is influenced by different heights of the handwritten characters is avoided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a handwriting recognition method, device, electronic equipment and storage medium. Background technique [0002] As a simple, convenient and efficient input method, handwriting recognition has changed the traditional keyboard mode based on complex coding or pinyin input, and provided convenient conditions for natural human-computer interaction. [0003] At present, handwriting recognition mostly uses the features of the handwriting trajectory sequence to perform text recognition to obtain recognition results. However, when this method is applied in the free writing mode, since each handwritten character is written arbitrarily in the handwritten area, and the size of each handwritten character is different, the accuracy of the recognition result is low. Contents of the invention [0004] The invention provides a handwriting recognition method, device, electronic equipm...
