Problems solved by technology

[0005] In order to overcome the defects and deficiencies in the prior art, the present invention proposes an off-line handwritten Chinese character recognition method with imitation feedback adjustment mechanism, in order to solve the problem of fixed cognitive method and misrecognition rate in the open-loop non-feedback cognitive system. High-level problems, so that people can freely adjust the cognitive method to carry out multi-layer feedback cognition, accurately classify and cognition the samples to be cognition, and significantly improve the cognition accuracy

Embodiment Construction

[0061] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present invention. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of this patent.

[0062] Embodiments of the present invention provide an off-line handwritten Chinese character recognition method with an imitation feedback adjustment mechanism to solve the defects and misrecognition rate in the prior art that the optimized feature space and classification recognition criteria are not updated once they are established higher question. Specifically, the steps are as follows:

Abstract

The invention discloses an off-line handwritten Chinese character recognition method having an imitated feedback adjustment mechanism. The method is characterized in that a first stage is acquisition of knowledge of recognition needs of a to-be-recognized sample set; a second stage is extraction of features of the samples to be recognized based on a selected recognition method; a third stage is training of an integrated pattern classifier optimal model; a fourth stage is fuzzy integral-based recognition fusion of recognition results under different recognition methods; and a fifth stage is recognition result evaluation, and the processes of the front four stages are reactivated according to judgment of the recognition results. The off-line handwritten Chinese character recognition method having the imitated feedback adjustment mechanism can realize differentiated treatment with different recognition methods according to different recognition needs of different samples when facing multi-category samples, and performs multi-level imitated feedback recognition on wrongly recognized samples according to credibility judgment of the recognition results, thereby remarkably improving recognition accuracy.

Description

technical field [0001] The invention belongs to the technical field of Chinese character cognition, and in particular relates to a cognition method integrated with multiple cognition methods with an imitation feedback adjustment mechanism. Background technique [0002] Chinese character recognition is an important research field of artificial intelligence, and it has been widely used in automatic bank signature recognition, teaching and office automation, and large text recognition and storage. At present, the research on the feature extraction method of handwritten Chinese characters has both academic papers that have done in-depth theoretical analysis on this, and engineering methods for practical applications, such as the invention patent "A Method for Image Feature Extraction for Handwritten Chinese Character Recognition" (CN101488182B ) and the invention patent application "A Method for Recognition of License Plate Chinese Characters Based on Multi-Feature Fusion" (CN10...
