Abstract

The invention provides a natural scene picture character recognition method based on deep learning. The natural scene picture character recognition method based on deep learning comprises the following steps of S1, establishing a character image database, and classifying the character image database; S2, carrying out image collection through an image collector, and carrying out preprocessing on the collected image; S3, performing feature extraction on the preprocessed image by using a deep neural network, and classifying the extracted features through a statistical classifier; and S4, carryingout auxiliary training by using a template matching method by using the artificial design characteristics. The invention provides the natural scene picture character recognition method based on deeplearning. Through the contrast processing, anti-noise processing and amplification separation processing, the contrast improvement effect of the image is better, so that the image has higher quality,the recognition rate of the image can be effectively improved, the influence of the external environmental factors on the image is reduced, and the feature extraction rate of the image is effectivelyimproved.

Description

technical field [0001] The present invention relates to the field of character recognition, in particular to a deep learning-based character recognition method for natural scene pictures. Background technique [0002] Text recognition technology is an important field of pattern recognition applications. In the 1950s, general text recognition methods were discussed, and optical character recognizers were developed. In the 1960s, practical machines using magnetic ink and special fonts appeared. In the late 1960s, there appeared A variety of fonts and handwritten character recognition machines, but the recognition accuracy and machine performance are not ideal. In the 1970s, it mainly studied the basic theory of character recognition and developed high-performance character recognition machines, and focused on the research of Chinese character recognition. Today's characters Recognition technology has improved a lot. [0003] The current deep learning-based text recognition me...
