Embodiment approach

[0073] In addition, the embodiments of the present application do not limit the implementation of the above-mentioned "image feature extraction sub-network", for example, any existing or future image feature extraction network (eg, CNN) can be used for implementation. For another example, in order to take into account the text recognition efficiency and text recognition accuracy, the embodiment of the present application also provides a possible implementation of the above-mentioned "image feature extraction sub-network", for example, it may specifically include: N feature extraction modules.

[0074] The above-mentioned "feature extraction module" has an image feature extraction function; and the embodiment of the present application does not limit the "feature extraction module". For the feature extraction effect, the above-mentioned "feature extraction module" may be a residual block (Residual Block). It should be noted that one residual block can include two CNNs.

Abstract

The invention discloses a text recognition method and related equipment thereof, and the method comprises the steps: inputting a to-be-recognized image into a pre-constructed text recognition model after the to-be-recognized image carrying noise information is obtained, and obtaining a text recognition result of the to-be-recognized image outputted by the text recognition model. Wherein the text recognition model comprises a feature extraction network, a recurrent neural network and a transcription layer. The feature extraction network is used for extracting image features of the image to be recognized and suppressing noise information carried by the image to be recognized. Therefore, since the feature extraction network has an image noise suppression function, the image features extracted by using the feature extraction network and aiming at the to-be-recognized image almost do not carry noise information, so that the adverse effect of the noise information carried by the to-be-recognized image on the text recognition process can be effectively reduced; therefore, the accuracy of the text recognition result of the to-be-recognized image can be effectively improved, and the text recognition effect can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a text recognition method and related equipment. Background technique [0002] Text recognition technology is a typical image processing technology; and the text recognition technology has a wide range of applications. Among them, the text recognition technology is used to recognize the character information in an image data. [0003] However, due to defects in some text recognition technologies, the text recognition effects of these text recognition technologies for some image data (eg, image data carrying noise information, etc.) are poor. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the present application provides a text recognition method and related equipment, which can improve the text recognition effect. [0005] In order to achieve the above purpose, the technical solutions provided in the embodiments of th...
