Problems solved by technology

[0003] However, the above-mentioned first method requires character-level annotation, that is, the position and information of each character on the input image needs to be marked, and the labor cost is extremely high; the recognition result of the above-mentioned second method is inaccurate, and multiple recognition or omissions often occur. The case of character recognition

Abstract

The invention relates to a text recognition method and device, equipment and a medium. The method comprises the steps that a to-be-recognized text image is acquired; the text image is converted into a target one-dimensional tensor through a Hilbert curve, and the target one-dimensional tensor is used for representing the sequence relation between pixels in the text image; and the target one-dimensional tensor is input into a pre-trained recognition network for text recognition to obtain a target character string in the text image. The text recognition cost can be reduced, the text recognition efficiency can be improved, and the text recognition difficulty can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a text recognition method, device, equipment and medium. Background technique [0002] Text detection and recognition techniques are widely used in computer vision tasks. In this technique, natural scene text recognition refers to the process of recognizing a sequence of characters in an image containing text. Since text consists of a variable number of characters, natural scene text recognition needs to recognize sequences of variable length from images. At present, there are two main schemes. One is based on a bottom-up strategy, which splits the text recognition process into three processes: character detection, character recognition, and character combination; the other is a strategy based on overall analysis, which first divides the image Encode, and then decode the sequence to get the whole string directly. [0003] However, the above-mentioned firs...
