Abstract

The invention provides a text detection method and device, electronic equipment and a storage medium. According to the embodiments of the invention, the method comprises the following steps of: performing feature extraction on a text image to obtain a feature image; processing the feature image by using a convolutional neural network to obtain the probability that pixel points in the text image belong to a text region; processing the feature image by using a sequence model to obtain a key point position of the text region in the text image; and determining a text region detection result of thetext image according to the probability that the pixel point belongs to the text region and the key point position of the text region. According to the text detection method and device, the electronic equipment and the storage medium of the embodiment of the invention, the anti-interference capability of the text detection method can be improved while the text detection speed is increased, so that the robustness of the text detection method is stronger.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to a text detection method, device, electronic equipment and storage medium. Background technique [0002] Text detection has a wide range of applications and is a precursor to many computer vision tasks. For example, computer vision tasks such as image search, text recognition, identity authentication, and visual navigation all require text detection as a pre-step. The main purpose of text detection is to locate text lines or characters in an image. The current popular text detection methods, such as text detection methods based on sliding windows or methods based on computing connected domains, etc., have the disadvantage of excessive calculation, which not only consumes a lot of computing resources, but also consumes a lot of time, which cannot meet the actual application scenarios. speed requirements. Contents of the invention [0003] The embodiment of t...
