Abstract

The invention discloses a method and system for recognizing texts in an image. The method comprises the steps: firstly extracting N text positioning regions in a to-be-recognized image through a textdetection model, and correspondingly obtaining N to-be-merged text positioning boxes; wherein each to-be-merged text positioning box is a region contour of a corresponding text positioning region in the to-be-identified image; according to the vertex coordinates of each to-be-merged text positioning box, merging all the to-be-merged text positioning boxes to obtain K to-be-detected text positioning boxes; wherein N > = K > = 1; based on the text recognition model, recognizing texts in all to-be-detected text positioning boxes to obtain to-be-detected texts; comparing the to-be-detected text with keywords in a preset violation keyword dictionary to obtain an recognition result corresponding to the to-be-identified image; according to the technical scheme, the accuracy and the recognition efficiency of text recognition in a complex image can be improved.

Description

technical field [0001] The invention relates to the technical field of text detection and recognition, in particular to a text recognition method and system in an image. Background technique [0002] Text serves as a bridge to transmit information between human beings, especially in today's rapid development of the Internet, the dissemination of text information in the form of images can be seen everywhere. However, the content information of images uploaded by users is uneven. If we only rely on human eyes to screen out illegal images from a large number of images, the workload will be heavy and the efficiency will be low. [0003] In the prior art, the text recognition of the image is carried out through the optical character recognition method. However, the existing optical character recognition method is suitable for recognizing the text in the regular scanned document, and is not suitable for the text recognition under the complex background of the image. , resulting i...
