Abstract

The embodiment of the invention discloses a method and device for desensitizing a document image, electronic equipment and a computer readable storage medium, and relates to the technical field of computer vision, deep learning and cloud computing. A specific embodiment of the method comprises the steps of obtaining a to-be-processed document image; determining a regional image with text featuresin the to-be-processed document image by utilizing a LOMO algorithm, and identifying text contents corresponding to the text features in the regional image by utilizing a CRNN model; and performing desensitization processing on the target sensitive information corresponding to the preset desensitization requirement in the text content to obtain a desensitized document image. According to the embodiment, the data representation form which can be processed by the desensitization processing is expanded, so that the document image which does not directly contain the text information can be desensitized well, and the LOMO algorithm and the CRNN model are used, so that the recognition accuracy is also improved.

Description

technical field [0001] The present application relates to the field of artificial intelligence, specifically to the technical fields of computer vision and deep learning, and in particular to a method, device, electronic device, and computer-readable storage medium for desensitizing document images. Background technique [0002] Desensitization technology is a technology to clear sensitive information in target data files, that is, to prevent many adverse consequences of leakage of this part of sensitive information by clearing sensitive information. [0003] Most of today's desensitization technologies are only applicable to text files with text as the direct form of data. Contents of the invention [0004] Embodiments of the present application provide a method, device, electronic device, and computer-readable storage medium for desensitizing a document image. [0005] In the first aspect, the embodiment of the present application proposes a method for desensitizing a d...
