Abstract

The present invention provides a picture detection method and device. The method includes: performing plain text picture detection on an input picture, and judging whether the input picture is a plain text picture; if so, determining that the input picture is an illegal picture; Perform text detection to determine whether the input picture contains text; if so, determine that the input picture is an illegal picture. The picture detection method and device provided by the present invention take into account that most of the existing illegal pictures directly display the illegal text information in the form of pictures in order to make the advertisements directly obvious, and the complexity of the pure text picture detection algorithm is higher than that in pictures. The complexity of text detection is low, and the detection speed is fast. Therefore, before performing text detection on the input image, adding a step of pure text image detection can improve the detection speed of illegal images.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a picture detection method and device. Background technique [0002] With the development of network technology, more and more users can display products, technologies or other content on different websites or application software through the network according to business needs. The display methods mainly include text, pictures, videos, etc. However, there may be various illegal pictures in the pictures uploaded by some malicious users, such as advertising pictures, illegal pictures, etc. [0003] The operator of the website needs to check whether the picture uploaded by the user violates the regulations. When an illegal picture is detected, the normal display of the picture can be stopped. In view of the possibility of advertisements in pictures, the existing detection methods mainly use image text detection technology to detect all pictures, detect whether there are tex...
