Method for identifying image with watermark and identifying system

Abstract

The invention discloses a method for identifying an image with a watermark and an identifying system. The method includes the steps of selecting all candidate watermark areas of an image to be identified, identifying watermarks on each candidate watermark area through a deep convolution neural network classifier to determine whether the image to be identified is an image with a watermark, and realizing identification of images with watermarks. Lots of image training data can be conveniently and rapidly obtained, and a deep convolution neural network classifier is established through a convolution neural network algorithm via the image training data to solve the problem of insufficient training data in the prior art. The deep convolution neural network classifier established in the invention effectively simulate a visual processing system of human eyes, can identify local fine watermark texture, and effectively solves the problem of small area, light color and high transparent level of watermark in an image with a watermark. A process for identifying areas without watermarks can be reduced, the identification time is shortened, and identification efficiency is improved.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a watermarked image recognition method and recognition system. Background technique [0002] Images contain rich and intuitive information. At present, in the fields of social networking, shopping, and tourism on the Internet, a large number of images are needed to convey information to users. Due to the extremely fast and portable dissemination of Internet information, more and more individuals and organizations choose to embed watermark information in their own images, such as printing trademarks or website watermarks in some areas of the images, so as to protect the ownership of image information. Therefore, before using the image, the provider of the image information needs to review the image to identify whether the image contains watermark information, so as to avoid misuse and infringement. With the rapid development of the Internet, image providers use many channels such...
