Embodiment Construction

[0043] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0044] Such as figure 1 As shown, a watermarked image recognition system includes: an acquisition unit 1 , a training unit 2 , a selection unit 3 and a recognition unit 4 . Wherein, the training unit 2 is respectively connected with the acquisition unit 1 , the selection unit 3 and the recognition unit 4 .

[0045] In the present invention, the acquisition unit 1 is used to generate image training data. The training unit 2 acquires image training data and establishes a deep convolutional neural network classifier. The selection unit 3 selects all watermark candidate areas of the image to be recognized, and inputs the image data of each watermark candidate area into a deep convolutional neural network classifier. The identification unit 4, as a watermark determination module, obtains all the probability vectors output by the...

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...
