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] like figure 1 As shown, the image watermark automatic detection method of the present invention comprises the following steps:

[0045] Step 101, establishing a watermark pre-detection model;

[0046] Step 102, establishing a watermark re-identification model;

[0047] Step 103, combining the watermark pre-detection model and the watermark re-identification model to realize automatic detection of the image watermark.

[0048] Among them, such as figure 2 As shown, step 101 specifically includes the following steps:

[0049] Step 1011, establishing a first image data set with a watermark; specifically, in this embodiment, the first image with a watermark is obtained by batch generation through automatic machine processing;

[0050] Step 1012, training a watermark detector based on a deep convolutional neural networ...

Abstract

The invention discloses an automatic image watermark detection method. The method includes the following steps: S1, establishing a watermark pre-detection model; S2, establishing a watermark re-identification model; and S3, combining the watermark pre-detection model and the watermark re-identification model to realize automatic detection of an image watermark. According to the method, a detectedcandidate watermark region is re-identified, the candidate watermark region is re-identified through manually designing features of the watermark and training the binary model specifically judging whether the watermark exists, false detection of a watermark detector, which is based on a deep convolutional neural network, on of patterns which are similar to the watermark is reduced, and an accuracyrate of watermark detection is increased.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an image watermark automatic detection method. 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 watermarks in their images, such as putting trademarks or website watermarks in certain areas of the images, so as to protect the ownership of the images. Therefore, before using the image, the image provider needs to review the image to detect whether the image contains a watermark to avoid misuse and infringement. With the rapid development of the Internet, image providers use many channels to obtain a large amount of image information every day, and the amount has fa...
