Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] refer to figure 1 , an embodiment of a method for tracking homologous pictures by watermarking is proposed in the present invention. The method can include:

[0056] Step S10, acquiring the picture feature value stored in the watermark of the current picture;

[0057] Step S11 , according to the feature value of the picture, search for a homologous picture matching the feature value of the picture in the database.

[0058]The above-mentioned method of tracking homologous pictures through watermarking can embed the picture feature value of the original source of the picture into the picture itself through digital watermarking technology, then when performing picture detection, the picture feature value can be quickly extracted from the picture watermark and compared The feature database performs image matchin...

Abstract

The invention discloses a method and a system for tracing a homologous image through a watermark. The method comprises the steps as follows: an image characteristic value stored in a watermark of a current image is acquired; and a homologous image matched with the image characteristic value is searched in a data base according to the image characteristic value. According to the method and the system, fault tolerance matching is performed by using the accurate characteristic value of the image, if the value can be matched with data in the data base, the image can be determined to a homologous image basically, the error rate is extremely low, and the accuracy is high; and the watermark of the image can also be used for performing tracing, the complexity of occurrence and reading of the watermark is smaller than that of the similarity identification; and the length of a characteristic string is far smaller than the similarity, so that the matching speed is higher.

Description

technical field [0001] The present invention relates to a homologous image tracking technology, in particular to a method and system for homologous image tracking through watermarking. Background technique [0002] Images of the same origin refer to images of the same source and their variants on the same platform. For example, after a picture is delivered to a certain platform, and then re-distributed through various variants such as format conversion, cutting, etc., these pictures belong to the same source picture. If the same scene is photographed or painted by different people, it does not belong to the same source picture. [0003] In the era of web 2.0, a large amount of data is generated by users. After a data source enters the Internet, it will produce variations due to the behavior of various users or systems during the dissemination process. For example, after a picture is placed on the Internet, it is easy to be compressed, cropped, formatted, added user inform...
