Embodiment Construction

[0023] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are given only to enable those skilled in the art to better understand and implement the present invention, rather than to limit the scope of the present invention in any way.

[0024] As mentioned above, statistical analysis shows that: in a photo album of a social network, most of the faces contained in the image are the faces of the owner of the photo album. In other words, the frequency and number of times the album owner's face appears in the images of the album dominates compared to other people. Based on this fact, according to an embodiment of the invention, the face that is dominant in number or frequency in the photo album is considered to be the face of the photo album owner and is thus associated therewith. In this way, the face training data of the user can be effectively collected. By pe...

Abstract

The embodiment of the invention relates to a method and device for processing faces contained in images. The invention specifically discloses a method for processing faces contained in images, and the method comprises the following steps: aiming at each one of at least a photo album of a social network, detecting faces contained in images of the photo album; gathering the detected faces so as to generate at least a face data set; and selecting a face data set to associate with an owner of the photo album from the at least a face data set. The method also comprises the steps of establishing a face classifier for face recognition through learning based on the face data set associated with the owner of the photo album. The embodiment of the invention also discloses a corresponding device. According to the embodiment of the invention, the cost of face recognition of massive amounts of images is effectively reduced, and the efficiency is improved.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of information technology, and more particularly, to methods and devices for processing faces contained in images. Background technique [0002] With the continuous development of image capture technology and tools, a large amount of information is generated in the form of images every day. Many of these images contain identity information and / or social information. Extracting facial information from these images and determining the corresponding identity information is an important class of applications, which has great value in many fields such as social networking, national security, justice, finance, and human-computer interaction. Reasonable analysis and utilization of identity information of objects in images can provide users with better services and experiences. [0003] In general, facial information can be extracted from an image and corresponding identity information can be...
