Abstract
The embodiment of the invention provides a face image searching method and a device. The method comprises: according to face amount information, searching the face image conforming to the face amount information; and searching images in the searched face image conforming to the face amount information. The device comprises a first search unit and a second search unit. The embodiment of the invention searches the face image by combining face amount information and image content, thus overcoming the defect that image search in the prior art is not flexible or has low speed, and realizing flexible, quick and accurate face image search.
Description
Technical field
The embodiment of the invention relates to technical field of image processing, relates in particular to a kind of face image searching method and device.
Background technology
Along with electronic technology and Development of Multimedia Technology, people no longer are simple text messages to obtaining of information, begun to enter gradually new interpreting blueprints epoch, and search technique are in particular in the picture search in these epoch.And the picture search technology comparatively is widely used in facial image, promptly has the image of people's face, search.
Existing picture search technology mainly contains two classes: a class is to be undertaken by the search of the text message relevant with image, promptly artificially image file and text message file are bound, during search, in the text message file, search required text message, finally obtain image file with its binding by the text message file that finds.This method is the main flow mode of present network epigraph search.Another kind of picture search technology is based on the search of picture material, and for example the shape of object, personage's shape of face etc. are searched in the matching image.This way of search can accurately be carried out picture search.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: the image search method that adopts the text message relevant with image, owing to image file and text message file must be bound, thereby make search underaction, convenient and directly perceived; And the image search method that mates based on picture material, then the searching and computing amount is big, and retrieval rate is slow, can not satisfy the requirement of quick search.
Summary of the invention
The embodiment of the invention provides a kind of face image searching method and device, in order to solve picture search underaction or slow-footed defective in the prior art, realizes flexibly, face image searching fast, accurately.
The embodiment of the invention provides a kind of face image searching method, comprising:
According to people's face quantity information, search meets the facial image of described people's face quantity information;
In the facial image that meets described people's face quantity information that searches out, carry out picture search.
The embodiment of the invention provides a kind of face image searching device, comprising:
First search unit is used for according to people's face quantity information, and search meets the facial image of described people's face quantity information;
Second search unit is used for the facial image that meets described people's face quantity information that searches out at described first search unit, carries out picture search.
The face image searching method of the embodiment of the invention and device, by in conjunction with people's face quantity information and picture material, to carry out face image searching, overcome picture search underaction or slow-footed defective in the prior art, realized flexibly, face image searching fast, accurately.

In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply, apparently, accompanying drawing in describing below is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the process flow diagram of face image searching method one embodiment of the present invention;
Fig. 2 is the structural representation of inventor's face image search apparatus one embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 is the process flow diagram of face image searching method one embodiment of the present invention.As shown in Figure 1, the embodiment of the invention provides a kind of face image searching method, comprising:
Step 101, according to people's face quantity information, search meets the facial image of this people's face quantity information;
Step 102, in the facial image that meets this people's face quantity information that searches out, carry out picture search.
Face recognition technology is increasingly mature at present, in increasing electronic product, be widely used, comprise digital camera, smart mobile phone etc., by using the face recognition technology of software or hardware, when taking pictures, can identify the people's face in preview (photo preview) zone exactly, and obtain the number of people's face in the picture.The hunting zone of the face image searching method that the embodiment of the invention provides is applicable to the facial image that carries people's face quantity information by shootings such as digital camera or smart mobile phones, for example, people's face quantity information can be stored in the extended field of corresponding facial image.When carrying out picture search, at first import the people's face quantity in the target image, by people's face quantity of storing in the retrieving images file extent field, the image range of dwindling next step search effectively.And then in the facial image that meets this people's face quantity that searches out, further carry out picture search, for example, can carry out picture search, accurately to obtain target image based on picture material.
The face image searching method of the embodiment of the invention, by in conjunction with people's face quantity information and picture material, to carry out face image searching, overcome picture search underaction or slow-footed defective in the prior art, realized flexibly, face image searching fast, accurately.
