Information retrieval method and system based on face image

Abstract

The invention discloses an information retrieval method and an information retrieval system based on face images. The information retrieval method and an information retrieval system based on face images are suitable for mobile terminals. The method comprises the following steps that: an image acquisition module obtains face snapshot data from the current application program of a mobile terminal; characteristic valve extraction is conducted to the face snapshot data acquired by the image acquisition module to obtain a characteristic valve vector; and the characteristic valve vector is transmitted to a data processing server for retrieval matching and a matching result is fed back to the mobile terminal. By conducting face recognition to stranger images or pictures in the application program of the mobile terminal through the mature face recognition technique and by matching the characteristic of face recognition with characteristic references which are stored in the data processing sever, retrieval information related to strangers can be provided and the relevant information of the strangers in the application program can be rapidly known by users. Moreover, the retrieval method has the advantages that the retrieval method is rapid and convenient, the accuracy is high, the operating method is highly humanized and the satisfaction expressed by the users at mobile phone operation is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for information retrieval by using a mobile phone. Background technique [0002] With the rapid development of the Internet, Internet-based data search has been widely used by people. A typical application is to submit the keywords to be searched to the search engine through the webpage, and the search engine server retrieves the relevant data information and returns the search results to the user. [0003] With the improvement of the intelligence level of mobile phones, the upgrading of operating systems, and the maturity of wireless communication technology, mobile phones are integrated with multiple functions such as taking pictures, browsing web pages, watching videos online, and viewing pictures. Due to the convenience of mobile phones, people prefer to use mobile phones to browse the web, watch game videos or search for information in their spare tim...

AI Technical Summary

Problems solved by technology

In this era of information explosion, when people browse pictures or watch videos, they often encounter unfamiliar image information of people. If they want to know more information about this person, they need to ask friends around them or conduct text searches, which is wasteful. users' time, and it is difficult to obtain ideal retrieval results

Since the character image data does not have the clear directionality of the text information, and cannot provide users with clear keywords for retrieval, the traditional information retrieval methods for mobile phones need to be further improved.
