Embodiment
For the ease of those skilled in the art's understanding, the present invention is done further description below in conjunction with accompanying drawing.
A kind of group creating method of address list; Said address list is stored in portable terminal, and the contact field information in the address list database comprises the contact head image of picture format, and the group creating method of said address list is based on face recognition technology; Shown in accompanying drawing 1, its step is following:
Step 1 is chosen a group picture from the photograph album that is stored in portable terminal, utilize face recognition technology to remove to isolate personage's head portraits all in the group picture, and extracts characteristic generation face characteristic template;
Step 2 with the sign of isolated personage's head portrait as group member, is created a group in address list;
Step 3, the face characteristic template that generates with step 1 is reference, respectively the contact head image in the address list is carried out the coupling of search type comparison pattern, matees successful contact person and is added in this group;
Step 4, group creating is accomplished.
Said portable terminal can be mobile phone or electronic equipments such as PDA or panel computer, and is not limited to aforementioned mentioned portable terminal.In the present embodiment, said portable terminal is that example is launched narration with the mobile phone.
Along with the application of 3G technology more and more widely, present address book contact is generally all through the network auto-associating or a contact head image manually is set so that the contact person is discerned.Therefore can utilize face recognition technology; When needs add a group, directly select a group picture earlier, such as graduating photograph; Through this group picture of direct importing; And with the picture name of this group picture as group's name, all personage's head portraits in the group picture and the existing contact head image in the address list are mated, mate the adding in this group of successful contact person.Picture format is the form of Computer Storage picture, common formats stored bmp, jpg, tiff, gif, pcx, tga, exif, fpx, svg, psd, cdr, pcd, dxf, ufo, eps, ai, raw etc.
The face characteristic template of said step 1 is saved in the address list database after generating automatically.The face recognition technology of prior art is based on people's face feature, to the people's face image or the video flowing of input, judges at first whether it exists people's face; If there is people's face, then further extracts position, size and each main face organ's of each face positional information, and, further extract the identity characteristic that is contained in everyone face according to these information.The regional characteristics analysis algorithm that quilt extensively adopts in the face recognition technology; It has merged computer image processing technology and biostatistics principle in one; The principle of utilizing biostatistics is analyzed and is set up Mathematical Modeling extracting the portrait characteristic, i.e. the face characteristic template.
