The invention has the beneficial effects as follows: the present invention obtains cellphone subscriber's facial image by image recognition technology, and from facial image, extract the image expressive features, with the image expressive features as a comparison unit usually change mobile phone scene mode, thereby avoided the loaded down with trivial details of traditional button switch mobile phone contextual model, greatly simplify the operation that mobile phone scene mode switches, and promoted the interest of the intelligent and user operation of mobile phone.
Description of drawings
Fig. 1 is the flow chart of steps of mobile phone scene mode changing method of the present invention;
Fig. 2 is the functional-block diagram of mobile phone scene mode switched system of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment, but embodiments of the present invention are not limited to this.
Along with the raising of mobile intelligent level and the maturation of human face expression recognition technology, the present invention adopts the human face expression recognition technology to come mobile phone scene mode is arranged, thereby simplified the operation that mobile phone scene mode arranges, promote intellectuality and the Humanization Level of Municipal of mobile phone operation, and enriched the interest of operation.
With reference to Fig. 1, a kind of mobile phone scene mode changing method may further comprise the steps:
Step S10 opens the setting program that is used for the switch mobile phone contextual model;
For example, namely unlatching is for the setting program of switch mobile phone contextual model by power key or after button makes mobile phone enter the standby wakeup state arbitrarily for the user, and the setting of shortcut herein can be changed arbitrarily by the user.
Step S20, mobile phone is identified the current user's of mobile phone facial image by image capture module, and extracts the image expressive features from described facial image;
The facial image of mobile phone by camera Real-time Obtaining user, human face expression identification (Facial Expression Recognition, FER) herein specifically comprise the step of the detection of people's face and location, the feature extraction of image expression.After image capture module has obtained facial image by the detection of people's face and location technology, needing further the facial image data to be carried out bad point (point that sudden change occurs) removes, primitive character extraction and Feature Dimension Reduction, go disturb to process, to obtain favourable characteristic, improve efficient and accuracy that subsequent detection is judged.
The result of image expression feature extraction should possess following condition:
(1), the complete substantive characteristics of expressing human expression;
(2), remove the interfere information that noise, illumination and other and expression have nothing to do;
(3), data representation format compact, avoid too high dimension;
(4), the preferably property distinguished is arranged between the feature of different classes of expression.
Concrete image expression feature extracting method is well known to those skilled in the art, and does not repeat them here.
Step S30, the image expressive features of storing in the image expressive features that described mobile phone extracts and the characteristics of image storehouse compares;
Image expression in the characteristics of image storehouse is characterized as mobile phone and obtains by training, study, and described characteristics of image storehouse comprises at least two characteristics of image word banks, stores respectively the image expressive features corresponding to different mobile phone scene modes in each characteristics of image word bank.The foundation in characteristics of image storehouse specifically may further comprise the steps:
Mobile phone is identified mobile phone active user's facial image by image capture module, and extracts the image expressive features from described facial image;
Be the characteristics of image word bank corresponding with a certain mobile phone scene mode with the image expression characteristic storage of extracting, with as the Rule of judgment that this mobile phone scene mode is set.
In actual applications, the user can arrange the strong human face expression of interesting differentiation as image expressive features corresponding to characteristics of image word bank, for example image expressive features corresponding to facial expression that close of face is set to the mobile phone conference model, and image expressive features corresponding to the facial expression of putting out one's tongue is set to the outdoor pattern of mobile phone etc.
Image expressive features in the described characteristics of image storehouse both can copy from other equipment (such as other portable terminals or computer), also can adopt the mobile phone learning training to obtain.In order to guarantee that image expressive features in the characteristics of image storehouse reflects the feature of user's face-image as far as possible objectively, avoid the interference of the various different factors that occur in the shooting process, can in image is expressed one's feelings the feature learning process, under background as much as possible, take user's facial expression, and set up the image expressive features that stores in the characteristics of image storehouse according to the image expressive features of same facial expression under many groups background.
Step S40, the matching result of the image expressive features of storing in the image expressive features of extracting according to described mobile phone and the described characteristics of image storehouse arranges corresponding mobile phone scene mode.
The facial image that obtains by camera when mobile phone, when the image expressive features of certain characteristics of image word bank of storing in the image expressive features that obtains after the human face expression feature is picked up and the characteristics of image storehouse was complementary, then the contextual model of mobile phone was set to contextual model corresponding to this characteristics of image word bank.For example, the human face expression of taking when mobile phone is the facial expression that face closes, and is conference model with the mobile phone Lookup protocol then.Like this, the user can control automatically by abundant facial expression the contextual model of mobile phone, to have enriched the interest of user to mobile phone operation.
With reference to Fig. 2, the present invention also provides a kind of mobile phone scene mode switched system, and this mobile phone scene mode switched system comprises:
Contextual model arranges and starts module 10, is used for starting hand-set contextual model setting program;
Image capture module 20 is for the facial image that obtains the current user of mobile phone;
Characteristic extracting module 30 is used for extracting the image expressive features from the facial image that described image capture module 20 obtains;
Described characteristics of image storehouse 40 comprises at least two characteristics of image word banks, stores respectively the image expressive features corresponding to different mobile phone scene modes in each characteristics of image word bank.To realize by the switching of human face expression to the multiple mobile phone contextual model.
Described mobile phone scene mode switched system also comprises:
The present invention obtains cellphone subscriber's facial image by image recognition technology, and from facial image, extract the image expressive features, with the image expressive features as a comparison unit usually change mobile phone scene mode, thereby avoided the loaded down with trivial details of traditional button switch mobile phone contextual model, greatly simplify the operation that mobile phone scene mode switches, and promoted the interest of the intelligent and user operation of mobile phone.
More than be that better enforcement of the present invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art make all equivalent variations or replacement also can doing under the prerequisite of spirit of the present invention, the distortion that these are equal to or replace all is included in the application's claim limited range.
