It should be noted that having there is the scene classification algorithm of many maturations in the prior art, therefore it will not be repeated here.
Further, the Second processing module 24, be additionally operable to the viewfinder image and any one virtual erect-position and The classification results of the affiliated scene of viewfinder image are input in default aesthetic evaluation model carries out U.S. to the virtual erect-position Scoring is learned, several described virtual erect-positions of traversal obtain several aesthetics scorings.
Specifically, the default aesthetic evaluation model is obtained by training, the machine learning method used includes convolution Neutral net, limited Boltzmann machine, depth confidence network etc..
It is used as another embodiment of apparatus of the present invention embodiment, in addition to reminding module, the reminding module, for working as When the aesthetics scoring for stating several virtual erect-positions is respectively less than lowest threshold, user is pointed out to adjust position of finding a view.
It is used as another embodiment of apparatus of the present invention embodiment, in addition to model training module.
The model training module is used for:
Obtain several images of known aesthetics scoring and personage's erect-position information;
Default aesthetic evaluation model is instructed using several images of known aesthetics scoring and personage's erect-position information Practice, or using the scene tag belonging to several images and image of known aesthetics scoring and personage's erect-position information to default Aesthetic evaluation model is trained, the aesthetic evaluation model after being trained.
Take pictures in real time guidance method and the system of the present invention, has the advantages that:
1st, using scene classification algorithm different scenes are carried out with adaptive aesthetic evaluation, and avoids taking general aesthetics The classification performance limitation of identification tactic, improves the accuracy of final erect-position recommendation of taking pictures.
2nd, aesthetic evaluation model is obtained by training, it is to avoid the subjectivity and one-sidedness of artificial rule model.
3rd, the present invention supports horizontal and vertical exposal model, can recommend a variety of optimal shooting erect-positions, voluntarily be selected for user Select.
For the more detailed explanation embodiment of the present invention, example 1 is provided, example 1 comprises the following steps:
Step S1:Into after exposal model, smart machine obtains current viewfinder image.
Step S2:Scene of taking pictures is recognized using image scene classification algorithm, photo is divided into by landscape according to recognition result, built Build two classifications.
Step S3:By the classification results of viewfinder image and the affiliated scene of some virtual erect-position information and the viewfinder image As input, the optimal erect-position information of people is calculated using convolutional neural networks aesthetic evaluation model.
Step S4:Smart machine goes out optimal erect-position prompting mark in the interface display of finding a view of taking pictures, and user instructs according to prompting The person of being taken shift position.If user is unsatisfied with optimal erect-position, interface provides handoff options, shows that other recommend erect-position;If no In the presence of erect-position is recommended, interface prompt user needs adjustment to find a view position.
In the step S1, into after exposal model, smart machine obtains current viewfinder image.
In the step S2, graphic collection can be landscape, building two by the result gone out according to scene classification Algorithm Analysis Individual classification, that is, obtain the affiliated scene classification result of photo.
It should be noted that having there is the scene classification algorithm of many maturations in the prior art, therefore it will not be repeated here.
In the step S3, by viewfinder image and the affiliated scene of some virtual erect-position information and the viewfinder image Classification results calculate the optimal group photo positional information of people using convolutional neural networks aesthetic evaluation model as input.Volume Product neutral net aesthetic evaluation model is obtained by training, it is to avoid the subjectivity and one-sidedness of artificial rule model.
It should be noted that aesthetic evaluation model includes being not limited to use convolutional neural networks, other machines can be also used Device learning method, for example, be limited Boltzmann machine, depth confidence network.
In the step S4, smart machine shows optimal erect-position prompting mark, user in the preview interface of finding a view of taking pictures According to the prompting guidance person of being taken shift position.If user is unsatisfied with optimal erect-position, interface provides handoff options, shows that other are pushed away Recommend erect-position;If in the absence of erect-position is recommended, interface prompt user needs adjustment to find a view position.
Specifically, the smart machine includes being not limited to PC, smart mobile phone, tablet personal computer, intelligent glasses, with And other have the equipment of camera and data processing function.Scene classification result can be used as convolutional neural networks aesthetic evaluation The input parameter of model, can also use and individually set up its corresponding convolutional neural networks aesthetic evaluation for each scene classification Model.Preview interface prompts for graphical cues and/or text prompt and/or voice message.Other recommend erect-position information be Other the virtual erect-position information chosen successively from high to low by aesthetics scoring.It is aesthstic appraisal result in the absence of optimal erect-position information It is unsatisfactory for lowest threshold requirement.
The embodiment of the present invention can be realized recommends the people's erect-position that is taken automatically, and carries out scene point to viewfinder image in advance Class, the accuracy that lifting erect-position is recommended;The convolutional neural networks aesthetic evaluation model obtained using training, it is to avoid artificial rule mould The subjectivity and one-sidedness of type;Horizontal and vertical exposal model is supported, multiple optimal shooting erect-positions can be recommended, for user voluntarily Selection.The scope that this method and system can be applicable is wide, can be generally applicable in smart machine.
Embodiments of the invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made, Equivalent substitution, improvement etc., should be included within scope of the presently claimed invention.
