Fig. 2 is the flow chart of image processing method in one embodiment.As shown in Fig. 2, the image processing method includes step
Rapid 202 to step 208.Wherein：
Step 202, the image collection for including at least one pending image is obtained.
Image collection refers to the set being made of one or more pending image, and pending image can pass through electronics
What the camera of equipment obtained, can also be to be obtained from other electronic equipments, can also be and is downloaded by network, herein
It does not limit.For example, can install camera on electronic equipment, electronic equipment is referred to when detecting shooting instruction by shooting
Control camera is enabled to acquire pending image.Electronic equipment can immediately be handled image after getting image,
Image can also be uniformly stored in a file, in this document folder the image that stores reach certain amount and then
The image of storage is uniformly handled.Electronic equipment can store the image of acquisition into photograph album, when what is stored in photograph album
When image is more than certain amount, triggering handles the image in photograph album.
Step 204, the pending image in image collection is traversed, pending image is identified to obtain image classification mark
Label.
In one embodiment, it after electronic equipment gets image collection, can traverse pending in image collection
Image is successively handled pending image.Image classification label can be used for the classification of the photographed scene of tag image, treat
Processing image is identified to obtain image classification label, can be specifically that the background area of image is identified, obtain image
Tag along sort.
It is understood that generally all containing multiple objects in the scene of shooting image.For example, shooting outdoor scene
When, it can include generally pedestrian, blue sky, sandy beach, building etc. in image, when shooting indoor scene, generally can in image
Including the objects such as furniture appliance, office appliance.Generally may include foreground target and background area, foreground mesh in pending image
Mark refers to subject goal more outstanding in image, is the object that user compares concern, and background area refers to that foreground is removed in image
Region except target.
Electronic equipment can be detected the background area in pending image, detect that background area identifies the back of the body later
Which scene classification is scene area particularly belong to.Electronic equipment can pre-set the scene classification of background area, then pass through
Which preset scene classification preset sorting algorithm identification background area particularly belongs to.For example, can be by background area point
For scenes such as seabeach, snow scenes, night scene, blue sky, interiors, after background area is identified, it is corresponding background area can be obtained
Scene classification.According to the recognition result of background area, so that it may to obtain the image classification label of pending image.
Pending image in image collection can carry out uniquely tagged by image identification, obtain the figure of pending image
It, thus can be according to this as after tag along sort, the correspondence between image identification and image classification label can be established
Correspondence determines the corresponding scene classification of each pending image.For example, the image identification of pending image is " Pic_01 ",
Corresponding image classification label is " snow scenes ", is shot then being assured that image " Pic_01 " is write in snow scenes.
Step 206, the amount of images for counting the corresponding pending image of each image classification label, according to amount of images from
Target image tag along sort is obtained in image classification label.
After each pending image in image collection is identified, each image classification mark can be counted
Sign the amount of images of corresponding pending image.The more image classification label of correspondence image quantity, illustrates that user compares deviation
It is shot under the corresponding scene of image classification label.Target image point is obtained from image classification label according to amount of images
Class label, target image tag along sort can reflect the shooting custom of user, then can be according to target image tag along sort
To determine the association attributes of user.For example, image classification label of the amount of images more than first threshold can be obtained as first
Target image tag along sort, amount of images less than second threshold image classification label as the second target image tag along sort,
First threshold is more than second threshold.So first object image classification label can reflect that user compares the shooting field of preference
Scape, the second target image tag along sort can reflect the fewer photographed scene of user.
Step 208, target user's attribute is obtained according to target image tag along sort.
In embodiment provided by the present application, user property can be, but not limited to be that age, occupation, gender, hobby etc. can
Indicate the parameter of user's habit and build-in attribute.Target image tag along sort can reflect the shooting custom of user, therefore can be with
The attribute of user is predicted according to target image tag along sort.For example, the most image classification label of amount of images can be obtained
As target image tag along sort, according to the most image classification label, that is, target image tag along sort of the amount of images
The scene that identification user often shoots, to predict the user belongs to which age bracket and gender.
The image processing method that above-described embodiment provides, can be identified pending image, obtain reflection image and clap
Take the photograph the image classification label of scene.According to the quantity of the corresponding pending image of image classification label, target image classification is obtained
Label can predict the association attributes of user according to target image tag along sort.It can be accurate according to target image tag along sort
Supposition user shooting custom, to predict the association attributes of user, improve the accuracy of image procossing.
Fig. 3 is the flow chart of image processing method in another embodiment.As shown in figure 3, the image processing method includes
Step 302 is to step 314.Wherein：
Step 302, the image collection for including at least one pending image is obtained.
In one embodiment, according to the pending image prediction user property in image collection, general pending image
Quantity it is more, the accuracy for the user property predicted is higher.However the number for the pending image for including in image collection
Amount is more, bigger to the memory consumed when image procossing, takes also long.Electronic equipment to image handled when
It waits, can be automatic trigger, can also be that user triggers manually.The condition that an automatic trigger can be preset, works as satisfaction
When automatic trigger condition, step 302 is executed.For example, when the quantity of newer image in electronic equipment reaches preset quantity, open
The image for beginning to obtain storage generates image collection, and starts to handle image.Or when not reaching given time, start
It obtains and handles image collection.
Since the image of electronic equipment storage may be by what different modes obtained, for instance it can be possible that user is by taking the photograph
As head is shot, it may be possible to be downloaded on network, it is also possible to what good friend sent.And the image that the mode such as screenshotss generates
In, it is understood that there may be the more image that can not reflect the photographed scene for generating image is difficult to the shooting of reflection user in this way
Custom, is difficult to accurately predict user property.So when generating image collection, it can not have to obtain in electronic equipment
All images of storage, and only fetching portion image is handled.Step 302 is particularly as may include：From preset file
At least pending image that path obtains, and image collection is generated according to the pending image of acquisition.Preset file road
Diameter can only store user by taking the photograph for storing in the image that can be used for accurately identifying user property, such as preset file path
The image shot as head.
Step 304, the pending image in image collection is traversed, detects the foreground target in pending image, and obtain
The corresponding target area of foreground target.
After being detected to the foreground target in pending image, foreground target can waited locating by rectangle frame
Shared region in reason image is marked, and can also be directly marked by the edge of foreground target.Pending image
It is the two-dimensional pixel matrix being made of several pixels, electronic equipment can examine the foreground target in pending image
It surveys, the foreground target detected is made of pixel some or all of in pending image.Detecting foreground target
Later, the quantity for the pixel for including in foreground target can be counted.Target area can be by the picture that includes in foreground target
Vegetarian refreshments quantity is indicated, and can also use the pixel for including in the pixel quantity for including in foreground target and pending image
The ratio of quantity is indicated.In general, the pixel quantity for including in foreground target is more, corresponding region area is bigger.
It, may be from pending when carrying out target detection to pending image in embodiment provided by the present application
Multiple foreground targets are detected in image.When detecting two or more foreground targets, it is multiple that this can be obtained
The gross area shared by foreground target as target area, can also using the corresponding maximum area of foreground target as target area,
Herein without limiting.Target area is bigger, it is believed that the area that foreground target accounts for is bigger, correspondingly the area shared by background area
With regard to smaller, identify that the accuracy rate of image type is lower by background area in this way.
Pending image is a two-dimensional picture element matrix, then electronic equipment can establish one according to pending image
A two-dimensional coordinate system can indicate specific location of the pixel in pending image by two-dimensional coordinate.For example, can be to wait for
The pixel in the processing image most lower left corner is that coordinate origin establishes coordinate system, often moves up a pixel, the corresponding longitudinal axis
Coordinate value adds one.Often move right a pixel, and corresponding horizontal axis coordinate value adds one.Electronic equipment is detecting pending figure
As in foreground target when, the region shared by foreground target can be marked by a rectangle frame, pass through rectangle frame
The coordinates of four vertex correspondences the position of foreground target can be positioned.
Step 306, if target area be less than or equal to area threshold, in pending image in addition to foreground target
Background area is identified, and obtains image classification label.
Specifically, when target area is less than or equal to area threshold, it is believed that the area of foreground target is smaller, can be according to the back of the body
Scene area obtains image classification label.For example, when the target area of foreground target is less than or equal to 1/2 face of pending image
When product, so that it may be identified with the background area in pending image.When target area is less than or equal to area threshold, may be used also
It, can be with if clear background degree is less than or equal to the first clarity threshold further to obtain the clear background degree of background area
By the way that foreground target is identified, image classification label is obtained；It, can be with if clear background degree is more than the first clarity threshold
By obtaining image classification label to the identification of background area.In this way in shooting image, if if background is blurred, identification is accurate
True rate is not just high, so that it may to generate image classification label by foreground target.
Step 308, if target area is more than area threshold, foreground target is identified, image classification label is obtained.
When target area is more than area threshold, the accuracy rate that foreground target is identified is higher, and foreground target accounts for
It is more accurate to carry out image classification according to foreground target for most of area in pending image.Usually, electronic equipment meeting
Pre-set the classification type of foreground target, then by preset sorting algorithm recognition detection to foreground target particularly belong to
Which preset classification type.For example, electronic equipment can by foreground object classification people, doggie, kitten, cuisines, other etc.
Type, then can recognition detection to foreground target particularly belong to the above-mentioned type which kind of.In the application can with but not
Be limited to by RCNN (Regions with CNN Features), SSD (Single Shot MultiBox Detector),
YOLO (You Only Look Once) scheduling algorithm detects and identifies foreground target.
In one embodiment, the foreground target for including in pending image can be one or more.When pending figure
The foreground target for including as in can choose a foreground target there are when two or more from the foreground target for being included
It is identified, all foreground targets can also be identified.It, can be from pending when a foreground target is identified
A foreground target to be identified is chosen in foreground target included in image, it then can be according to the knowledge to foreground target to be identified
Other result generates image classification label.For example the maximum foreground target of area can be chosen as foreground target to be identified.
If multiple foreground targets are identified, then each foreground target can identify to obtain a foreground type.
It specifically, can be direct if judging to include only a kind of target of foreground type in pending image according to foreground classification result
Image classification label is generated according to the foreground type；If according to foreground classification result judge in pending image only comprising two kinds or
The foreground target of two or more foreground types can then calculate the gross area of the corresponding foreground target of each foreground type, root
Image classification label is generated according to the corresponding maximum foreground type of the gross area.For example, only comprising foreground type being " people " in image
Foreground target, then it is " Pic- people " that directly can generate image classification label according to foreground type " people ".If in image including mesh
A, target B and target C are marked, corresponding foreground type is respectively " people ", " cat " and " people ", then it is corresponding can to calculate separately " people "
The gross area S that target A and target C are accounted in the picture1, gross area S that " cat " corresponding target " B " accounts in the picture2.If S1>
S2, then image classification label will be generated according to foreground type " people "；If S1<S2, then image point will be generated according to foreground type " cat "
Class label.
In one embodiment, it after electronic equipment detects the foreground target in pending image, can calculate each
The corresponding target sharpness of foreground target.Target sharpness can react the clear journey of the textures such as the edge details of foreground target
Degree can reflect the importance of each foreground object, therefore can be carried out according to target sharpness to obtain to a certain extent
The foreground target of identification.For example, user shooting when, can by focal point on the object for comparing concern, and by other
Object carries out Fuzzy processing.When foreground target is identified, can only to the higher foreground target of clarity into
Row identification, the lower foreground target of clarity do not do recognition processing.
It may include several pixels in foreground target, then can be calculated by the gray scale difference of each pixel
Obtain the clarity of foreground target.General clarity is higher, and the gray scale difference between pixel is bigger；Clarity is lower, pixel
Between gray scale difference it is smaller.In one embodiment, can be specifically according to Brenner gradient method, Tenegrad gradient method,
The target sharpness that Laplace gradient method, variance method, energy gradient method scheduling algorithm calculate, but not limited to this.
Specifically, the foreground target that the second clarity threshold is more than to target sharpness is identified, and obtains image classification
Label.First clarity threshold and the second clarity threshold can be identical, can also be different, and not do restriction herein
One clarity threshold and the second clarity threshold can be preset changeless values, can also be dynamic change
Value, does not limit herein.Can also be that user is defeated for example, it may be prestoring a fixed value in the electronic device
Enter, carries out the value of dynamic regulation as needed, can also be the value that each target sharpness according to acquisition is calculated.
