Each samples pictures and the corresponding classification results of each samples pictures are obtained in advance；Such as samples pictures 1 are grass
Ground scene, samples pictures 2 are snowfield scene, samples pictures 3 are seabeach scene；
Scene classification is carried out to each samples pictures using initial scene classification model, and each according to what is obtained in advance
The classification results of samples pictures calculate the classification accuracy of the initial scene classification model, i.e., whether identify samples pictures 1
For meadow scene, samples pictures 2 be snowfield scene, samples pictures 3 are seabeach scene, samples pictures 4 are lit desert scene；
If above-mentioned classification accuracy is less than preset classification thresholds (such as 75%, that is, the samples pictures identified are less than 3),
The parameter of above-mentioned initial scene classification model is then adjusted, then passes through sample described in parameter scene classification model inspection adjusted
Picture, until the classification accuracy of scene classification model adjusted divides more than or equal to the classification thresholds, and by the scene
Class model is as the scene classification model after training.Wherein, the method for adjusting parameter includes but is not limited to that stochastic gradient descent is calculated
Method, power more new algorithm etc..
Step S103 is handled the picture to be processed according to first testing result and the classification results.
It can specifically include, if first testing result indicates that foreground target, institute are not present in the picture to be processed
The background that classification results instruction identifies the picture to be processed is stated, then：
According to the background classification of the picture to be processed, the picture tupe of the picture to be processed is obtained, and according to
The picture tupe handles the picture to be processed, obtains treated picture；
Alternatively, if first testing result indicates that there are foreground target, the classification results in the picture to be processed
Indicate the background of the unidentified picture to be processed out, then：
It is right according to the classification of each foreground target of first testing result instruction and the position of each foreground target
The picture to be processed is handled；
Alternatively, if first testing result indicates that there are foreground target, the classification results in the picture to be processed
Instruction identifies the background of the picture to be processed, then：
The classification of each foreground target, the position of each foreground target and the institute indicated according to first testing result
The background classification for stating the picture to be processed of classification results instruction, handles the picture to be processed.
Wherein, include but is not limited to foreground target and/or background progress style conversion to the processing of picture to be processed, satisfy
With the adjusting of the image parameters such as degree, brightness and/or contrast.
By the embodiment of the present application, the comprehensive place to foreground target in picture to be processed and background image may be implemented
Reason effectively promotes the treatment effect of picture entirety.
It referring to fig. 2, is the implementation process schematic diagram for the image processing method that the embodiment of the present application two provides, this method can be with
Including：
Step S201 detects the foreground target in picture to be processed, obtains the first testing result, first testing result
It is used to indicate in the picture to be processed with the presence or absence of foreground target, and is used to indicate each prospect when there are foreground target
The position of the classification of target and each foreground target in the picture to be processed；
Step S202 carries out scene classification to the picture to be processed, obtains classification results, the classification results are for referring to
The background for whether identifying the picture to be processed shown, and is used to indicate institute when identifying the background of the picture to be processed
State the background classification of picture to be processed.
Wherein, the specific implementation process of step S201 and S202 can refer to above-mentioned steps S101,102, herein no longer
It repeats.
Step S203 detects the background if classification results instruction identifies the background of the picture to be processed
In target context, obtain the second testing result, second testing result is used to indicate in the background with the presence or absence of background
Target, and the classification for being used to indicate each target context when there are target context and each target context are described to be processed
Position in picture.
As the preferred embodiment of the application, in order to further enhance the treatment effect of picture, the present embodiment is being identified
Out after the background in picture to be processed, it is also necessary to be detected to the target context in the background, in order to subsequent to institute
State the processing of target context.Wherein, the testing result includes but is not limited to：Whether there is or not the instruction of target context letters in the background
Breath, and the classification of each target context and the information of position are used to indicate when comprising target context.Wherein, the background mesh
Mark refers to all kinds of targets, such as blue sky, white clouds, the small grass in greenweed, flower in blue sky etc. of composition background.Further,
In order to more accurately recognize the position of target context, and the target context recognized is distinguished.The present embodiment is being examined
After measuring target context, frame choosing can also be carried out using different selected frame to the target context, for example, dotted line circle select it is white
Cloud, oval circle select flower etc..
Preferably, in order to improve the detection efficiency of target context, the present embodiment can be using the shallow-layer convolution mind after training
