Hereinafter, the method that will elaborate in conjunction with specific embodiments a kind of image procossing provided by the embodiments of the present application, the executing subject of this method is terminal, as shown in Fig. 2, this method comprises:
201, main body object and the background in image to be processed are determined.
Wherein, the image that image to be processed can acquire in real time for the dual camera of terminal, or still image.
In one possible implementation, image to be processed can be divided into the region of preset quantity by terminal, then the color in each region is detected, determine the corresponding region quantity of each color, the corresponding region of the most color of region quantity is determined as background, the more corresponding region of color of region quantity time is true
It is set to main body object, or can also be by object based on the determination of the region in image to be processed in addition to background.
Such as, as shown in Figure 3a, assuming that image to be processed is to stand a people on grassland, then terminal can detecte out the green that most of region in image to be processed is grassland, and then it can determine that the region of image Green to be processed is background, object based on region in addition to green area, as shown in Figure 3b, it is green that terminal, which can detecte out the black region shown in Fig. 3 b by green detector, and the area in the region accounts for the significant proportion of entire picture area, it can be determined that black region shown in Fig. 3 b is background, object based on part in addition to black region.
In alternatively possible implementation, terminal can also determine the main body object and background of image to be processed by the straight line in detection image to be processed, specifically, image to be processed can be divided at least two regions by the straight line detected by terminal, the any region marked off is determined as to the main body object of image to be processed, the region in image to be processed in addition to main body object is determined as background.It should be noted that when using the method for this determining main body object and background, terminal can object executes subsequent step based on each region respectively, object reference composition when determined based on each region respectively.
Such as, as shown in fig. 4 a, it include sandy beach in image to be processed, sea and sky, boundary line between sandy beach and sea is straight line, boundary line between sea and sky is also straight line, as shown in Figure 4 b, image to be processed can be divided into three regions by this two straight lines, then terminal can be by main body based on the determination of any one region, in addition two regions are background, or, terminal can also be respectively by region 1, object based on region 2 and the determination of region 3, and by executing the determining object reference composition based on region 1 when object of subsequent step, object reference composition based on region 2 when object, and the object reference composition based on region 3 when object.
Wherein, a variety of composition detectors can be configured in terminal, terminal can detect image to be processed with each composition detector respectively, more accurately to determine main body object and background, such as determine that the background of image to be processed is not solid color by first composition detector, or the region in image to be processed in addition to background is not concentrated, i.e., there may be multiple main body objects in image to be processed, then terminal can determine that image to be processed and first composition detector mismatch.It can then continue to detect image to be processed using second composition detector, assuming that second composition detector is linear detector, the straight line in image is detected by the linear detector, main body object and the background in image to be processed can be then determined according to the testing result of linear detector, if straight line is still not detected in linear detector, can continue to be detected with other composition detectors.
In addition, terminal can also identify object included in image to be processed by depth learning technology, to more intelligently determine main body object and background.

202, according to the main body object and background in image to be processed, the corresponding object reference composition of image to be processed is determined.
Wherein, it has been stored in advance various with reference to composition in terminal, terminal can match the feature of the main body object in image to be processed and background with pre-stored with reference to composition, and then the selection object reference composition from pre-stored reference picture.
It should be noted that embodiments herein does not limit the quantity of object reference composition, when image to be processed matches with multiple pre-stored reference compositions, then this step can determine multiple object reference compositions.
203, image to be processed and object reference composition are calibrated, obtain target image by the position according to the size of main body object and main body object in image to be processed.
It is understood that after image to be processed and object reference composition are calibrated, the target image of the available mode of composition for meeting object reference composition.
It should be noted that needing respectively to calibrate image to be processed with each object reference composition in this step, respectively obtaining the target image for meeting each object reference composition if defining multiple object reference compositions in step 202.
After determining multiple target images, a target image can be selected as final target image by user, or a target image can also be randomly choosed by terminal as final target image, if the randomly selected target image of terminal does not meet user's requirement, user can also choose other target images manually.
Illustratively, as shown in Figure 5, assuming that defining three object reference compositions in step 202, three target images are determined according to these three object reference compositions, respectively target image 1, target image 2 and target image 3, terminal can receive the selection instruction of user's input, the target image for being selected user according to selection instruction is as final target image, such as, in Fig. 5, assuming that user has carried out clicking operation to target image 2, then terminal is by target image 2 as final target image.
The method for the image procossing that embodiments herein provides, the photo picture sense difference shot is caused to be compared since user lacks composition experience in compared with the prior art, terminal can be according to the main body object and background in image to be processed in the application, determine the corresponding object reference composition of image to be processed, there is composition experience without photographer, terminal can automatically calibrate image to be processed and object reference composition, obtain the target image for meeting object reference composition, by being calibrated with object reference composition, improve the aesthetic measure of target image, so that the picture sense for the photo that terminal is shot is more preferable.
In a kind of possible implementation that embodiments herein provides, as shown in Figure 6, above-mentioned steps 203, the position according to the size and main body object of main body object in image to be processed, image to be processed and object reference composition are calibrated, target image is obtained, specifically may be implemented are as follows:
2031, calibration parameter is determined according to object reference composition.
Wherein, the position of the standard proportional and main body object of entire picture in entire picture should be accounted for by main body object being included at least in calibration parameter.
2032, calibration operation is carried out to image to be processed according to calibration parameter, obtains the target image for meeting calibration parameter.
It wherein, can be the operations such as cutting, rotation to the calibration operation of image to be processed.
It is understood that obtained target image will meet object reference composition after picture to be processed is calibrated according to calibration parameter.As an example, if using Fig. 3 as image to be processed, root
Determine that an object reference is patterned into trichotomy composition according to Fig. 3, trichotomy composition, which refers to, is divided into three equal parts with two horizontal lines on longitudinal direction for scene, it is divided into three equal parts with two vertical lines in the transverse direction, it is equivalent to two horizontal lines of a scene and two vertical line segmentations, similar to " well " word, four crosspoints can be thus obtained, and then are located in one of main body object on crosspoint.Image to be processed shown in Fig. 3 does not meet trichotomy composition, so terminal can calculate calibration parameter, image to be processed is cut by calibration parameter to obtain the target image for meeting trichotomy composition, as shown in Figure 7, after cutting according to the thick line in Fig. 7 to image to be processed, the target image for meeting trichotomy composition can be obtained.It should be noted that, if image to be processed is the dynamic image that camera is being shot, then terminal can show trichotomy composition on shooting interface, as shown in Figure 8, the position of object based on four crosspoints in Fig. 8, by show trichotomy composition can prompt user to camera current shooting to image to be processed be adjusted, it is overlapped the main body object that actually photographed and the position of the main body object indicated in trichotomy composition, to shoot the target image for meeting trichotomy composition.Assuming that another object reference composition that image to be processed according to Fig.3, is determined is center composition, it then can be using center composition as the option of an object reference composition, if user has selected trichotomy composition, trichotomy composition is then shown in the shooting interface of terminal, if user has selected center composition, the shooting interface display of terminal is center composition.
