Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for generating a certificate photo in some embodiments of the present application. The certificate photo generation method comprises the following steps:
s101, acquiring a non-standard certificate photo image of a target user acquired by a camera, and identifying a first part which does not accord with a standard in the non-standard certificate photo image;
s102, acquiring a plurality of reference images uploaded by the target user;
s103, matching the multiple reference images with the non-standard identification photo images respectively to obtain at least one target reference image;
and S104, processing each first part of the non-standard identification photo image according to the at least one target reference image to obtain a standard identification photo image.
In step S101, one or more first portions in the non-standard identification photo image do not meet the standard of the standard identification photo, and therefore, the one or more first portions need to be processed. The non-standard certificate photo image is obtained by acquiring an image of a user by a camera of the certificate photo shooting equipment. Wherein the first part may be that the eyes are not qualified due to the beauty pupil, the hairstyle of the hair is not qualified due to the long hair, or the corresponding first part is not qualified due to the lip nails, the nose rings, etc.
In step S102, the reference images are photos of the user uploaded by the user, and the first portion of the non-standard identification photo image is repaired or processed by selecting an appropriate reference image from the photos as a target reference image.
In step S103, the target reference image is mainly used for the computer to select a post-repair area for repairing or processing the first portion of the non-standard identification photo image. The resolution and the definition of the target reference image are more than or equal to those of the non-standard identification photo image, so that the problem that the identification rate of the non-standard identification photo image is low is solved. Of course, at least a region corresponding to one first region must be present as the target reference image and can be used as a post-compensation region corresponding to the first region, so that the corresponding first region can be subjected to image processing by using the post-compensation region. Therefore, it must be satisfied that the degree of matching with the non-standard identification photograph image is greater than a preset threshold value, which may be 95%, when selecting the target reference image, although it is not limited thereto.
In step S104, after the post-compensation region in each extracted target reference image is appropriately cut, rotated, and color-matched by a common image synthesis method or an image fusion method, the region corresponding to the first portion of the non-standard identification photo image is subjected to image fusion or simple overlay, so that each first portion of the non-standard identification photo image is modified or processed to meet the standard of the identification photo.
In some embodiments, as shown in fig. 2, this step S103 may comprise the following sub-steps: s1031, respectively matching each reference image with the non-standard certificate photo, and taking the reference image as an alternative image if the matching degree of the reference image and the non-standard certificate photo is greater than a preset threshold value; s1032, judging whether the area corresponding to the first part in the alternative image meets the standard of a standard certificate photo or not; and S1033, if the candidate images are consistent with the target reference image, taking the candidate images as the target reference image to obtain at least one target reference image.
The identification photo standard is preset, an area corresponding to each first part is extracted from the alternative image, then the image characteristics of the area are compared with the standard required to be met by the area, and if the standard is met, the alternative image is judged to be a target reference image of the corresponding first part. When comparing the image characteristics of the area with the criteria that the area needs to meet, the method in the prior art or the neural network may be used for the determination.
In some embodiments, this step S103 may further include the following sub-steps: s1034a, if there are a plurality of target reference images corresponding to the same first location, selecting the target reference image with the highest matching degree with the non-standard identification photo image as the final target reference image corresponding to the first location. The final target reference image is an image used for processing the corresponding first portion.
Alternatively, in some embodiments, the step S103 may further include the following sub-steps: s1034b, selecting a first target reference image to be used finally from the at least one target reference image, where the number of post-supplement regions corresponding to the first location in the first target reference image and meeting the certification standards is the largest; selecting at least one second target reference image from the remaining at least one target reference image; the second target reference image is used for supplementing a complementary region corresponding to the first part, which is lacked by the first target reference image.
For example, if there are a total of 5 first locations in the non-standard identification photograph image: a1, A2, A3, A4 and A5. And the selected target reference images are B1, B2, B3 and B4. Among them, B1 includes posterous regions a1, a2, A3, and a4, B2 includes posterous regions a2, B3 includes posterous regions a5, and B4 includes posterous regions a 5. And the degree of matching of the B3 with the non-standard identification photo image is greater than the degree of matching of the B4 with the non-standard identification photo image. Therefore, B1 is selected as the first target reference picture and B3 is selected as the second target reference picture.
In some embodiments, this step S104 may include the following sub-steps: and processing the corresponding first part of the non-standard identification photo image according to the first target reference image and the second target reference image to obtain a standard identification photo image. The scenes are continuously adopted, namely, the A1, A2, A3 and A4 of the non-standard identification photo image are processed by adopting the first target reference image, and the A5 of the non-standard identification photo image is processed by adopting the second target reference image.
In some embodiments, as shown in fig. 3, the step S104 may further include the following sub-steps before processing the corresponding first portion of the non-standard identification photo image: s1041, acquiring first age information of the non-standard identification photo image; s1042, acquiring second age information of the first target reference image and the second target reference image; s1043, processing the first target reference image and the second target reference image according to the second age information and the first age information, so that the corresponding ages of the first target reference image and the second target reference image are matched with the age of the non-standard identification photo image.
The first age information and the second age information may be input by a user or acquired from image generation information. Therefore, in order to improve the recognition degree of the standard certificate image, the corresponding postcompensation regions of each of the first target reference image and the second target reference image need to be processed to match the age of the current year, and then the first target reference image and the second target reference image which are age-matched are used for processing the corresponding first part of the non-standard certificate image by the non-standard certificate image to obtain the standard certificate image, which is beneficial to improving the expression capability of the obtained standard certificate image to users. Processing photos based on age is prior art and therefore need not be described in further detail.
In some embodiments, the step S104 may further include the following sub-steps before processing the corresponding first portion of the non-standard identification photo image: s104a, acquiring first physiological characteristic information of the non-standard certificate photo image; s104b, acquiring second physiological characteristic information of the first target reference image and the second target reference image; s104c, processing the first target reference image and the second target reference image according to the second physiological characteristic information and the first physiological characteristic information, so that the physiological characteristics corresponding to the first target reference image and the second target reference image are matched with the physiological characteristics of the non-standard identification photo image; the physiological characteristic information includes skin color, wrinkle information, hair color information, and facial muscle contour information. For example, the skin color of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the skin color of the corresponding region of the current non-standard certificate photo image, the wrinkle or the texture of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the wrinkle or the texture of the corresponding region of the current non-standard certificate photo image, or the muscle thickness or the contour of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the muscle thickness or the contour of the corresponding region of the current non-standard certificate photo image, then the first target reference image and the second target reference image after physiological feature matching are used for processing the corresponding first part of the non-standard certificate photo image by the non-standard certificate photo image to obtain the standard certificate photo image, the method is favorable for improving the performance of the obtained standard certificate photo image to the user.
As can be seen from the above, in the identification photo generation method provided in the embodiment of the present application, the non-standard identification photo image of the target user, which is acquired by the camera, is obtained, and the first portion that does not meet the standard in the non-standard identification photo image is identified; acquiring a plurality of reference images uploaded by the target user; matching the plurality of reference images with the non-standard identification photo images respectively to obtain at least one target reference image; processing each first part of the non-standard identification photo image according to the at least one target reference image to obtain a standard identification photo image; therefore, the convenience of taking the standard certificate photo by the user is improved, dressing and dressing processing according with the standard certificate photo is not required to be specially carried out, and the user experience can be improved.
As shown in fig. 4, an embodiment of the present application further provides a system for generating a certificate photo, where the system includes: a memory 201 and a processor 202, wherein the memory 201 includes a program of a certificate photo generation method, and the program of the certificate photo generation method realizes the following steps when executed by the processor 202: acquiring a non-standard certificate photo image of a target user acquired by a camera, and identifying a first part which does not accord with a standard in the non-standard certificate photo image; acquiring a plurality of reference images uploaded by the target user; matching the plurality of reference images with the non-standard identification photo images respectively to obtain at least one target reference image; and processing each first part of the non-standard identification photo image according to the at least one target reference image to obtain a standard identification photo image.
Wherein, one or more first parts in the non-standard certificate photo image do not accord with the standard of the standard certificate photo, therefore, the one or more first parts need to be processed. The non-standard certificate photo image is obtained by acquiring an image of a user by a camera of the certificate photo shooting equipment. Wherein the first part may be that the eyes are not qualified due to the beauty pupil, the hairstyle of the hair is not qualified due to the long hair, or the corresponding first part is not qualified due to the lip nails, the nose rings, etc.
The plurality of reference images are photos of the user uploaded by the user, and a proper reference image is selected from the photos to be used as a target reference image to repair or process the first part of the non-standard certificate photo image.
The target reference image is mainly used for a computer to select a post-repair area so as to repair or process the first part of the non-standard certificate photo image. The resolution and the definition of the target reference image are more than or equal to those of the non-standard identification photo image, so that the problem that the identification rate of the non-standard identification photo image is low is solved. Of course, at least a region corresponding to one first region must be present as the target reference image and can be used as a post-compensation region corresponding to the first region, so that the corresponding first region can be subjected to image processing by using the post-compensation region. Therefore, it must be satisfied that the degree of matching with the non-standard identification photograph image is greater than a preset threshold value, which may be 95%, when selecting the target reference image, although it is not limited thereto.
After the post-compensation area in each extracted target reference image is subjected to appropriate clipping, rotation, color mixing and other processing by a common image synthesis method or an image fusion method, the area corresponding to the first part of the non-standard certificate photo image is subjected to image fusion or simple coverage, and therefore each first part of the non-standard certificate photo image is modified or processed to be in accordance with the standard of the certificate photo.
In some embodiments, the program of the certificate photo generation method, when executed by the processor, implements the steps of: matching each reference image with the non-standard certificate photo respectively, and taking the reference image as an alternative image if the matching degree of the reference image and the non-standard certificate photo is greater than a preset threshold value; judging whether the area corresponding to the first part in the alternative image meets the standard of a standard certificate photo or not; and if so, taking the alternative image as a target reference image to obtain at least one target reference image.
The identification photo standard is preset, an area corresponding to each first part is extracted from the alternative image, then the image characteristics of the area are compared with the standard required to be met by the area, and if the standard is met, the alternative image is judged to be a target reference image of the corresponding first part. When comparing the image characteristics of the area with the criteria that the area needs to meet, the method in the prior art or the neural network may be used for the determination.
In some embodiments, the program of the certificate photo generation method, when executed by the processor, implements the steps of: and if the number of the target reference images of the same first part is multiple, selecting the target reference image with the highest matching degree with the non-standard identification photo image as a final target reference image corresponding to the first part. The final target reference image is an image used for processing the corresponding first portion.
Alternatively, in some embodiments, the program of the certificate photo generation method realizes the following steps when executed by the processor: selecting a first target reference image to be used finally from the at least one target reference image, wherein the number of post-supplement areas corresponding to the first part and meeting the certificate photo standard in the first target reference image is the largest; selecting at least one second target reference image from the remaining at least one target reference image, the second target reference image being used to supplement a complementary region corresponding to the first location that is missing from the first target reference image.
For example, if there are a total of 5 first locations in the non-standard identification photograph image: a1, A2, A3, A4 and A5. And the selected target reference images are B1, B2, B3 and B4. Among them, B1 includes posterous regions a1, a2, A3, and a4, B2 includes posterous regions a2, B3 includes posterous regions a5, and B4 includes posterous regions a 5. And the degree of matching of the B3 with the non-standard identification photo image is greater than the degree of matching of the B4 with the non-standard identification photo image. Therefore, B1 is selected as the first target reference picture and B3 is selected as the second target reference picture.
In some embodiments, the program of the certificate photo generation method, when executed by the processor, implements the steps of: and processing the corresponding first part of the non-standard identification photo image according to the first target reference image and the second target reference image to obtain a standard identification photo image. The scenes are continuously adopted, namely, the A1, A2, A3 and A4 of the non-standard identification photo image are processed by adopting the first target reference image, and the A5 of the non-standard identification photo image is processed by adopting the second target reference image.
In some embodiments, the program of the method of generating a certificate photo is executed by the processor to obtain first age information of the non-standard certificate photo image before processing the corresponding first part of the non-standard certificate photo; acquiring second age information of the first target reference image and the second target reference image; and processing the first target reference image and the second target reference image according to the second age information and the first age information, so that the ages corresponding to the first target reference image and the second target reference image are matched with the age of the non-standard certificate photo image.
The first age information and the second age information may be input by a user or acquired from image generation information. Therefore, in order to improve the recognition degree of the standard certificate image, the corresponding postcompensation regions of each of the first target reference image and the second target reference image need to be processed to match the age of the current year, and then the first target reference image and the second target reference image which are age-matched are used for processing the corresponding first part of the non-standard certificate image by the non-standard certificate image to obtain the standard certificate image, which is beneficial to improving the expression capability of the obtained standard certificate image to users. Processing photos based on age is prior art and therefore need not be described in further detail.
In some embodiments, the program of the certificate photo generation method, when executed by the processor, implements the steps of: before processing a corresponding first part of the non-standard certificate photo image, acquiring first physiological characteristic information of the non-standard certificate photo image; acquiring second physiological characteristic information of the first target reference image and the second target reference image; processing the first target reference image and the second target reference image according to the second physiological characteristic information and the first physiological characteristic information, so that the physiological characteristics corresponding to the first target reference image and the second target reference image are matched with the physiological characteristics of the non-standard identification photo image; the physiological characteristic information includes skin color, wrinkle information, hair color information, and facial muscle contour information. For example, the skin color of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the skin color of the corresponding region of the current non-standard certificate photo image, the wrinkle or the texture of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the wrinkle or the texture of the corresponding region of the current non-standard certificate photo image, or the muscle thickness or the contour of the complementary region in the first target reference image and the second target reference image is adjusted to be the same as the muscle thickness or the contour of the corresponding region of the current non-standard certificate photo image, then the first target reference image and the second target reference image after physiological feature matching are used for processing the corresponding first part of the non-standard certificate photo image by the non-standard certificate photo image to obtain the standard certificate photo image, the method is favorable for improving the performance of the obtained standard certificate photo image to the user.
As can be seen from the above, the system for generating a certificate photo provided in the embodiment of the present application acquires a non-standard certificate photo image of a target user collected by a camera, and identifies a first portion that does not meet a standard in the non-standard certificate photo image; acquiring a plurality of reference images uploaded by the target user; matching the plurality of reference images with the non-standard identification photo images respectively to obtain at least one target reference image; processing each first part of the non-standard identification photo image according to the at least one target reference image to obtain a standard identification photo image; therefore, the convenience of taking the standard certificate photo by the user is improved, dressing and dressing processing according with the standard certificate photo is not required to be specially carried out, and the user experience can be improved.
