step S101, a camera of the mobile terminal is used for photographing to obtain a first picture, and whether the first picture contains preset information or not is detected.
In this embodiment of the application, the mobile terminal may be a device with an imaging apparatus, such as a camera, a mobile phone, a tablet computer, and the like, a user may use the mobile terminal to take a picture, an original picture generated after taking the picture is referred to as a first picture, and content in the first picture may be detected to determine whether the content of the first picture includes preset information, where the preset information may be information related to user privacy, and includes: the preset text information and the preset image information may be, for example: money, account password, etc., and the image information may be: avatar information, and the like.
Step S102, if the first picture contains the preset information, the first picture containing the preset information is processed to obtain a second picture, and the second picture does not contain the preset information.
In this embodiment of the application, the preset information may be one or more preset information, and the preset information may also only include text information or only include image information, and of course, may also include both text information and image information. If the first picture contains the preset information, the method comprises the following steps: if the first picture contains one or more pieces of preset information. The processing of the first picture containing the preset information can be realized by processing the area of the preset information in the first picture by using a mosaic, namely, the details of the color level of the area where the preset information is located are degraded and the color blocks are disturbed. After the first picture containing the preset information is processed, the obtained picture is called a second picture, and the preset information cannot be identified in the second picture.
As another embodiment of the present application, if the first picture does not include the preset information, the first picture not including the preset information is stored in the first storage space.
In this embodiment of the present application, if the first picture does not include the preset information: after the first picture is matched with the preset information, the first picture cannot be successfully matched with any preset information, namely the first picture does not contain any preset information. The first storage space may be a default space for storing the photo after taking by the system, for example, a default album, or may be a user-defined space for storing the photo after taking, for example, my picture.
And step S103, storing the second picture in a first storage space.
In this embodiment of the application, the first storage space may be an open storage space, the second picture may be a picture that does not include preset information, or may be a picture that does not include privacy information, and the second picture may be stored in the first storage space, or of course, after the user sets a password in the first storage space, the first storage space may also be an encrypted storage space.
According to the embodiment of the application, a first picture is obtained by photographing through a camera of the mobile terminal, whether the first picture contains preset information or not is detected, if the first picture contains the preset information, the first picture containing the preset information is processed to obtain a second picture, the second picture does not contain the preset information and is stored in the first storage space, the preset information can be privacy information of a user, when the picture obtained by photographing through the mobile terminal contains the privacy information, the privacy information in the picture is processed to obtain the picture without the privacy information, and the picture without the privacy information is stored, so that the risk that the privacy information of the user is leaked can be reduced.
Fig. 2 is a schematic flowchart of a photographing processing method according to another embodiment of the present application, where as shown in the drawing, the method may include the following steps:
step S201, a camera of the mobile terminal is used for photographing to obtain a first picture.
Step S202, recognizing the text information in the first picture, and confirming whether the recognized text information contains preset text information.
In this embodiment of the application, an Optical Character Recognition (OCR) technology may be adopted to recognize the text information in the first picture, and after recognizing the text information, the recognized text information and a position of the corresponding text information in the first picture are recorded. The preset text information may be: preset keywords and preset keywords. For example: account number, password, money, etc.
Step S203, matching the first picture with preset image information to determine whether the first picture includes the preset image information.
In an embodiment of the present application, a scene or image information of a first picture may be analyzed by an Artificial Intelligence (AI) technique to determine whether the first picture includes preset image information.
The preset image information can be stored, and then the characteristics of the preset image information are extracted, or the characteristics of the preset image information can be directly stored.
The process of matching the first picture with preset image information to determine whether the first picture contains the preset image information includes:
extracting the characteristics of a first picture, matching the characteristics of the first picture with the characteristics of preset image information, and determining the size of an image block when the first picture is divided into image blocks according to the matching degree of the first picture and the preset image information to be used as the preset size; (the larger the matching degree is, the larger the divided image blocks are, the smaller the matching degree is, the smaller the divided image blocks are, or the larger the matching degree is, the smaller the number of divided image blocks is, the smaller the matching degree is, the larger the number of divided image blocks is);
dividing the first picture into image blocks with preset sizes or image blocks with preset numbers;
extracting the characteristics of each image block, and matching the characteristics of each image block with the characteristics of preset image information;
if the matching degree of the features of the image block and the features of the preset image information is greater than a first threshold and smaller than a second threshold (the preset image information with the matching degree greater than the first threshold and smaller than the second threshold is associated with the first image block to obtain a second image block), splicing the image block with the matching degree greater than the first threshold and smaller than the second threshold and adjacent (such as left adjacent, right adjacent, upper adjacent and lower adjacent) image blocks to obtain a spliced image block;
and continuously matching the characteristics of the spliced image blocks with the characteristics of the associated preset image information until the matching degree of the spliced image blocks and the preset image information is greater than a second threshold value, which indicates that the first picture contains the preset image information, otherwise, the first picture does not contain the preset image information.
By way of example, assume that a first picture is denoted by a, preset image information is denoted by B, a first threshold value is 60%, and a second threshold value is 90%;
matching the first picture a with preset image information B to obtain a matching degree of 60%, and assuming that the number of 60% corresponding image blocks is 9 blocks, dividing the first picture a into 9 image blocks, specifically into three rows and three columns, where the image block may be represented by Aij, the value range of i is 1, 2, and 3, the value range of j is 1, 2, and 3, that is, the 9 image blocks are respectively: a11, a12, a13, a21, a22, a23, a31, a32, a 33;
respectively matching the image blocks Aij with the image B, if the matching degree of the image block A22 and the image B is 65%, and the matching degree of other image blocks except the image block A22 and the image B is less than 60%, splicing the image block A22 and adjacent image blocks (one or more of A12, A21, A32 and A23) to obtain a spliced image block, wherein one or more adjacent image blocks can be preset to be specifically selected, here, taking selecting one adjacent image block as an example, selecting one image block (A12) with the maximum matching degree with the image B from the adjacent image blocks to obtain a spliced image block (A12+ A22);
continuously matching the spliced image blocks with the image B;
if the matching degree is greater than 90%, it may be determined that the first picture includes the preset image information B, and the position of the preset image information B may be obtained according to a process of matching the image block a12+ a22 after the image block splicing with the preset image information B;
if the matching degree is 75%, acquiring adjacent image blocks (A11, A21, A32, A13 and A23) of A12+ A22, continuously acquiring an image block (A11) with the maximum matching degree with the image B from the adjacent image blocks of A12+ A22, and acquiring a spliced image block (A11+ A12+ A22);
continuing to match the spliced image blocks (A11+ A12+ A22) with the image B;
……；
until the matching degree of the spliced image blocks and the image B is greater than 90%, the first picture can be confirmed to contain preset image information B;
if the image blocks after splicing are: a11+ a12+ a13+ a21+ a22+ a23+ a31+ a32+ a33, that is, the stitched image is the first picture, and since the matching degree of the first picture and the image B is 60%, the first picture does not include the preset image information B.
Step S204, if the first picture contains one or more of preset character information and preset image information, generating a detection frame according to the position of the preset character information and/or the position of the preset image information in the first picture.
In this embodiment of the application, if the first picture includes the preset information, the position of the preset information can be correspondingly obtained, the detection frame can be generated according to the position of the preset information, that is, the preset information detected in the first picture, the detection frame can be in a preset shape such as a rectangle, a circle, a triangle, etc., each detected preset information can be correspondingly generated into a detection frame, each preset information is inside the corresponding detection frame, and it can also be understood that the detection frame is the minimum circumscribed rectangle, the circle, the triangle, etc. in the area where the preset information is located.
The detection frame generated according to the position of the preset information can generate a detection frame according to the character information of the adjacent position of the preset information. For example, assuming that the preset information is a "password", after the position of the "password" is confirmed in the first picture, the position of the text information (for example, the right adjacent preset distance) within the adjacent preset distance of the "password" is recorded at the same time, and the detection frame is generated according to the position of the preset information "password" and the position of the text information within the adjacent preset distance. If the preset distance adjacent to the preset information password does not contain the text information, the detection frame can be generated according to the position of the preset information.
Step S205, performing coding processing on the detection frame region, or setting pixel points of the detection frame region to the same gray value, to obtain a second picture.
In the embodiment of the application, the second picture is obtained by performing coding processing on the detection frame region of the first picture, for example, generating a mosaic in the detection frame region; the second picture may also be obtained by setting pixels in the detection frame region of the first picture to the same gray value, for example, setting coordinates of each pixel point in the detection frame region in the RGB color gamut space to the same coordinate value, that is, the detection frame region displays the same color.
Step S206, storing the second picture in a first storage space, and storing the first picture containing the preset information in a second storage space, where the second storage space is an encrypted storage space.
In this embodiment of the application, the second picture does not include the preset information, the second picture is stored in the first storage space, and meanwhile, the original image of the second picture, that is, the first picture including the preset information may be stored in the second storage space, where the second storage space may be an encrypted storage space, or a folder corresponding to the second storage space is set as a hidden folder. The second storage space can be a private storage space set by a user where the mobile terminal is located, even if the stored picture is the first picture containing the preset information, the user does not need to worry about the leakage of the private information, and the risk of the leakage of the private information is reduced.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
