Of course, in the image matching process, the value sequence of k may be gradually increased or decreased, or may be any other value sequence, where the value sequence of k, that is, the number of the image block information for image matching in the first image information, is not limited.
In another embodiment, the image matching using the ith image block information in the first image information and the jth image block information in the second image information includes:
sequentially utilizing the 1 st to M th image block information in the first image information and the M-n image block information in the second image information to carry out image matching;

In an example, as shown in fig. 1b, it is assumed that the first image information is divided into four image block information by a quartering division manner, and the image block information is respectively identified by serial numbers a1, a2, A3 and a 4; similarly, the second image information is divided into four pieces of tile information by quartering, and the pieces of tile information are identified by reference numerals B1, B2, B3, and B4, respectively. Before performing stitching, image matching may be performed using tile information with sequence number a4 in the first image information and tile information with sequence numbers B1-B4 in the second image information in sequence. If matching with the tile information with the serial number B1 is successful, a stitching process may be performed based on the tile information with the serial number a4 in the first image information and the tile information with the serial number B1 in the second image information, so as to achieve stitching of the first image information and the second image information.
According to the image processing method, the first image information and the second image information are acquired, and the second image information is partially overlapped with the first image information; respectively carrying out segmentation processing on the first image information and the second image information to obtain M pieces of image block information, wherein M is a positive integer greater than 1; performing image matching by using the ith image block information in the first image information and the jth image block information in the second image information; and if the matching is successful, executing splicing processing on the first image information and the second image information based on the ith image block information in the first image information and the jth image block information in the second image information. Therefore, splicing processing of front and back two-screen images can be effectively achieved, and the user experience of the long screen capture function is improved.
Example two
Fig. 2a is a schematic flowchart of a second image processing method according to an embodiment of the present invention, where the image processing method in this example is applied to an electronic device, and as shown in fig. 2a, the image processing method includes the following steps:
wherein the second image information is partially overlapped with the first image information.
Specifically, when the long screen capture function is realized, the electronic equipment captures first image information after executing a first screen capture operation triggered by a user; and then, after the user changes the image information in the screen in a mode of pulling down the scroll bar and the like, triggering the second screen capture operation again so that the electronic equipment executes the second screen capture operation and captures the second image information.
here, in order to perform subsequent image matching and splicing operations, the electronic device needs to perform segmentation processing on the first image information and the second image information according to a preset segmentation mode, for example, the first image information and the second image information are divided into four parts, and a value of M is obtained as 4, that is, four pieces of image block information are obtained respectively.
specifically, in the process of performing image stitching, if floating image information exists in a scroll area of a screen, such as a fixed floating icon, the electronic device may first detect the collected first image information and/or second image information to determine whether floating image information exists in the first image information and/or the second image information.
specifically, the electronic device may preferentially perform image matching using the mth image block information in the first image information and the 1 st image block information in the second image information. The mth image block information in the first image information is the image block information at the bottom of the first image information, and the 1 st image block information in the second image information is the image block information at the top of the second image information.
In one example, as shown in fig. 2b, it is assumed that the first image information is divided into four image block information by dividing into four equal parts, which are respectively identified by the numbers a1, a2, A3 and a 4; similarly, the second image information is divided into four pieces of tile information by quartering, and the pieces of tile information are identified by reference numerals B1, B2, B3, and B4, respectively. Before stitching is performed, when floating image information detection is performed on the first image information and the second image information, and floating image information is determined to be absent in the first image information and the second image information, image matching can be preferentially performed by using image block information with a serial number of A4 in the first image information and image block information with a serial number of B1 in the second image information. If the image matching is successful, a splicing process may be performed based on the image block information with the sequence number of a4 in the first image information and the image block information with the sequence number of B1 in the second image information, so as to splice the first image information and the second image information.
According to the image processing method, the first image information and the second image information are acquired, and the second image information is partially overlapped with the first image information; respectively carrying out segmentation processing on the first image information and the second image information to obtain M pieces of image block information; detecting whether floating image information exists in the first image information and/or the second image information; if the floating image information does not exist, carrying out image matching by using the Mth image block information in the first image information and the 1 st image block information in the second image information; and if the matching is successful, executing splicing processing on the first image information and the second image information based on the ith image block information in the first image information and the jth image block information in the second image information. Therefore, splicing processing of front and back two-screen images can be effectively achieved, and the user experience of the long screen capture function is improved.
EXAMPLE III
Fig. 3a is a schematic flowchart of a third image processing method according to an embodiment of the present invention, where the image processing method in this example is applied to an electronic device, and as shown in fig. 3a, the image processing method includes the following steps:
wherein the second image information is partially overlapped with the first image information.
Specifically, when the long screen capture function is realized, the electronic equipment captures first image information after executing a first screen capture operation triggered by a user; and then, after the user changes the image information in the screen in a mode of pulling down the scroll bar and the like, triggering the second screen capture operation again so that the electronic equipment executes the second screen capture operation and captures the second image information.
here, in order to perform subsequent image matching and splicing operations, the electronic device needs to perform segmentation processing on the first image information and the second image information according to a preset segmentation mode, for example, the first image information and the second image information are divided into four parts, and a value of M is obtained as 4, that is, four pieces of image block information are obtained respectively.
specifically, when image stitching is implemented, if floating image information exists in a scroll area of a screen, as shown in fig. 3b, a fixed floating icon "back to top" arrow exists at the bottom of each of first image information (last screen capture) and second image information (next screen capture), the electronic device may first detect the collected first image information and/or second image information to determine whether floating image information exists in the first image information and/or the second image information.
In one example, as shown in fig. 3c, it is assumed that the first image information is divided into four image block information by dividing into four equal parts, which are respectively identified by the numbers a1, a2, A3 and a 4; similarly, the second image information is divided into four pieces of tile information by quartering, and the pieces of tile information are identified by reference numerals B1, B2, B3, and B4, respectively. Before stitching is performed, floating image information detection is performed on the first image information and the second image information, and the floating image information exists in image block information with the sequence number of A4 in the first image information and in image block information with the sequence number of B4 in the second image information; at this time, the image block information with the serial number a3, which does not include the floating image information, may be screened from the first image information, and/or the image block information with the serial number B1, which does not include the floating image information, may be screened from the second image information for image matching. If the image matching is successful, a splicing process may be performed based on the image block information with the sequence number of a3 in the first image information and the image block information with the sequence number of B1 in the second image information, so as to splice the first image information and the second image information.
According to the image processing method provided by the embodiment of the invention, on the basis of respectively carrying out segmentation processing on the first image information and the second image information to obtain M pieces of image block information, whether floating image information exists in the first image information and/or the second image information is detected; if the floating image information exists, determining the position of the image block in the first image information and/or the image information where the floating image information is located; screening ith image block information which does not comprise the floating image information from the first image information based on the image block positions, and/or screening jth image block information which does not comprise the floating image information from the second image information; carrying out image matching by utilizing the ith image block information and the jth image block information; and if the matching is successful, executing splicing processing on the first image information and the second image information based on the ith image block information in the first image information and the jth image block information in the second image information. Therefore, floating image information exists in the rolling area of the screen, and if fixed floating icons and the like exist, the splicing processing of front and back two-screen images is effectively realized by avoiding the mode of image block information containing the floating image information during image matching, and the experience of a user on the long screen capture function is further improved.
Example four
Fig. 4a is a schematic flow chart of a four-image processing method according to an embodiment of the present invention, where the image processing method in this example is applied to an electronic device, and as shown in fig. 4a, the image processing method includes the following steps:

here, in order to perform subsequent image matching and splicing operations, the electronic device needs to perform segmentation processing on the first image information and the second image information according to a preset segmentation mode, for example, the first image information and the second image information are divided into four parts, and a value of M is obtained as 4, that is, four pieces of image block information are obtained respectively.
specifically, when image stitching is implemented, if floating image information exists in a scroll area of a screen, as shown in fig. 3b, a fixed floating icon "back to top" arrow exists at the bottom of each of first image information (last screen capture) and second image information (next screen capture), the electronic device may first detect the collected first image information and/or second image information to determine whether floating image information exists in the first image information and/or the second image information.
step 406, if the image block is located on a dividing line of the image block information in the first image information and/or the second image information, adjusting the dividing line based on the position of the image block to obtain adjusted first image information and/or second image information;
specifically, the electronic device moves the dividing line up or down based on the position of the image block, so that the dividing line avoids the floating image information, and at least one of the M pieces of image block information in the adjusted first image information or second image information does not include the floating image information.
and step 408, if the matching is successful, executing stitching processing on the first image information and the second image information based on the ith image block information in the adjusted first image information and the jth image block information in the second image information.
In one example, as shown in fig. 4b, it is assumed that the first image information is divided into four image block information by dividing into four equal parts, which are respectively identified by the numbers a1, a2, A3 and a 4; similarly, the second image information is divided into four pieces of tile information by quartering, and the pieces of tile information are identified by reference numerals B1, B2, B3, and B4, respectively. Before stitching is performed, floating image information detection is performed on the first image information and the second image information, and floating image information is determined to exist on the dividing lines of the image block information with the sequence numbers of A3 and A4 in the first image information, the dividing lines can be moved downwards, so that at least image block information with the sequence number of A4, which does not include the floating image information, exists in the four image block information in the adjusted first image information; and then, image matching is performed by using the image block information of the A4 and any image block information, such as the image block information with the serial number of B1, of the second image information, wherein the image block information does not include the floating image information. If the image matching is successful, a splicing process may be performed based on the image block information with the sequence number of a4 in the first image information and the image block information with the sequence number of B1 in the second image information, so as to splice the first image information and the second image information.
In another example, as shown in fig. 4c, it is assumed that the first image information is divided into four tile information by a quartering division, which are respectively identified by sequence numbers a1, a2, A3, and a 4; similarly, the second image information is divided into four pieces of tile information by quartering, and the pieces of tile information are identified by reference numerals B1, B2, B3, and B4, respectively. Before stitching is performed, floating image information detection is performed on the first image information and the second image information, and floating image information is determined to exist on the dividing lines of the image block information with the sequence numbers of A1 and A2 in the first image information, the dividing lines can be moved upwards, so that at least image block information with the sequence number of A1, which does not include the floating image information, exists in the four image block information in the adjusted first image information; and then, image matching is performed by using the image block information of the A1 and any image block information, such as the image block information with the serial number of B1, of the second image information, wherein the image block information does not include the floating image information. If the image matching is successful, a splicing process may be performed based on the image block information with the sequence number of a1 in the first image information and the image block information with the sequence number of B1 in the second image information, so as to splice the first image information and the second image information.
