Fig. 3 is a schematic flow chart of a topic selection method provided in the present application, which may be applied to any one of the terminal devices shown in fig. 1 by way of example and not limitation, and the topic selection method may include:

s301, acquiring a topic image.

Wherein the theme image may include at least one theme.

In order to improve the efficiency of searching the titles by the server and reduce the time for sending the title images to the server by the terminal equipment, the terminal equipment can select the titles in a frame mode in advance, so that the images only including the selected titles are sent to the server, and the phenomenon that the time is too long due to the fact that the images occupying large storage space are sent to the server is avoided.

In a possible implementation manner, the terminal device may capture at least one topic according to a preset capture function to obtain a topic image. For example, after detecting an operation of starting a shooting function triggered by a user, a shooting interface may be displayed, and at least one shot title may be displayed in the shooting interface, and if the shooting operation triggered by the user is detected, an image displayed on the shooting interface may be stored to obtain a title image.

Of course, the theme image may also be acquired in other manners, for example, the theme image may be selected from the storage space of the terminal device according to an operation triggered by the user.

S302, identifying the region of the target topic in at least one topic, and generating a region selection frame.

After the topic image is obtained, the target topic in the topic image can be identified, and an area selection frame is generated according to the area where the target topic is located, so that the frame selection of the target topic can be realized through the area selection frame.

In a possible implementation manner, an area matched with the selection trigger position can be selected according to the title contour and the blank area in the title image and in combination with the selection trigger position of the selection operation triggered by the user in the title image, so that the title in the area is used as a target title, and an area selection frame is generated according to the area where the target title is located.

It should be noted that the selection operation may be a single-click operation, a double-click operation, a sliding operation, or the like, and the selection operation is not limited in this embodiment.

S303, adjusting the region selection frame according to the detected adjustment operation to generate a frame selection region completely covering the target title.

In order to further improve the accuracy of framing the target topic, the adjustment operation triggered by the user can be detected, and the size and/or the position of the area selection frame can be adjusted according to the detected adjustment operation, so that the framed selection area obtained after adjustment can completely cover the target topic, and the situation that part of problems are missed when the target topic comprises a plurality of problems is avoided.

In a possible implementation manner, an adjustment operation triggered by a user may be detected, and if the adjustment operation is detected, an adjustment trigger position triggered by the adjustment operation in the topic image may be obtained, and the size or the position of the area frame may be adjusted according to the position relationship between the adjustment trigger position and the area frame, so as to obtain an adjusted frame selection area.

It should be noted that, similar to the selection operation, the adjustment operation may also be a single-click operation, a double-click operation, a sliding operation, or the like, and the adjustment operation is not limited in this embodiment of the application.

S304, cutting the theme image according to the frame selection area to obtain the cut theme image.

Wherein, the cut theme image is matched with the frame selection area.

After the complete frame selection of the target title is completed, the title image can be cut according to the frame selection area, so that the cut title image can be sent to the server, and the problem of long time consumption caused by sending the title image occupying a large storage space to the server is avoided.

In a possible implementation manner, the boundary of the frame selection region can be obtained, the corresponding position of the boundary in the theme image is determined, and the theme image is cut according to the position corresponding to the boundary to obtain an image only including the target theme, that is, the cut theme image, so that the storage space occupied by the cut theme image is smaller than that of the uncut theme image.

To sum up, the topic selection method provided by the embodiment of the application identifies an area where a target topic is located in at least one topic by obtaining a topic image including at least one topic, generates an area selection frame, adjusts the area selection frame according to a detected adjustment operation, generates a frame selection area completely covering the target topic, and finally cuts the topic image according to the frame selection area to obtain the cut topic image. The method comprises the steps of identifying the area where the target title is located, generating an area selection frame, adjusting the area selection frame according to an adjusting operation, generating a frame selection area completely covering the target title, finally cutting to obtain a cut title image matched with the frame selection area, wherein the storage space occupied by the cut title image is smaller than that of an uncut title image, so that the time spent on sending the cut title image to a server is reduced, and the efficiency of retrieving the target title is improved.

Furthermore, the region where the target topic is located is identified and the region selection frame is generated, so that the situation that a user manually selects the frame is avoided, the time spent on selecting the target topic by the frame is reduced, and the efficiency of selecting the topic by the frame is improved.

Furthermore, the range of the region selection frame is adjusted according to the adjustment operation, so that the user can adjust the range of the region selection frame on the basis of the region selection frame, the target subject can be precisely selected, and the accuracy of selecting the target subject by frames is improved.

Fig. 4 is a schematic flow chart of another topic selection method provided in the present application, which may be applied to any one of the terminal devices shown in fig. 1 by way of example and not limitation, and the topic selection method may include:

s401, acquiring a topic image.

Wherein the theme image may include at least one theme.

S402, carrying out inclination correction on the topic image through a preset correction mode to obtain a corrected topic image.

If the topic image is acquired by shooting, the text in the topic image may be skewed under the influence of the shooting angle, which causes deviation of the area range of the frame selection topic. Therefore, after the topic image is obtained, the tilt correction can be performed on the topic image to obtain a corrected topic image, so that in the subsequent step, the topic can be framed based on the corrected topic image.

In a possible implementation manner, the character outlines of the blank area and the area where the character is located in the title image can be obtained, and then the angles of the blank area and the character outlines are adjusted according to a preset coordinate system, so that the boundaries of the blank area and the boundaries of the character outlines are parallel to a horizontal axis or a vertical axis in the coordinate system, and the corrected title image is obtained.

S403, identifying the region of the target topic in the at least one topic, and generating a region selection frame.

After the topic image is corrected, the target topic in the corrected topic image can be identified, and the region corresponding to the target topic in the corrected topic image is determined by combining the selection operation triggered by the user, so that a region selection frame representing the region where the target topic is located is generated.

In the process of determining the target title, the region box of the region of the target title may be generated in different manners, and S403 may include any one of S403a and S403 b:

s403a, according to the detected selection operation, determining a selection trigger position of the selection operation in the topic image, regarding an area matched with the selection trigger position as an area where the target topic is located from the identified area where at least one topic is located, and then performing frame selection on the area where the target topic is located to generate an area selection frame.

In the process of identifying at least one topic, at least one identification information in the topic image can be identified, the region of each topic in the topic image is determined according to the at least one identification information and the blank region in the topic image, and then the region of the target topic is selected in a frame mode in response to the selection operation to form a region selection frame.

Wherein the identification information is used for indicating the title. For example, the identification information may be a sequence number of the title.

Specifically, each line of characters in the corrected title image may be traversed first, whether identification information exists at the head of each line of characters is determined, if identification information exists in any line, the line of characters may be used as the head line of the title, and an area corresponding to the title to which the line of characters belongs is obtained by combining the blank area adjacent to the lower side of the line of characters.

Therefore, after the identification is performed based on each identification information, the corresponding region of each topic in the corrected topic image can be obtained.

Further, after the region corresponding to each topic is obtained, a selection operation triggered by a user can be detected, and a target topic is selected and framed from at least one topic according to the selection operation. If the selection operation is detected, a selection trigger position for triggering the selection operation in the corrected topic image can be determined, then the selection trigger position is matched with the region where each topic is located, and which region where the topic is located includes the selection trigger position is determined, so that the topic corresponding to the region including the selection trigger position is used as a target topic, and the region where the target topic is located is framed to form a region selection frame.

S403b, according to the detected selection operation, determining a selection trigger position of the selection operation in the theme image, identifying characters around the selection trigger position in the theme image, determining an area where the target theme is located, and performing frame selection on the area where the target theme is located to generate an area selection frame.

After the corrected topic image is obtained, a selection operation triggered by a user can be detected, and according to a position triggering the selection operation, topics near the position are used as target topics, so that an area selection frame corresponding to the target topics is generated.

Specifically, a selection operation triggered by a user may be detected first, and if the selection operation is detected, a selection trigger position for triggering the selection operation in a topic image may be obtained, and identification information, text information, and a blank region around the selection trigger position are identified, so as to obtain a region where a target topic is located, and according to a contour of the region, a region selection frame corresponding to the target topic is generated.

S404, adjusting the area selection frame according to the detected adjustment operation, and generating a frame selection area completely covering the target title.

In order to improve the accuracy of the frame selection of the target topic, the region selection frame can be adjusted again according to the adjustment operation triggered by the user, so that the frame selection region obtained after adjustment can completely cover the target topic, and the accuracy of searching the target topic is improved.

In the process of adjusting the region selection frame, not only the size of the region selection frame can be adjusted, but also the region covered by the region selection frame, that is, the position of the region selection frame, can be adjusted, so as to obtain the frame selection region completely covering the target title.

Optionally, if the adjustment operation is detected, a corresponding adjustment trigger position of the adjustment operation in the topic image may be determined, and then the size and/or the position of the area frame may be adjusted according to a position relationship between the adjustment trigger position and the area frame to obtain the frame selection area.

Specifically, after the area frame is generated, whether the user triggers the adjustment operation may be detected, if the adjustment operation triggered by the user is detected, an adjustment trigger position that triggers the adjustment operation may be determined, and then a position indicated by the adjustment trigger position in the title image is compared with a boundary of the area frame, so as to determine a positional relationship between the adjustment trigger position and the area frame, so that the size and/or the position of the area frame may be adjusted according to the positional relationship, and the frame selected area may be obtained.

Further, in the process of adjusting the size and/or the position of the area frame according to the position relationship, if the adjustment trigger position is located at the boundary of the area frame, the size of the area frame may be adjusted, and/or if the adjustment trigger position is located in the area frame, the position of the area frame may be adjusted.

Specifically, if the boundary of the area frame includes the adjustment position, the size of the area frame may be adjusted according to the sliding direction of the adjustment operation, and if the sliding of the adjustment operation is detected to be completed, the size of the area frame may be stopped from being adjusted, so as to obtain the frame selection area.

Further, if the boundary of the area frame includes the adjustment position, the size of the area frame can be adjusted in different ways according to the position of the adjustment position in the boundary. For example, referring to fig. 5, if the adjustment position is located on any one side of the boundary, the size of the region selection box (indicated by the dashed line box in the figure) may be adjusted in a direction perpendicular to the one side to obtain a box selection region (indicated by the solid line box in the figure); if the adjusting position is located at the included angle of the two edges, the size of the region selection frame can be adjusted along the diagonal direction or the angular bisector direction of the included angle.

However, if the adjustment trigger position is located within the area selection frame, the position of the area selection frame may be adjusted according to the sliding direction of the adjustment operation, so as to obtain the frame selection area.

In addition, if the adjustment trigger position is located outside the region selection frame, it may be determined whether the adjustment trigger position is located in a region corresponding to another topic, if the adjustment trigger position is located in a region corresponding to another topic, the topic in the region where the adjustment trigger position is located may be selected according to the region corresponding to each topic, and if the adjustment trigger position is not located in a region corresponding to another topic, the frame selection region is not adjusted.

S405, cutting the theme image according to the frame selection area to obtain the cut theme image.

Wherein, the cut theme image is matched with the frame selection area.

S406, sending the cut topic image to a server so that the server searches the target topic according to the cut topic image.

After the cut topic image is obtained, the cut topic image can be sent to a server, so that the server searches for a target topic, and a corresponding analysis answer is obtained and fed back to the terminal device. Because the feedback information to the terminal equipment needs to search the terminal equipment which sends the cut topic image, the identification information indicating the terminal equipment can be carried in the process of sending the cut topic image to the server.

In a possible implementation manner, after the cut topic image is obtained, terminal identification information of the terminal device and/or identity identification information of the user account may be obtained, and the cut topic image, the terminal identification information and/or the identity identification information are sent to the server together, so that the server searches according to a target topic in the cut topic image.

The terminal identification information may be an IP (Internet Protocol) address or an MAC (media Access Control) address of the terminal, and the identity identification information may be account information that the user logs in the terminal, for example, the account information may be a mobile phone number of the user or account information of a social network, and the identity identification information is not limited in this embodiment of the present application.

Furthermore, the accuracy of searching for the target topic can be improved, the time spent on searching for the target topic can be reduced, and the efficiency of searching for the target topic can be improved by performing tilt correction on the topic image and performing frame selection and searching on the corrected topic image.

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.
