The image processing method provided by the embodiment of the present disclosure may be executed by a terminal device, a server, or other types of electronic devices, where the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. In some possible implementations, the image processing method may be implemented by a processor calling computer readable instructions stored in a memory. Alternatively, the method may be performed by a server. The following describes an image processing method according to an embodiment of the present disclosure, taking an electronic device as an execution subject.

Fig. 1 illustrates a flowchart of an image processing method according to an embodiment of the present disclosure, which includes, as illustrated in fig. 1:

step S11, a target image is acquired, and a contour line of the target area is marked on the target image.

In the embodiment of the disclosure, the electronic device may acquire a target image, and a contour line of a target area may be marked on the target image. The target region may be a region of interest in the target image. For example, in the case that the target image is a pathological image, the target region may be a lesion region in the pathological image, so that the contour line of the lesion region in the pathological image may be adjusted, and the obtained contour line may more accurately mark the lesion region. For another example, in the case where the target image is an image captured for the face of the user, the target region may be a human face region in the image. The contour of the target area may be used to distinguish the target area from other areas in the target image other than the target area, and the contour of the target area is normally closed, and in some cases, the contour of the target area may also be non-closed. The contour line of the target area may be determined according to a user operation, that is, the user may manually outline the contour line of the target area. In some implementations, the contour line of the target region may be obtained by performing target detection on the target image, for example, the target image may be subjected to target detection through some trained neural networks or detection algorithms, a target region in the target image is determined, and the target region is labeled to obtain the contour line of the target region.

Here, the target image may include at least one target region, and each target region may be labeled by a contour line. The contour line of each target area can have a corresponding contour number, and the contour numbers of the contour lines of different target areas are different, so that the contour lines of different target areas can be distinguished through the contour numbers.

Here, the electronic device may obtain the target image in a local storage or cache, or may obtain the target image at another electronic device in a wired manner or a wireless manner.

Step S12 is a step of determining a relative positional relationship between the editing tool acting on the target image and the contour line based on the contour line.

In the embodiment of the present disclosure, a user may edit the contour line of the target region using an editing tool, and the editing tool may be controlled by a mouse, so as to adjust the contour line. When the target image is in the editing mode, the editing tool can act on the target image, and the electronic equipment can determine the relative position relationship between the editing tool acting on the target image and the contour line according to the image position of the editing tool and the image position of the contour line.

Here, the relative positional relationship between the editing tool and the contour line may include at least one of: the editing tool is inside the contour line, the editing tool is outside the contour line, and the editing tool intersects the contour line. The editing tool is located inside the contour line, and the target area indicated by the contour line can be understood to include the image area where the editing tool is located, and the boundary of the editing tool can be circumscribed with the contour line. The editing tool is outside the contour line, it can be understood that the image area where the editing tool is located is outside the target area indicated by the contour line, and the boundary of the editing tool can be inscribed in the contour line. The editing tool intersects with the contour line, which can be understood as that the image area where the editing tool is located intersects with the target area indicated by the contour line, and the boundary of the editing tool and the contour line have a plurality of intersection points.

Here, the editing tool may be a preset shape, or may be determined according to a user selection. The shape of the editing tool can be a regular or irregular shape such as a circle, an ellipse, a quadrangle, a polygon and the like. The shape of the editing tool is related to the shape of the line drawn by the editing tool, for example, where the shape of the editing tool is a circle, the line drawn by the editing tool may be a circle or a portion of a circle.

Here, the size of the editing tool may be adjusted, and in a case where the size adjustment instruction is received, the size of the editing tool may be adjusted in response to the size adjustment instruction, so that the size of the editing tool may be adjusted according to an actual application scene, and the method is suitable for adjusting the irregular-shaped contour line. For example, in the case of editing a contour line by an editing tool, a user may scroll a scroll wheel of a mouse, a user operation of the scroll wheel may trigger a size adjustment instruction, and in the case of receiving the size adjustment instruction, the size of the editing tool may be adjusted according to an adjustment parameter for enlargement or reduction carried by the size adjustment instruction. Therefore, the contour line can be adjusted under various contour modification scales, and a user can add or delete the contour line of the target area conveniently.

And step S13, responding to the editing instruction, and executing and editing operation on the contour line based on the relative position relation to obtain the adjusted contour line.

In the embodiment of the present disclosure, the editing operation corresponding to the relative position relationship may be determined according to the relative position relationship between the editing tool and the contour line, and different relative position relationships may correspond to different editing operations. When an edit instruction is received, in response to the edit instruction, an edit operation corresponding to the relative positional relationship may be performed on the partial contour of the contour line acted on by the editing tool, for example, the partial contour acted on by the editing tool may be extended or shortened, and the contour line after adjustment of the target region may be obtained after the adjustment is completed. The partial contour may be a portion of a contour line. Here, the edit instruction may be triggered based on a user operation, for example, an edit instruction may be triggered by a user operation of clicking a mouse or a user operation of long-pressing a mouse. The present disclosure is not limited to a specific user operation that triggers an edit instruction.

Here, in the case of performing an editing operation on the contour line of the target region, the control points may be automatically added according to the action position of the editing tool on the contour line, and then the added control points and the existing control points on the contour line may be connected to form an adjusted contour line, which passes through the newly added control points and the existing control points on the contour line. In some implementations, under the action of the editing tool, existing control points on the contour line may be deleted while adding new control points, and in this case, the adjusted contour line may be formed according to the new control points and the remaining control points on the contour line. The adjusted contour line passes through the newly added control points and the rest control points on the contour line.

It will be appreciated that control points may be used to control the shape of the contour lines and connecting control points may form the contour lines. In some implementations, when the adjusted contour line is formed according to the control points, smooth interpolation may be performed based on the control points, that is, a smooth curve is drawn between the control points, so that smooth transition between different control points is possible, and a smooth adjusted contour line is obtained. Here, when performing smooth interpolation based on the control points, smooth transition between the control points may be achieved by some interpolation algorithm, for example, by a Bezier interpolation algorithm, a spline interpolation algorithm, or the like.

In some implementations, since the number of control points included in the contour line is continuously changed during the process of editing the contour line, if the number of control points of the contour line is increased too much, the performance of the system may be affected, so that the number of control points included in the contour line may be counted during the process of performing the editing operation on the contour line, and in the case that the number of control points is greater than the preset number threshold, the control points included in the contour line may be resampled, that is, in the case that the shape of the contour line is not changed, the density distribution and the spatial interval of the control points on the contour line are adjusted, so that the control points on the contour line are less than or equal to the preset number threshold. Here, the preset number threshold may be a maximum value of the number of control points that is set according to an actual application scenario or a requirement.

Here, the editing mode of the outline may be exited according to the received stop instruction, for example, the stop instruction may be triggered according to a user operation of a single click or a double click, and in a case where the stop instruction is received, the editing mode of the outline may be exited. In some implementations, the editing mode of the contour line can be automatically exited when the duration of the editing tool without any operation reaches a preset duration.

The image processing scheme provided by the disclosure can automatically adjust the contour line according to the relative position relation between the editing tool and the contour line, so that the shape and/or position of the contour line can be changed, frequent switching between a painting tool and an eraser tool by a user can be reduced, the operation is simple, and the requirement of the user for modifying the contour line can be met.

In some implementations, the object image may be marked with contour lines of a plurality of object regions, and in order to reduce the misoperation of different contour lines, the contour lines of the object regions may be edited while the contour lines of the object regions are in a selected state, so that the selected contour lines may be adjusted, and unselected contour lines are in a non-editable state, thereby reducing the occurrence of the misoperation.

In some implementation manners, the editing operation corresponding to the relative position relationship may also be prompted by the operation identifier, and the operation identifiers corresponding to different editing operations are different. For example, the editing operation may include a first editing operation, a second editing operation, and a third editing operation, where an operation identifier corresponding to the first editing operation may be denoted by "-", an operation identifier corresponding to the second editing operation may be denoted by "+", and an operation identifier corresponding to the third editing operation may be denoted by an operation identifier different from the first editing operation and the second editing operation. Therefore, the editing operation corresponding to the current relative position relation of the user can be prompted through the operation identifier, and the user can change the relative position relation between the editing tool and the contour line of the target area through the prompting of the operation identifier so as to select the editing operation.

In step S13, the outline may be edited based on the relative position relationship to obtain the adjusted object region, and the editing performed on the outline may be described in various ways.

In some implementations, in a case where the editing tool is located outside the contour line, that is, the editing tool is separated from or circumscribed about the contour line, the first editing operation may be performed by the editing tool, and the first editing operation may be an operation of pushing the contour line from the outside of the contour line toward the inside of the contour line, that is, under the action of the first editing operation, a part of the contour line on which the editing tool acts may be changed according to a boundary of the editing tool, so that a shape of the part of the contour line on which the editing tool acts may fit the boundary of the editing tool, and at the same time, the part of the contour may not move to the inside of the editing tool, and an effect of the editing tool pushing the contour line from the outside of the contour line toward the inside of the contour line may be exhibited, and the adjusted contour line of the target. The area of the region corresponding to the contour line after adjustment is smaller than the area of the region corresponding to the contour line before adjustment, and by adopting the mode, the adjustment effect of reducing the contour line can be realized, the adjustment mode is simple, and the flow of contour line adjustment is simplified.

Fig. 2 is a schematic diagram illustrating a first editing operation performed on a contour line according to an embodiment of the present disclosure, where a shows the contour line before contour line adjustment, and in response to an editing instruction triggered by a user operation of pressing a mouse for a long time, an editing tool may move in a direction indicated by a dotted arrow under the action of the first editing operation, so as to push the contour line from outside to inside. B shows the contour line after the contour line adjustment, the editing tool is moved to the position indicated by the dotted arrow, and the adjusted contour line fits the boundary of the editing tool.

In some implementations, in a case where the editing tool is located inside the contour line, that is, the editing tool is internally included or inscribed in the contour line, the second editing operation may be performed by the editing tool, and the second editing operation may be an operation of pushing the contour line from the inside of the contour line toward the outside of the contour line, that is, under the action of the second editing operation, a partial contour applied to the contour line by the editing tool may be changed according to a boundary of the editing tool, so that a shape of the partial contour applied to the contour line by the editing tool fits a boundary of the editing tool, and at the same time, the partial contour does not move to the inside of the editing tool, and an effect that the editing tool pushes the contour line from the inside of the contour line toward the outside of the contour line is presented, and the contour line after the adjustment is completed can be obtained after. The area of the region corresponding to the contour line after adjustment is larger than the area of the region corresponding to the contour line before adjustment, and by adopting the mode, the effect of enlarging the contour line adjustment can be realized, the adjustment mode is simple, and the flow of contour line adjustment is simplified.

Fig. 3 is a schematic diagram illustrating a second editing operation performed on the contour line according to an embodiment of the disclosure, where a shows the contour line before the contour line is adjusted, and in response to an editing instruction triggered by a user operation of pressing a mouse for a long time, the editing tool may move in a direction indicated by a dotted arrow under the action of the second editing operation, and the contour line is pushed from inside to outside. B shows the contour line after the contour line adjustment, the editing tool is moved to the position indicated by the dotted arrow, and the adjusted contour line fits the boundary of the editing tool.

In some implementations, in a case where the editing tool intersects with the target area corresponding to the contour line, that is, in a case where there is an intersection between the image area where the editing tool is located and the target area indicated by the contour line, a third editing operation may be performed by the editing tool, and the third editing operation may be an operation of drawing a newly added contour. Under the action of the third editing operation, a new contour can be formed according to the boundary of the editing tool, the new contour can form a new contour line with the contour of the part of the original contour line which is not intersected with the editing tool, and the contour line of the target area after adjustment can be obtained after the adjustment is finished. In this way, free drawing of the contour line can be achieved.

In the case where the third editing operation is performed by the editing tool, if the center of the editing tool is located inside the contour line, that is, the editing tool intersects the contour line of the target region, and the center of the editing tool is located inside the contour line, the contour line where the contour line intersects the boundary of the editing tool may be replaced with a new contour, and the adjusted contour line of the target region may be obtained after the adjustment is completed. The newly added contour may be formed by a boundary of an editing tool located outside the contour line, and in some examples, the boundary of the editing tool located outside the contour line may be used as the newly added contour, the newly added contour may be added, a part of the contour line where the contour line intersects with the boundary of the editing tool may be deleted, and the contour line after the adjustment of the target region may be obtained after the adjustment is completed, so that the newly added contour may be freely drawn outside the original contour line.

FIG. 4 illustrates a schematic diagram of performing a third editing operation on a contour line according to an embodiment of the present disclosure. Wherein, A shows the contour line before contour line adjustment, under the condition that the center of the editing tool is positioned in the contour line and intersected with the contour line, in response to an editing instruction triggered by a user operation of clicking a mouse by a user, under the action of a third editing operation, the boundary of the editing tool positioned outside the contour line is taken as a new contour, the new contour is added, and the partial contour (dotted line part) intersected with the boundary of the contour line and the editing tool is deleted. And B, showing the contour line after contour line adjustment, and adding a boundary of the contour line fitting editing tool.

In the case where the third editing operation is performed by the editing tool, if the center of the editing tool is located outside the contour line, that is, the editing tool intersects the contour line of the target region, and the center of the editing tool is located outside the contour line, the boundary of the editing tool located inside the contour line may be regarded as the newly added contour. The two image areas formed by the new contour and the contour line are further determined, namely, the new contour in the target area can divide the target area into two image areas. The new contour may be further drawn based on the areas of the two image areas on the basis of the original contour of the target area, and the adjusted contour of the target area may be obtained after the adjustment is completed. By the method, different new contour drawing modes can be provided for the user according to the areas of the two image areas, and different contour adjustment requirements of the user are further met.

Wherein, A shows the contour line before contour line adjustment, under the condition that the center of the editing tool is positioned outside the contour line and intersected with the contour line, in response to an editing instruction triggered by a user operation of clicking a mouse by a user, under the action of a third editing operation, the boundary of the editing tool positioned inside the contour line is taken as a new contour, the new contour is added, and the partial contour (dotted line part) intersected with the boundary of the contour line and the editing tool is deleted. And B, showing the contour line after contour line adjustment, and adding a boundary of the contour line fitting editing tool.

In the above implementation manner, the new contour may be drawn based on the areas of the two image areas on the basis of the contour line to obtain the contour line after the target area is adjusted, and a manner of drawing the new contour based on the areas of the two image areas is exemplified below by some examples.

In one example, a ratio of areas between two image regions may be determined, and then the ratio may be compared with an end point of a preset threshold interval, and in a case where the ratio is within the preset threshold interval, a new contour may be drawn on the basis of an original contour, the new contour may be formed by a boundary of an editing tool located inside the original contour, and the adjusted contour may include contours of the two image regions, for example, a new contour may be copied on the basis of the drawn new contour, one new contour and a part of the contour of the target region form a contour of one image region, and the other new contour and another part of the contour of the target region form a contour of the other image region, so as to obtain contours of the two image regions. In some examples, a new contour number may be automatically generated, the contour number may indicate the contour of one of the two image regions, and the contour of the other of the two image regions may retain the contour number of the original contour of the target region.

Here, the preset threshold interval may be set according to an actual application scenario, for example, may be set to (0.8, 1.25). When the ratio of the two image areas is within the preset threshold interval, the areas of the two image areas are considered to be relatively close, in this case, the user can be considered to split the contour line of the target area into two, the newly added contour can be drawn on the basis of the original contour line of the target area, the newly added contour and the contour line of the target area can form the contour lines of the two image areas, so that the original contour line of the target area can be adjusted into the contour lines of the two image areas, the operation is simple, and the contour adjusting efficiency is improved.

In another example, in a case that the ratio of the areas between the two image regions is not within the preset threshold interval, the area difference between the two image regions may be considered to be large, in this case, a new contour is drawn based on the contour line of the target region, the new contour may be formed by the boundary of an editing tool located inside the original contour line, and a portion of the contour line of the target region corresponding to the first image region is deleted, and the adjusted contour line of the target region may be obtained after the adjustment is completed. Here, the first image region may be an image region having a small area of the two image regions. In this way, when the ratio of the areas between the two image regions is not within the preset threshold interval, the partial contour corresponding to the image region with the smaller area of the two image regions is deleted, and the contour line formed by the newly added contour and the partial contour corresponding to the image region with the larger area of the two image regions can be used as the adjusted contour line. Therefore, partial contour of the original contour line of the target area can be deleted through the drawn new contour, the operation is simple, and the contour adjusting efficiency is improved.

The following describes an image processing method provided by an embodiment of the present disclosure by way of an example. FIG. 6 shows a schematic diagram of an example of an image processing interface according to an embodiment of the present disclosure.
