The electronic devices in the embodiments of the present invention include, but are not limited to, mobile terminals such as smart phones, notebook computers, PAD (tablet computer), etc., and fixed terminals such as digital TVs, desktop computers, etc.
The invention is described in further detail below with reference to the figures and specific examples.
Example one
Fig. 1 is a schematic diagram of an implementation flow of an image processing method according to an embodiment of the present invention, applied to an electronic device, as shown in fig. 1, the implementation flow of the image processing method according to the embodiment of the present invention includes:
step 101: the first image is loaded and displayed.
Here, the first image is any image selected by the user and required to be subjected to image area processing, and as shown in fig. 2a, a schematic diagram of the first image to be processed loaded and displayed in the embodiment of the present invention is shown.
Step 102: and detecting a first operation of forming a closed curve track on the first image, and taking an area image in the closed curve track as a target area image.
In an embodiment, the first operation may be any operation of forming a closed curve track on the first image, and the closed curve track may be a closed curve track formed by a smooth curve of any shape drawn by a user, such as a circle, an ellipse, and the like; fig. 2b is a schematic image diagram of a closed curve path according to an embodiment of the present invention.
Step 103: a second operation is detected that forms a non-closed curved trajectory on the first image.
Here, the non-closed curve track and the closed curve track have at least two intersection points, the non-closed curve track may be a curve or a straight line intersecting the closed curve track, and correspondingly, the second operation may be an operation of drawing the curve or the straight line intersecting the closed curve track on the first image by the user; fig. 2c is a schematic diagram of an image of a non-closed curve trace and a closed curve trace with two intersections according to an embodiment of the present invention.
Step 104: determining an operation type of the second operation based on the relative position information of the non-closed curve trajectory and the position information of the intersection point.
In actual implementation, the operation types of the second operation may be set as two types, namely, a first operation type and a second operation type; wherein the first operation type is used for indicating the reduction of the image area of the target area image (namely the area image in the closed curve track); the second operation type is used for indicating the expansion of the image area of the target area image; the reduction and expansion described here are not image reduction and expansion of the target area image, but deletion or increase of the area size of the area where the target area image is located.
Since there are at least two intersections between the non-closed curve track and the closed curve track, and a curve is formed between two adjacent intersections on the non-closed curve track, if a curve is extracted from two adjacent intersections, at least one curve can be extracted from the non-closed curve, and each curve extracted from the non-closed curve can form a different relative position relationship with the closed curve track, such as being located inside the closed curve track or being located outside the closed curve track, and the different position relationship can correspond to a different operation type, such as a first operation type when the curve is located inside the closed curve track and a second operation type when the curve is located outside the closed curve track, in the embodiment of the present invention, as shown in fig. 2c, there are two intersections between the non-closed curve track and the closed curve track, and the curve between the two intersections is located inside the closed curve track, therefore, it is determined that a reduction of the image area is required for the target area image (i.e., the area image within the closed curve trajectory).
Step 105: and adjusting the image area of the target area image according to the operation type.
In the embodiment of the present invention, if the curve trajectory between two intersections formed by the non-closed curve trajectory and the closed curve trajectory is a third curve trajectory, as shown in fig. 2d, it can be seen from fig. 2d that the third curve trajectory divides the target area image into the first area image and the second area image, and the second operation corresponds to the first operation type, so that performing image area adjustment on the target area image may be to reduce the image area where the target area image is located, and may be to delete the first area image or the second area image, which may specifically be preset by a user, such as presetting an image with a default deleted area having a smaller area, as shown in fig. 2 e; or, in actual implementation, the first area image and the second area image are identified by different display effects, and a prompt message is generated and displayed for prompting a user to give an instruction to delete the first area image or the second area image from the target area image, that is, the user determines which image area to delete, as shown in fig. 2f, if the user selects image 1, the image after area adjustment on the target image area is 2 e; the different display effects may be any display effects that can distinguish the first area image from the second area image, such as filling different colors, filling different patterns, and the like.
By applying the embodiment of the invention, when the user selects the image, the user only needs to draw a closed curve track graph on the image to be processed firstly to determine the target image, and then draws a non-closed curve track graph to be crossed with the closed curve track graph based on the target image to form at least two cross points, so that the image area of the area where the target image is located can be automatically increased or reduced according to the relative position relation between the closed curve drawn by the user and the non-closed curve, the user does not need to enter a special image area increasing or subtracting mode, the operation is simple and convenient, and the user experience is good.
Example two
Fig. 3 is a schematic diagram of an implementation flow of an image processing method according to an embodiment of the present invention, which is applied to an electronic device, and as shown in fig. 3, the implementation flow of the image processing method according to the embodiment of the present invention includes:
step 301: the first image is loaded and displayed.
Here, the first image is any image selected by the user and required to be subjected to image area processing, and as shown in fig. 4a, a schematic diagram of the first image to be processed loaded and displayed in the embodiment of the present invention is shown.
Step 302: and detecting a first operation of forming a closed curve track on the first image, and taking an area image in the closed curve track as a target area image.
In an embodiment, the first operation may be any operation of forming a closed curve track on the first image, and the closed curve track may be a closed curve track formed by a smooth curve of any shape drawn by a user, such as a circle, an ellipse, and the like; fig. 4b is a schematic image diagram of a closed curve path according to an embodiment of the present invention.
Step 303: a second operation is detected that forms a non-closed curved trajectory on the first image.
Here, the non-closed curve track and the closed curve track have at least two intersection points, the non-closed curve track may be a curve or a straight line intersecting the closed curve track, and correspondingly, the second operation may be an operation of drawing the curve or the straight line intersecting the closed curve track on the first image by the user; fig. 4c is a schematic diagram of an image of a non-closed curve trace and a closed curve trace with two intersections according to an embodiment of the present invention.
Step 304: and detecting that two intersection points exist between the non-closed curve track and the closed curve track, and extracting a curve track between the two intersection points from the non-closed curve track as a third curve track.
It should be noted that, in the embodiment of the present invention, there are two intersection points between the non-closed curve track and the closed curve track, however, in practical applications, there may also be more than two intersection points between the non-closed curve track and the closed curve track, such as 3, 4, 6, etc., and when there are more than two intersection points, two adjacent intersection points on the non-closed curve track may extract a curve.
Step 305: judging the relative position relationship between the third curve track and the closed curve track, and executing step 306 if the third curve track is positioned in the closed curve track; if the third curved track is outside the closed curved track, go to step 308.
In practical implementation, the different position relationships between the third curve track and the closed curve track correspond to different operation types of the second operation, and when the third curve track is located in the closed curve track, the operation type is the first operation type; the first operation type is used for indicating the reduction of the image area of the target area image; when a third curved track is outside the closed curved track, the operation type is a second operation type; the second operation type is used for indicating the expansion of the image area of the target area image; the reduction and expansion described here are not image reduction and expansion of the target area image, but deletion or increase of the area size of the area where the target area image is located.
Step 306: and marking the first area image and the second area image by using different display effects, and generating and displaying first prompt information.
Here, the first area image and the second area image are the first area image and the second area image into which the target area image is divided by the third curve track;
the different display effects may be any display effects that can distinguish the first area image from the second area image, such as filling different colors, filling different patterns, and the like.
The first prompt message is used for prompting the user to give an instruction for deleting the first area image or the second area image from the target area image, namely prompting the user to decide which image area to delete by the user.
Step 307: and receiving and responding to an image deleting instruction, and adjusting the image area of the target area image.
Here, the image deletion instruction is an instruction given by the user to delete the first area image or the second area image; and responding to the instruction, and performing image area adjustment on the target area image to delete the first area image or the second area image.
Step 308: and combining the third area image and the target area image into one area image.
Here, the third area image is an area image which is formed by a curve track between two intersection points in the closed curve track and the third curve track and is positioned outside the target area image; as shown in fig. 4 c.
Combining a third area image and the target area image into an area image, namely, increasing/expanding the image area of the target area image, wherein the size of the increased image area is the size of the image area where the third area image is located; as shown in fig. 4 d.
Step 309: and ending the processing flow.
In the embodiment of the invention, taking a closed curve track and a non-closed curve track as an example, when a user selects an image, the user only needs to draw a closed curve track graph on the image to be processed to determine a target image, and then draws a non-closed curve track graph and the closed curve track graph to form two intersections based on the target image, so that if a curve between the two intersections on the non-closed curve track is positioned outside the closed curve track, the target image area can be directly increased, and if a curve between the two intersections on the non-closed curve track is positioned inside the closed curve track, a prompt message is generated to enable the user to determine the deleted image area, which is more humanized, and the user does not need to enter a special image area increasing or subtracting mode, the user experience is improved.
EXAMPLE III
Fig. 5 is a schematic diagram of an implementation flow of an image processing method according to an embodiment of the present invention, which is applied to an electronic device, and as shown in fig. 5, the implementation flow of the image processing method according to the embodiment of the present invention includes:
step 501: the first image is loaded and displayed.
Here, the first image is any image selected by the user and required to be subjected to image area processing, and as shown in fig. 6a, a schematic diagram of the first image to be processed loaded and displayed in the embodiment of the present invention is shown.
Step 502: and detecting a first operation of forming a closed curve track on the first image, and taking an area image in the closed curve track as a target area image.
In an embodiment, the first operation may be any operation of forming a closed curve track on the first image, and the closed curve track may be a closed curve track formed by a smooth curve of any shape drawn by a user, such as a circle, an ellipse, and the like; fig. 6b is a schematic image diagram of a closed curve path according to an embodiment of the present invention.
Step 503: a second operation is detected that forms a non-closed curved trajectory on the first image.
Here, the non-closed curve track and the closed curve track have at least two intersection points, the non-closed curve track may be a curve or a straight line intersecting the closed curve track, and correspondingly, the second operation may be an operation of drawing the curve or the straight line intersecting the closed curve track on the first image by the user; fig. 6c is a schematic diagram of an image of a non-closed curve trace and a closed curve trace with three intersections according to an embodiment of the present invention.
Step 504: and detecting that three intersection points exist between the non-closed curve track and the closed curve track, extracting a curve track between the first intersection point and the second intersection point from the non-closed curve track as a third curve track, and extracting a curve track between the second intersection point and the third intersection point as a fourth curve track.
It should be noted that, if it is detected that N intersections exist between the non-closed curve trajectory and the closed curve trajectory, where N is a positive integer greater than 2, a curve trajectory between the first intersection and the second intersection is sequentially extracted from the non-closed curve trajectory as a third curve trajectory, and a curve trajectory between the second intersection and the third intersection is extracted as a fourth curve trajectory until a curve trajectory between the N-1 th intersection and the N-th intersection is extracted as an N +1 th curve trajectory.
Step 505: it is detected that the third curved track is located inside the closed curved track and the fourth curved track is located outside the closed curved track.
In practical implementation, if N intersections exist between a non-closed curve track and a closed curve track, where N is a positive integer greater than 2, the relative position relationship between the third curve track and the fourth curve track, and up to the N +1 th curve track and the closed curve track, needs to be determined respectively.
And different position relations between a curve track extracted from a non-closed curve track and a closed curve track correspond to different operation types of the second operation, if the curve track is positioned in the closed curve track, the corresponding curve track corresponds to the first operation type and indicates that the image area of the target area image is reduced, and if the curve track is positioned outside the closed curve track, the corresponding curve track corresponds to the second operation type and indicates that the image area of the target area image is expanded. As shown in fig. 6d, the third curved track is located inside the closed curved track, and the fourth curved track is located outside the closed curved track, that is, the image area increasing and decreasing operations need to be performed on the target image area at the same time.
Step 506: and determining that the first image area is smaller than the second image area, deleting the first image area, and combining the second image area and the third image area into a fourth image area.
Here, the first image area and the second image area are a first image area and a second image area into which the target image area is divided by the third curve track; the third image area is an image area which is formed by the fourth curve track and the closed curve track and is positioned outside the target image area.
In the embodiment of the present invention, the image area with a smaller area is deleted by default when the image area deletion operation is performed, but in practical applications, a prompt message for prompting the user to give an instruction to delete the first area image or the second area image from the target area image may also be generated, and the user determines which image area to delete. Fig. 6e is a schematic diagram illustrating the region of the target image region after being adjusted according to the embodiment of the present invention.
Step 507: and identifying background image information of the fourth image area, and adjusting the transparency of the identified background image according to the preset background transparency.
Here, the background transparency of the region image may be set according to actual needs, for example, the background transparency is set to 100%, so that when the user inserts the fourth region image into a certain position in another image according to actual needs, the insertion effect is more desirable, as shown in fig. 6 f.
