Detailed Description
The following further describes specific implementation of the embodiments of the present invention with reference to the drawings.
Example one
An embodiment of the present application provides an image processing method, which is applied to an image processing apparatus, where the image processing apparatus may be a computer, a notebook, an intelligent terminal, or an image processing unit installed on an electronic device, for example, an image processing unit installed on an unmanned aerial vehicle controller, an image processing unit installed on a camera device, and the like, and the image processing apparatus may also be a pan-tilt apparatus. As shown in fig. 1, fig. 1 is a flowchart of an image processing method according to an embodiment of the present application. The image processing method comprises the following steps:
101. and generating a transition image frame sequence according to the first group of image frames, the second group of image frames and a preset switching effect.
The first group of image frames belongs to a first image frame sequence and the second group of image frames belongs to a second image frame sequence. The first image frame sequence and the second image frame sequence may be a video (continuous image frame sequence) or a set of related pictures (discrete image frame sequence). Each of the first group of image frames and the second group of image frames may include at least one image frame, and for example, when the number of image frames included in the first group of image frames is greater than or equal to 2, at least two image frames included in the first group of image frames are sorted according to the playing order of the video or the image.
The switching effect refers to a playing display effect of a transition part between two image frame sequences during playing, in this application, the preset switching effect is a playing display effect of a transition part between a first image frame sequence and a second image frame sequence, and the preset switching effect may include: translation, rotation, magnification, reduction, etc.
Alternatively, in the first application scenario, the preset switching effect may be determined before step 101, here, how to determine the preset switching effect is illustrated.
Optionally, in an embodiment of the present application, the method further includes: the preset switching effect is determined based on at least one of a shape and a variation of a first key image element in the first set of image frames.
Further, a preset switching effect is determined according to a change condition of a first key image element in the first group of image frames and a preset mapping, the preset switching effect may also be determined according to a shape of the first key image element in the first group of image frames and the preset mapping, and the preset switching effect may also be determined according to the preset mapping by combining the shape and the change condition of the first key image element. The preset map is used for indicating the corresponding relation between the change condition of the at least one image element and the at least one switching effect, and can also indicate the corresponding relation between the shape of the at least one image element and the at least one switching effect.
It should be noted that the variation of the first key image element in the first group of image frames includes position variation, size variation (i.e. pixel area variation), shape variation, etc., and here, two specific examples are listed to illustrate how to determine the preset switching effect.
For example, in a first example, when the first group of image frames is ordered in the playing order, the position of the first key image element changes from left to right in the horizontal direction, and the preset switching effect may be determined to be a left to right translation in the horizontal direction.
For another example, in the second example, when the first group of image frames are sorted according to the playing order, the area occupied by the first key image element changes from small to large, and it may be determined that the preset switching effect is amplification.
Of course, this is merely an example and does not represent a limitation of the present application.
Optionally, in a second application scenario, it is illustrated how the first set of image frames and the second set of image frames are determined.
Optionally, in an embodiment of the present application, the method further includes:
and determining a first group of image frames in the first image frame sequence according to at least one of a preset frame number, a preset time length and the area of the key object.
Similarly, the second group of image frames may also be determined in the second image frame sequence according to at least one of a preset number of frames, a preset time length, and an area of a key object.
Here, taking the example that the first image frame sequence is played before the second image frame sequence as an example, for example, if the preset frame number is 10, the last 10 image frames in the first image frame sequence may be determined as the first group of image frames in the image frame playing order, and of course, the 10 image frames in the starting position in the second image frame sequence may also be determined as the second group of image frames in the image frame playing order; for another example, after determining the key object in the first image frame sequence, n consecutive image frames in the first image frame sequence, in which the area of the tail key object exceeds the preset area, are determined as the first group of image frames in the image frame playing order, where n is an integer greater than or equal to 1. Of course, this is merely an example, and does not represent a limitation of the present disclosure, and there may be various implementations as to how to determine the first set of image frames and the second set of image frames, which is not limited in this application.
Alternatively, in a third application scenario, it is illustrated how a sequence of transition image frames is generated.
Optionally, in an embodiment of the present application, generating the transition image frame sequence according to the first group of image frames, the second group of image frames, and the preset switching effect includes:

It should be noted that at least one image frame in the first group of image frames may be the last m image frames of the first group of image frames sorted in the playing order, m is an integer greater than or equal to 1, and m is less than or equal to the number of frames of the first group of image frames.
Here, two specific examples are listed for explanation:

For image frame a, the 1/3 on the right side in image frame a is deleted and the rest 2/3 is moved to the rightmost side to obtain image frame a', that is, the pixels with x coordinate greater than 2w/3 in image frame a are deleted and the rest x coordinate is increased by w/3; the left 1/3 in image frame c is then added to the region 1/3 left free by image frame a' to yield the 1 st transition image frame.
For image frame b, the 2/3 on the right side in image frame b is deleted and the remaining 1/3 is moved to the far right to get image frame b', that is, the pixels in image frame b with x coordinate larger than w/3 are deleted and the x coordinate of the remaining pixels is increased by 2 w/3; the 2/3 on the left in image frame c is then added to the region 2/3 left free of image frame b' to get the 2 nd transition image frame.
In a second example, as shown in fig. 3, fig. 3 is a schematic diagram of a switching effect provided in an embodiment of the present application, where m is 2, the preset switching effect includes an enlargement as an example, a first key image element included in a first group of image frames, in which a 2 nd last image frame and a last image frame are an image frame a and an image frame b, respectively, presents an enlargement effect when playing.
For image frame a, the second key image element in the second group of image frames is reduced to 1/3 with the original size to obtain key image element c1The key image element c1The 1 st transition image frame is obtained by adding the center position of the first key image element in the image frame a.
For image frame b, the second key image element in the second group of image frames is reduced to 2/3 of the original size to obtain key image element c2The key image element c2The 2 nd transition image frame is obtained by increasing the center position of the first key image element in image frame b.
Of course, this is only illustrated by two examples, and does not represent that the present application is limited thereto.
In connection with the above-described first, second and third application scenarios, a first key image element, a key object and a second key image element are explained here. The first key image element and the key object may indicate the same object or may indicate two different objects. Here, taking the first key image element as an example, two specific implementations are listed, and how to determine the key object, the first key image element, or the second key image element is described in detail.
In a first implementation manner, a target image frame is divided into at least one region, the target image frame is any one image frame in a first group of image frames, each region is compared with image elements in a database, image elements included in the target image frame are determined, the image elements included in the first group of image frames with the largest number are determined as first key image elements, and the image elements included in the first group of image frames with the largest area can also be determined as first key image elements;
in a second implementation manner, at least one image element is determined in the target image frame according to a pixel value, where the pixel value may be an RGB component or a gray value, and this application is not limited to this, and in the target image frame, if a difference value between the RGB components of one pixel and an adjacent pixel exceeds a preset threshold, the pixel is marked as a contour pixel, a shape of the at least one image element is determined according to pixel coordinates of all contour pixels, an image element with the largest number included in the first group of image frames is determined as a first key image element, and an image element with the largest area included in the first group of image frames may also be determined as a first key image element.
102. A transition image frame sequence is inserted between the first image frame sequence and the second image frame sequence.
According to the playing order of the first image frame sequence and the second image frame sequence, two examples are listed here for illustration:

The image frames to be replaced may include image frames in the first set of image frames and may also include image frames in the second set of image frames. The image frame to be replaced is an image frame to which key image elements are added, for example, if A, B, C image frames are determined in the first group of image frames and the second key image element in the second group of image frames is inserted into the image frames A, B and C, the image frame A, B, C is the image frame to be replaced.
