[0045] An embodiment of the present invention provides a method for implementing a rotation and distortion video transition effect and related equipment. The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] See Figure 1 A first aspect of the present invention provides a method for implementing a rotation and distortion video transition effect, the method comprising:

[0047] S100, obtaining a video clip for which a rotation and distortion video transition effect is to be produced; generally speaking, an edited video is composed of multiple video clips, and a transition effect is generally set at the joining position of two video clips;

[0048] S200, intercepting several image frames at the head or tail of the video clip; transition effects are generally set at the head or tail of a video clip, so when adding transition effects, they need to be added to the image frames at the head or tail of the video clip. The number of image frames to which the transition effects need to be added depends on the required duration of the transition effects and the playback frame rate of the video clip; the special effects in the present invention are directly created on the image frames, if the size of the video clip is not significantly increased;

[0049] S300, determining the center point position of the rotation and distortion video transition effect in each of the image frames and the range radius of the rotation and distortion video transition effect; in the present invention, in order to obtain a better viewing experience, the position of the rotation and distortion video transition effect on each image frame is variable, that is, the center point position in each of the image frames is different. Exemplarily, in several of the image frames, the center position of the rotation and distortion video transition effect moves linearly. For example, in the first image frame, the row and column coordinates of the center position of the rotation and distortion video transition effect are the second row and second column; in the second image frame, the row and column coordinates of the center position of the rotation and distortion video transition effect are the fifth row and fifth column; in the third image frame, the row and column coordinates of the center position of the rotation and distortion video transition effect are the tenth row and tenth column. In another embodiment, the center point position of the rotation and distortion video transition effect in each of the image frames may also change in a curve;

[0050] At the same time, the range radius of the rotation and distortion video transition effect on each image frame also changes. For example, in several image frames, the range radius of the rotation and distortion video transition effect gradually increases based on the timestamp of the image frame. Alternatively, it may decrease. The gradual increase or decrease may be based on a certain ratio. The software program provided by the solution of the present invention can provide different modes for users to choose.

[0051] S400, acquiring all pixels within the range radius of each image frame; in the present invention, rotational distortion only changes all pixels within the range radius of the image frame, while pixels outside the range radius remain unchanged;

[0052] S500: Rotate all the pixels within the range radius of each image frame with the center point as the center, wherein the farther the pixel is from the center point, the smaller the rotation angle of the pixel is. In another optional embodiment of the present invention, the farther the pixel is from the center point, the larger the rotation angle of the pixel is, thereby achieving different distortion effects.

[0053] S600: Performing blurring and smoothing processing on the pixel values of each pixel point within the range radius of each image frame after the rotation change, thereby obtaining a plurality of target image frames having the rotational distortion video transition effect. In the present invention, if only the pixel position is simply moved, there may be certain aliasing or moiré patterns between the pixels after the movement, so the present invention also requires blurring and smoothing processing on the pixel values after the pixel points are moved.

[0054] S700: Reinserting the plurality of target image frames into the video clip in their original order to obtain a video clip having the twirl video transition effect. Finally, the plurality of target image frames having the twirl video transition effect, which are produced by the plurality of image frames at the head or tail of the video clip of the present invention, are placed back into the head or tail of the video clip in their original order to reassemble the video clip into a complete video clip.

[0055] In an optional implementation manner of the first aspect of the present invention, rotating all the pixels within the range radius of each image frame about the center point position includes:

[0056] Establishing a two-dimensional coordinate system with the center point as the origin; in this step, the two-dimensional coordinate system is established with the pixel point at the center point;

[0057] Obtaining the initial coordinates (X, Y) of each pixel point in the two-dimensional coordinate system; after the two-dimensional coordinate system is established, it is necessary to obtain the coordinate system coordinates of each pixel point in the two-dimensional coordinate system according to the row and column information of each pixel point; specifically, this step is to, for any pixel point, first use any corner of the image frame as the origin, for example, use the lower left corner of the image frame as the origin, obtain the first row and column coordinates (a, b) of the center point position in the image frame and the second row and column coordinates (c, d) of the pixel point in the image frame; then, based on the first row and column coordinates (a, b) and the second row and column coordinates (c, d), calculate the initial coordinates (X, Y) of the pixel point in the two-dimensional coordinate system, where X=ca, Y=db;

[0058] Then through the formula Calculate the rotation angle of each pixel point, where Sr is the rotation angle, S is a set angle (an angle value set manually, which can be the same or different in different image frames), and r is the range radius of the rotation and distortion video transition effect;

[0059] Finally, the center point position is used as the center of the circle and each pixel point is rotated and moved based on the rotation angle. Specifically, this step is: for any pixel point, based on the rotation angle Sr, first calculate the target coordinates (Sx, Sy) of the pixel point in the two-dimensional coordinate system, where Sx = X*cos(Sr)-Y*sin(Sr), Sy = X*sin(Sr)-Y*cos(Sr); then convert the target coordinates (Sx, Sy) into the third row and column coordinates (e, f), where e = Sx+a, f = Sy+b; and according to the pixel point, move from the second row and column coordinates (c, d) to the third row and column coordinates (e, f) to complete the rotation movement of the pixel point.

[0060] As is well known, a video is composed of many frames of images, and an image is composed of many rows and columns of pixel values. The method of the present invention is to rotate each pixel on the image to another position according to a certain angle and rearrange the pixels to obtain a chaotic image. This image will definitely have many jagged edges. The second step of the present invention is to deal with the jagged edge problem. In an optional implementation of the first aspect of the present invention, it is necessary to perform fuzzy smoothing processing on the pixel values of each pixel point within the range radius of each image frame after the rotation change. Exemplarily, the fuzzy smoothing processing on the pixel values of each pixel point within the range radius of each image frame after the rotation change includes:

[0061] For any pixel point within the range radius of each image frame, obtaining a pixel value of the pixel point and pixel values corresponding to eight surrounding pixel points surrounding the pixel point;

[0062] Calculate the average of the sum of the pixel values of the pixel point and the eight surrounding pixel points, and use the average as the pixel value of the pixel point after fuzzy smoothing processing.

[0063] In general, the complete process steps and principles of the method for implementing the rotation and distortion video transition effect of the present invention can be summarized as follows:

[0064] 1. Coordinate pixel positions

[0065] Each pixel on an image has a position on the image, assuming it is (clos, rows), where clos represents the number of pixel columns and rows represents the number of pixel rows. To facilitate calculations, we can set a coordinate origin, assuming that the number of columns of the coordinate origin on the image is clo, and the number of columns on the image is row. The position of each pixel is converted based on this coordinate origin. The calculation method for converting the pixel position to coordinates (x, y) is as follows: x = clos - clo, y = rows - row;

[0066] 2. Rotate pixel coordinates

[0067] Generally, for a coordinate point (a, b) rotated around the origin by angle k, the coordinates (c, d) are calculated as follows: c = a*cos(k) - b*sin(k), d = a*sin(k) + b*cos(k);

[0068] Therefore, the calculation method is the same for rotating all pixel coordinates separately. Assuming the initial rotation angle is s, in order to achieve controllability, the range radius of the rotation change is set to r. No rotation is performed for places beyond the radius r from the origin, that is, the rotation angle is zero. According to the pixel coordinates obtained in step 1, the relationship between the actual rotation angle (assuming it is sr) and the radius r can be obtained as follows:

[0069] sr=s*(1.0-((x 2 +y 2 ) 1 / 2 ) / r), this formula indicates that the farther from the center, the smaller the rotation angle. It should be noted that if sr is less than 0, then it is only 0 and cannot be a negative value.

[0070] Next, according to the rotation formula, the rotated pixel coordinates (sx, sy) can be calculated as follows:

[0071] sx=x*cos(sr)-y*sin(sr)

[0072] sy=x*sin(sr)+y*cos(sr)

[0073] This completes the rotation.

[0074] 3. Convert pixel coordinates back to the position on the image

[0075] The previous step has obtained the rotated pixel coordinates (sx, sy). This coordinate is in the established coordinate system. Reading the pixel point requires the position information of the pixel on the image, so this time it needs to be converted into the pixel position (clos', rows'): clos' = sx + clo, rows' = sy + row;

[0076] 4. Blur and smooth the image to eliminate aliasing

[0077] In the previous step, the pixel position of the rotated image has been obtained, and the pixel point can be obtained from the image. However, the rotated image is bound to have aliasing and burrs, which greatly affects the appearance. Based on the principle that blurring and smoothing an image can eliminate aliasing, you can consider blurring. If you blur the image obtained after the above rotation, the blurred image will have a certain degree of blurriness and may not be clear. This will blur the entire image to eliminate aliasing, which is not the desired result. Therefore, a solution here is to integrate blurring into the rotation change, so that the aliasing caused by the change can be eliminated during the rotation change without affecting the image quality.

[0078] Generally, there are many ways to blur an image. Here we only take the simplest method, mean blur: for each pixel, its pixel value is the average of the pixel values of the nine pixels in the nine-square grid centered on it, and the mean blur is completed.

[0079] Therefore, here, we can get the position of the pixel on the image (clos', rows') through the previous step, and get the pixel positions in the nine-square grid centered on it as follows: (clos'-1, rows'-1), (clos', rows'-1), (clos'+1, rows'-1), (clos'-1, rows')(clos', rows')(clos'+1, rows')(clos'-1, rows'+1), (clos', rows'+1), (clos'+1, rows'+1); take the pixel values of these 9 positions respectively and then average them to achieve the purpose of using blur to eliminate aliasing.
