Detailed Description

Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Fig. 1 shows a flow diagram of a video processing method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes steps S11 through S13.

In step S11, a reflection area in a video frame to be processed of the video is determined.

The video of the embodiments of the present disclosure may be any video that needs to be processed. For example, the video of the embodiment of the present disclosure may be a video shot in non-real time, and may also be a video shot in real time. The video frames to be processed of the video represent the video frames in the video that need to be processed. In the embodiment of the present disclosure, a part of video frames of a video may be used as video frames to be processed, and all video frames of the video may also be used as video frames to be processed. For a non-real-time shot video, whether each video frame of the video is a video frame to be processed or not can be determined in advance according to the frame number of each video frame of the video in the video; for the video shot in real time, whether each video frame of the video is a video frame to be processed or not can be determined in real time according to the frame number of each video frame of the video in the video.

The frame number of the video frame to be processed in the video indicates that the video frame to be processed is the number of frames in the video. For example, the frame number of the video frame to be processed in the video is p, which indicates that the video frame to be processed is the p-th frame in the video. For both non-live captured video and live captured video, the number of frames in the video of the video to be processed can be counted from the first frame of the video.

In one possible implementation, the preset reflection area may be used as the reflection area in the video frame to be processed. In this implementation, the size and position of the reflection region and the non-reflection region in each video frame may be set in advance, thereby determining the reflection region in the video frame to be processed.

In another possible implementation manner, the reflection area in the video frame to be processed may be determined according to an instruction for selecting the reflection area. In the implementation mode, the user can select the reflection area in the video frame to be processed according to the actual application scene requirement and/or personal preference, so that the personalized requirement of the user is met.

In another possible implementation, a boundary between a water surface and a non-water surface in the video frame to be processed may be identified, and a reflection area in the video frame to be processed may be determined according to the boundary and the position of the water surface. In this implementation, if the video frame to be processed includes a water surface, a boundary between a water surface and a non-water surface in the video frame to be processed may be identified, and a reflection region in the video frame to be processed may be determined according to the boundary and a position of the water surface. According to the implementation mode, the inverted image area in the video frame to be processed can be automatically determined, and the accuracy is high.

In step S12, an initial reflection image corresponding to the reflection region is determined.

In the embodiment of the present disclosure, the initial reflection image corresponding to the reflection region may be determined according to the image of the non-reflection region, so as to achieve an effect of displaying the reflection of the image content of the non-reflection region in the reflection region.

In step S13, the coordinates of the pixels in the initial reflection image are changed according to the number of the video frames to be processed in the video, so as to obtain a water ripple reflection image corresponding to the initial reflection image, and the water ripple reflection image is used as the image of the reflection area.

In the embodiment of the present disclosure, since the number of frames in the video of each to-be-processed video frame is different, the coordinates of the pixels in the initial reflection image are changed based on the number of frames in the video of the to-be-processed video frame, and the degree of change of the corresponding changed coordinates of each to-be-processed video frame is also different. As the frame number of the video frame to be processed in the video changes, the ripple effect in different video frames to be processed moves along the axial direction, so that the water flow ripple effect is generated, and the ripple can present irregular ripple.

In one possible implementation, the abscissa of the pixel in the initial reflection image may be changed according to the number of frames of the video frame to be processed in the video.

The method and the device for processing the water ripple image have the advantages that the inverted image area in the video frame to be processed of the video is determined, the initial inverted image corresponding to the inverted image area is determined, the coordinates of the pixels in the initial inverted image are changed according to the frame number of the video frame to be processed in the video, the water ripple inverted image corresponding to the initial inverted image is obtained, and the water ripple inverted image is used as the image of the inverted image area, so that the water ripple inverted image effect can be achieved in the video through low calculation complexity, the effect is real, and the real-time requirement of video processing is met.

Fig. 2 shows a flowchart of video processing method step S12 according to an embodiment of the present disclosure. As shown in fig. 2, step S12 may include step S121 and step S122.

In step S121, the image of the non-inverted area in the video frame to be processed is vertically inverted to obtain an inverted image, where the non-inverted area represents an area outside the inverted area in the video frame to be processed.

Fig. 4 shows a schematic diagram of a reflection region and a non-reflection region in a video frame to be processed in a video processing method according to an embodiment of the present disclosure. In the example shown in fig. 4, the reflection area 41 is above the video frame to be processed, and the non-reflection area 42 is below the video frame to be processed. In other examples, the reflection area is below the video frame to be processed, and the non-reflection area is above the video frame to be processed.

Fig. 5 illustrates a schematic diagram of flipping an image in a video processing method according to an embodiment of the present disclosure. The inverted image in fig. 5 is obtained by vertically inverting the image of the non-inverted area 42 in fig. 4.

In step S122, an initial reflection image corresponding to the reflection region is determined from the inverted image.

In a possible implementation manner, determining an initial reflection image corresponding to the reflection region according to the reversed image includes: and if the height of the reversed image is equal to that of the reflection area, taking the reversed image as an initial reflection image corresponding to the reflection area.

In another possible implementation manner, determining an initial reflection image corresponding to the reflection region according to the flipped image includes: and performing telescopic processing on the reversed image in the vertical direction according to the height of the reflection area, so that the height of the reversed image after telescopic processing is equal to the height of the reflection area, and obtaining an initial reflection image corresponding to the reflection area. In the implementation mode, if the height of the reversed image is greater than that of the reflection region, the reversed image is compressed in the vertical direction, so that the height of the compressed reversed image is equal to that of the reflection region, and an initial reflection image corresponding to the reflection region is obtained; and if the height of the reversed image is smaller than that of the reflection area, stretching the reversed image in the vertical direction to enable the height of the stretched reversed image to be equal to that of the reflection area, and obtaining an initial reflection image corresponding to the reflection area. Fig. 6 illustrates a schematic diagram of an initial reflection image in a video processing method according to an embodiment of the present disclosure. According to this implementation, the reflection of the image of the entire non-reflection area can be displayed in the reflection area.

In another possible implementation manner, determining an initial reflection image corresponding to the reflection region according to the flipped image includes: and if the height of the reflection area is smaller than that of the reversed image, intercepting the image of the reversed image with the same height as that of the reflection area on the boundary line side as an initial reflection image corresponding to the reflection area. In this implementation, the portion of the inverted image on the boundary line side represents the portion of the original inverted image that is connected to the inverted region. For example, if the reflection area is above the video frame to be processed and the non-reflection area is below the video frame to be processed, then the image with the same height as the reflection area on the boundary side of the reversed image is captured, which means that the image with the same height as the reflection area below the reversed image is captured; if the inverted image is below the video frame to be processed and the non-inverted image is above the video frame to be processed, intercepting the image of which the height of the inverted image on the boundary side is the same as that of the inverted image refers to intercepting the image of which the height above the inverted image is the same as that of the inverted image. Fig. 7 shows another schematic diagram of an initial reflection image in a video processing method according to an embodiment of the present disclosure.

Fig. 8 shows an exemplary flowchart of a video processing method in step S13 according to the frame number of the video frame to be processed in the video, changing the coordinates of the pixels in the initial inverted image, and obtaining a water ripple inverted image corresponding to the initial inverted image. As shown in fig. 8, changing the coordinates of the pixels in the initial inverted image according to the number of the video frames to be processed in the video to obtain the moire inverted image corresponding to the initial inverted image may include steps S131 and S132.

In step S131, an offset coefficient corresponding to the video frame to be processed is determined according to the frame number of the video frame to be processed in the video.

In a possible implementation manner, determining an offset coefficient corresponding to a video frame to be processed according to a frame number of the video frame to be processed in the video includes: and calculating a remainder obtained by dividing the frame number of the video frame to be processed in the video by the total frame number of the preset period, wherein the remainder is used as an offset coefficient corresponding to the video frame to be processed.

For example, if the number of frames of the video frame to be processed in the video is p, the total number of frames of the preset period is T, and a remainder obtained by dividing p by T is T, then T may be used as the offset coefficient corresponding to the video frame to be processed.

In the embodiment of the present disclosure, as the number of frames of a video frame to be processed in the video changes, the offset coefficient corresponding to the video frame to be processed changes.

It should be noted that, although the determination manner of the offset coefficient is described above by taking the remainder obtained by dividing the number of frames of the to-be-processed video frame in the video by the total number of frames of the preset period as the offset coefficient corresponding to the to-be-processed video frame as an example, it can be understood by those skilled in the art that the present disclosure should not be limited thereto. The skilled person can flexibly set the mode of determining the offset coefficient corresponding to the video frame to be processed according to the actual application scene requirement and/or personal preference, as long as the mode is determined according to the frame number of the video frame to be processed in the video.

In step S132, the coordinates of the pixels in the initial inverted image are changed according to the offset coefficient corresponding to the video frame to be processed, so as to obtain a moire inverted image corresponding to the initial inverted image.

In the embodiment of the present disclosure, since the number of frames in the video of each to-be-processed video frame is different, the offset coefficient corresponding to each to-be-processed video frame is different. The degree of change in the coordinates is different based on the different offset coefficients.

In a possible implementation manner, changing coordinates of pixels in the initial inverted image according to an offset coefficient corresponding to a video frame to be processed to obtain a moire inverted image corresponding to the initial inverted image, includes: and changing the abscissa of the pixel in the initial inverted image according to the offset coefficient corresponding to the video frame to be processed to obtain the water ripple inverted image corresponding to the initial inverted image.

In a possible implementation manner, changing the abscissa of a pixel in an initial inverted image according to a shift coefficient corresponding to a video frame to be processed to obtain a water ripple inverted image corresponding to the initial inverted image, includes: and determining the abscissa of each changed pixel in the initial inverted image according to the offset coefficient corresponding to the video frame to be processed, the abscissa of each pixel in the initial inverted image and the ordinate of each pixel in the initial inverted image, so as to obtain the water ripple inverted image corresponding to the initial inverted image.

In a possible implementation manner, determining, according to an offset coefficient corresponding to a video frame to be processed, an abscissa of each pixel in an initial reflection image, and an ordinate of each pixel in the initial reflection image, a changed abscissa of each pixel in the initial reflection image, to obtain a moire reflection image corresponding to the initial reflection image, includes: and determining the horizontal coordinate of each changed pixel in the initial reflection image according to the offset coefficient corresponding to the video frame to be processed, the height of the video frame to be processed, the horizontal coordinate of each pixel in the initial reflection image and the vertical coordinate of each pixel in the initial reflection image, so as to obtain the water ripple reflection image corresponding to the initial reflection image.

The video frame to be processed is a static image, and the height of the video frame to be processed is the height of the static image.

In a possible implementation manner, the moire deformation function may be determined according to the offset coefficient corresponding to the video frame to be processed and the height of the video frame to be processed.

As one example of this implementation, the water ripple deformation function may be

y₂＝y₁. Wherein (x)₁,y₁) (x) is the pixel coordinate in the initial reflection image₂,y₂) Is the pixel coordinate in the water ripple reflection image, t represents the offset coefficient, h represents the height of the video frame to be processed, a₁、a₂And a₃Is a coefficient of₁、a₂And a₃Can be determined according to the actual application requirements. By using the water ripple deformation function, the coordinate (x) in the initial reflection image can be converted₁,y₁) As the coordinates (x) in the water-ripple-inverted image₂,y₂) The pixel value of (2).

For example, the water ripple deformation function is

Fig. 11 illustrates a schematic diagram of a water ripple reflection image as an image of a reflection region in a video processing method according to an embodiment of the present disclosure.

Fig. 12 shows an exemplary flowchart of a video processing method according to an embodiment of the present disclosure. As shown in fig. 12, the method may include steps S11 through S14.

In step S14, the video frame to be processed and the overlay layer are fused.

The superimposed layer may be any layer that needs to be fused with the video frame to be processed. For example, the overlay layer may have a water surface effect. The video frames to be processed are fused with the superposition with the water surface effect, so that the water surface texture effect of the video frames to be processed can be increased.

Fig. 13 shows an exemplary flowchart of step S14 of the video processing method according to the embodiment of the present disclosure. As shown in fig. 13, step S14 may include steps S141 to S143.

In step S141, a mask region in the superimposed layer is determined.

In the embodiment of the present disclosure, the masked region may represent a region that is not required to be fused with the video frame to be processed in the overlay layer, and the unmasked region may represent a region that is required to be fused with the video frame to be processed in the overlay layer.

In a possible implementation manner, the mask area in the overlay layer may be determined according to an instruction for selecting the mask area. According to the implementation mode, the mask area in the superposed layer can be determined according to the user requirement.

In another possible implementation manner, a preset mask region may be used as the mask region in the superimposed layer. In this implementation manner, the sizes and positions of the mask region and the unmasked region in the overlay layer may be preset, so as to determine the mask region in the overlay layer.

In step S142, the pixel value of the mask region is determined according to the pixel value of the superimposed layer.

In one possible implementation, the pixel values of the mask regions may be determined solely from the pixel values of the superimposed layer. For example, the pixel value of the superimposed layer may be taken as the pixel value of the corresponding coordinate in the mask region.

In step S143, a pixel value of a non-mask region is determined according to a pixel value of the video frame to be processed and a pixel value of the overlay layer, where the non-mask region represents a region outside the mask region in the overlay layer.

In the embodiment of the present disclosure, the pixel values of the non-mask region are determined by the pixel values of the video frame to be processed and the pixel values of the corresponding coordinates in the overlay layer.

In a possible implementation manner, determining a pixel value of a non-mask area according to a pixel value of a video frame to be processed and a pixel value of an overlay layer includes: and overlapping the video frame to be processed and the overlapped layer in the non-mask area in a positive bottom overlapping mode, and determining the pixel value of the non-mask area. For example, the pixel value of a coordinate on the non-mask area may be equal to the pixel value of the coordinate on the video frame to be processed × the pixel value of the coordinate on the overlay layer/255.

In a possible implementation manner, after the video frame to be processed and the overlay layer are fused, the processed video frame to be processed may be output to a screen in real time and displayed.

Because the embodiment of the disclosure can realize the water ripple reflection effect in the video through lower computation complexity, the embodiment of the disclosure can be applied to application scenes such as video recording and live broadcasting platforms and the like which need to process the video in real time.
