背景技术Background technique
随着短视频行业的快速发展，用户对美颜的需求不再仅仅局限于照片，越来越多的需求体现在视频中。现在很多视频类的平台或者视频剪辑都需要用到滤镜效果。如果接入滤镜效果，会提升视频色调风格，将镜头里的内容变得更有格调和满足用户视觉效果需求。With the rapid development of the short video industry, users' demand for beauty is no longer limited to photos, but more and more demands are reflected in videos. Nowadays, many video platforms or video editing require the use of filter effects. If you add a filter effect, it will improve the tone and style of the video, make the content in the shot more stylish and meet the user's visual needs.
目前，在对视频进行滤镜效果添加时，是以视频帧为单位进行滤镜添加，在添加滤镜时，对整张视频帧进行统一处理，即对整张视频帧添加同样的滤镜效果。Currently, when adding filter effects to videos, filters are added in units of video frames. When adding filters, the entire video frame is processed uniformly, that is, the same filter effect is added to the entire video frame. .
这种滤镜添加方式，只能添加一种滤镜效果，滤镜效果单一，进而使得视频特效较差，降低视频合成质量，无法满足用户的滤镜需求。This filter adding method can only add one filter effect, and the filter effect is single, which makes the video special effects poor, reduces the video synthesis quality, and cannot meet the user's filter needs.

Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
目前，在对视频帧添加滤镜效果时，是对整张视频帧进行统一处理，滤镜效果单一，特效效果展示差，难以适应内容中的多元化需求，无法满足用户的滤镜需求。Currently, when adding filter effects to video frames, the entire video frame is processed uniformly. The filter effect is single, the special effects display is poor, and it is difficult to adapt to the diversified needs in the content and cannot meet the filter needs of users.
为了解决这一技术问题，发明人经过研究发现，可以将视频帧进行分块处理，对分块的子视频帧动态添加滤镜，增加滤镜效果，提高特效效果，满足多元化需求，进而满足用户的滤镜需求。In order to solve this technical problem, the inventor found through research that video frames can be divided into blocks, and filters can be dynamically added to the divided sub-video frames to increase filter effects, improve special effects, meet diversified needs, and then satisfy User filter requirements.
具体的，本发明实施例提供了一种视频帧处理方法、装置及电子设备，获取目标视频中需要进行滤镜添加操作的视频帧，并将所述视频帧转化为预设格式的目标视频帧，对所述目标视频帧进行分块，得到多个子视频帧，按照所述多个子视频帧的排列顺序，动态设置所述子视频帧的边缘的灰度值为对应的目标灰度值，以及所述子视频帧的边缘的透明度为对应的目标透明度。即本发明中，对一个视频帧拆分得到的子视频帧动态添加滤镜，增加滤镜效果，进而提高视频特效，提高视频合成质量，满足用户的滤镜需求。另外，本发明中，将所述视频帧转化为预设格式的目标视频帧，能够保证在添加滤镜效果时，实现无损滤镜处理效果。Specifically, embodiments of the present invention provide a video frame processing method, device and electronic equipment to obtain video frames in a target video that require a filter addition operation, and convert the video frames into target video frames in a preset format. , divide the target video frame into blocks to obtain multiple sub-video frames, dynamically set the gray value of the edge of the sub-video frame to the corresponding target gray value according to the arrangement order of the multiple sub-video frames, and The transparency of the edge of the sub-video frame is the corresponding target transparency. That is, in the present invention, filters are dynamically added to the sub-video frames obtained by splitting a video frame to increase the filter effect, thereby improving video special effects, improving video synthesis quality, and meeting the user's filter needs. In addition, in the present invention, converting the video frames into target video frames in a preset format can ensure that lossless filter processing effects are achieved when adding filter effects.
在上述内容的基础上，本发明的另一实施例提供了一种视频帧处理方法，参照图1，可以包括：Based on the above content, another embodiment of the present invention provides a video frame processing method. Referring to Figure 1, it may include:
S11、获取目标视频中需要进行滤镜添加操作的视频帧，并将所述视频帧转化为预设格式的目标视频帧。S11. Obtain video frames in the target video that require filter addition operations, and convert the video frames into target video frames in a preset format.
其中，预设格式为预设PGM格式。Among them, the default format is the default PGM format.
本实施例中，可以对视频，本实施例中称为目标视频，中的视频帧依次添加滤镜操作。In this embodiment, filter operations can be added sequentially to the video frames in the video, which is called the target video in this embodiment.
针对目标视频中需要进行滤镜添加操作的视频帧，将所述视频帧转化为预设PGM格式的目标视频帧。For video frames in the target video that require a filter addition operation, convert the video frames into target video frames in a preset PGM format.
其中，PGM(存储和交换图像数据的简单文件格式之一)由两部分数据组成,分别是文件头部分和像素数据部分。Among them, PGM (one of the simple file formats for storing and exchanging image data) consists of two parts of data, namely the file header part and the pixel data part.
文件头部分中的第一行是以一个“Magic Number”来标识图片格式，这个magicnumber是P1,P2,P3,P4,P5,P6等模式。其中P1-P3模式的读取使用支持Ascii码格式读取，PIL只支持二进制格式的P4-P6模式的读取。The first line in the file header uses a "Magic Number" to identify the image format. This magic number is P1, P2, P3, P4, P5, P6 and other modes. The reading of P1-P3 mode supports Ascii code format reading, and PIL only supports the reading of P4-P6 mode in binary format.
第二行是图片宽度、图片高度。The second line is the image width and image height.
第三行是这个图片数据的最大值。The third line is the maximum value of this image data.
像素数据是以“row-major order”存放的，按行存放的。默认状况下。每行长度不能超过70个字符，安全的作法是每行存放一个像素。Pixel data is stored in "row-major order", by row. By default. Each line cannot be longer than 70 characters, and it is safe to store one pixel per line.
本实施例中，将视频帧的格式转换为预设PGM格式，是由于现有的jgp，png，bmp，yuv等格式文件只要对其进行处理，必然会有些像素点的值存在有损现象，而PGM文件的每个像素点的值是矢量的，能够达到无损滤镜。滤镜效果采用pgm格式，pgm格式前期就可以可视预览，可见即所得，后期给处理视频设置滤镜效果后又达到无损滤镜处理的效果。In this embodiment, the format of the video frame is converted to the preset PGM format because as long as the existing jgp, png, bmp, yuv and other format files are processed, the values of some pixels will inevitably be lossy. The value of each pixel in the PGM file is vector, which can achieve lossless filters. The filter effect uses the pgm format. The pgm format can be previewed in the early stage. What you see is what you get. After setting the filter effect on the video for processing, the effect of lossless filter processing can be achieved.
需要说明的是，预先可以设置滤镜效果图片，滤镜效果图片的模式可以是上述的P1,P2,P3,P4,P5,P6等模式，本实施例中的预设PGM格式，即为滤镜效果图片的模式，如P2。It should be noted that the filter effect picture can be set in advance. The mode of the filter effect picture can be the above-mentioned P1, P2, P3, P4, P5, P6 and other modes. The preset PGM format in this embodiment is the filter effect picture. Mirror effect picture mode, such as P2.
在将所述视频帧转化为预设格式的目标视频帧之后，还可以确定所述目标视频帧中的像素的灰度值。After converting the video frame into a target video frame in a preset format, the grayscale value of the pixels in the target video frame may also be determined.
在实际应用中，针对目标视频帧中的每一像素，确定其对应的灰度值。In practical applications, for each pixel in the target video frame, its corresponding gray value is determined.
具体的，确定所述目标视频帧中的像素的灰度值，可以包括：Specifically, determining the grayscale value of the pixel in the target video frame may include:
1)提取所述目标视频帧中的像素的预设通道的通道值，并对所述通道值进行修正操作，得到修正后的通道值。1) Extract the channel value of the preset channel of the pixel in the target video frame, and perform a correction operation on the channel value to obtain the corrected channel value.
具体的，针对目标视频帧中的像素，可以提取其预设通道的通道值。其中，预设通道可以是R、G、B通道。可以获取像素的RGBA通道图，然后从中提取出R、G、B值。然后对所述通道值进行修正操作，得到修正后的通道值。Specifically, for the pixels in the target video frame, the channel value of its preset channel can be extracted. Among them, the preset channels can be R, G, and B channels. You can obtain the RGBA channel map of the pixel and then extract the R, G, and B values from it. Then, a correction operation is performed on the channel value to obtain the corrected channel value.
其中，修正后的通道值为：Among them, the corrected channel value is:
Rlinear＝pow(R,1/Gamma)Rlinear=pow(R,1/Gamma)
Glinear＝pow(G,1/Gamma)Glinear＝pow(G,1/Gamma)
Blinear＝pow(B,1/Gamma)；Blinear=pow(B,1/Gamma);
其中，Rlinear，Glinear，Blinear在[0,1]范围，Rlinear为修正后的R值，Glinear为修正后的G值，Blinear为修正后的B值。Gamma为固定值，如为2.2。Among them, Rlinear, Glinear, and Blinear are in the range of [0,1], Rlinear is the corrected R value, Glinear is the corrected G value, and Blinear is the corrected B value. Gamma is a fixed value, such as 2.2.
2)根据修正后的通道值，计算所述像素的线性校正值。2) Calculate the linear correction value of the pixel based on the corrected channel value.
具体的，像素的线性校正值Clinear为：Specifically, the linear correction value Clinear of the pixel is:
Clinear＝0.2126Rlinear+0.7152Glinear+0.0722Blinear。Clinear=0.2126Rlinear+0.7152Glinear+0.0722Blinear.
3)确定所述线性校正值对应的灰度值，并作为所述像素的灰度值。3) Determine the gray value corresponding to the linear correction value and use it as the gray value of the pixel.
具体的，根据线性变换计算得到的上述线性校正值，根据线性Gamma校正公式进行校正，得到线性校正值对应的灰度值Csrgb，具体为：Specifically, the above linear correction value calculated according to the linear transformation is corrected according to the linear Gamma correction formula to obtain the grayscale value Csrgb corresponding to the linear correction value, specifically as follows:
Csrgb＝12.92*Clinear，当Clinear<＝0.0031308；Csrgb=12.92*Clinear, when Clinear<=0.0031308;
Csrgb＝1.055*Clinear1/2.4-0.055，当Clinear>0.0031308Csrgb＝1.055*Clinear1/2.4 -0.055, when Clinear>0.0031308
通过本步骤，即可得到每个像素点对应的像素值等于PGM输入的灰度图像灰度值。Through this step, it can be obtained that the pixel value corresponding to each pixel point is equal to the grayscale value of the grayscale image input by PGM.
本实施例中，确定所述线性校正值对应的灰度值，即为对图像进行灰度化处理。In this embodiment, determining the grayscale value corresponding to the linear correction value is to perform grayscale processing on the image.
需要说明的是，在执行确定所述目标视频帧中的像素的灰度值之后(具体为确定所述线性校正值对应的灰度值，并作为所述像素的灰度值之后)，执行步骤S12之前，还可以对所述目标视频帧进行滤波操作。It should be noted that, after determining the grayscale value of the pixel in the target video frame (specifically, determining the grayscale value corresponding to the linear correction value and using it as the grayscale value of the pixel), perform the step Before S12, a filtering operation may also be performed on the target video frame.
在进行滤波时，可以采用高斯滤波，通过滤波，能够避免干扰。When filtering, Gaussian filtering can be used. Through filtering, interference can be avoided.
S12、对所述目标视频帧进行分块，得到多个子视频帧。S12. Divide the target video frame into blocks to obtain multiple sub-video frames.
具体地，将所述目标视频帧拆分为边长为预设长度的多个矩形图片，并将每一矩形图片作为一子视频帧，并基于所述预设长度，设置所述子视频帧边长的像素值。Specifically, the target video frame is split into multiple rectangular pictures with a side length of a preset length, each rectangular picture is treated as a sub-video frame, and based on the preset length, the sub-video frame is set The pixel value of the side length.
如，把为灰度图像的目标视频帧读取到像素阵列中，进行分块，将PGM全图分成变成边长为m(预设长度)的正方形，按列顺序生成子图，每一子图即为一子视频帧。For example, read the target video frame that is a grayscale image into a pixel array, divide it into blocks, divide the entire PGM image into squares with a side length of m (preset length), and generate sub-images in column order. Each A sub-picture is a sub-video frame.
子视频帧边长对应的区域像素p＝m/原图分辨率大小。The area pixel corresponding to the side length of the sub-video frame is p=m/original image resolution size.
行和列方向上子视频帧的个数＝原图分辨率大小/子图边长对应的像素(p)。The number of sub-video frames in the row and column directions = original image resolution size/pixels (p) corresponding to the side length of the sub-image.
子图块序号按照1、2、3、4……排列。The sub-tile serial numbers are arranged according to 1, 2, 3, 4...
S13、按照所述多个子视频帧的排列顺序，动态设置所述子视频帧的边缘的灰度值为对应的目标灰度值，以及所述子视频帧的边缘的透明度为对应的目标透明度。S13. According to the arrangement order of the multiple sub-video frames, dynamically set the gray value of the edge of the sub-video frame to the corresponding target gray value, and the transparency of the edge of the sub-video frame to the corresponding target transparency.
在实际应用中，动态设置子视频帧的边缘的灰度值和透明度时，需要确定子视频帧的边缘的目标灰度值以及目标透明度，再进行动态滤镜添加操作。In practical applications, when dynamically setting the grayscale value and transparency of the edge of a sub-video frame, it is necessary to determine the target grayscale value and target transparency of the edge of the sub-video frame, and then add a dynamic filter.
即步骤S13包括：That is, step S13 includes:
1)确定所述子视频帧的边缘的目标灰度值以及目标透明度；1) Determine the target grayscale value and target transparency of the edge of the sub-video frame;
2)按照所述多个子视频帧的排列顺序，在不同的滤镜添加时间内，将所述滤镜添加时间对应的所述子视频帧的边缘的灰度值设置为所述目标灰度值，以及将所述子视频帧的边缘的透明度设置为所述目标透明度。2) According to the arrangement order of the plurality of sub-video frames, during different filter addition times, set the grayscale value of the edge of the sub-video frame corresponding to the filter addition time to the target grayscale value , and set the transparency of the edge of the sub-video frame to the target transparency.
其中，确定所述子视频帧的边缘的目标灰度值以及目标透明度的实现过程如下：The implementation process of determining the target grayscale value and target transparency of the edge of the sub-video frame is as follows:
本实施例中，在添加滤镜时，会对子视频帧的边缘的灰度值以及透明度进行调整，但是子视频帧的非边缘区域的灰度值和透明度值保持不变。In this embodiment, when adding a filter, the grayscale value and transparency of the edge of the sub-video frame are adjusted, but the grayscale value and transparency value of the non-edge area of the sub-video frame remain unchanged.
参照图2，确定所述子视频帧的边缘的目标灰度值以及目标透明度可以包括：Referring to Figure 2, determining the target gray value and target transparency of the edge of the sub-video frame may include:

本实施例中，不对整个目标视频帧统一进行滤镜添加操作，而是针对目标视频帧中的子视频帧，在不同的滤镜添加时间内，可以对不同的子视频帧进行滤镜添加操作。In this embodiment, the filter addition operation is not performed uniformly for the entire target video frame, but for the sub-video frames in the target video frame, the filter addition operation can be performed on different sub-video frames during different filter addition times. .
本实施例中，参照图3，“按照所述多个子视频帧的排列顺序，在不同的滤镜添加时间内，将所述滤镜添加时间对应的所述子视频帧的边缘的灰度值设置为所述目标灰度值，以及将所述子视频帧的边缘的透明度设置为所述目标透明度”具体包括：In this embodiment, referring to Figure 3, "According to the arrangement order of the multiple sub-video frames, at different filter adding times, the gray value of the edge of the sub-video frame corresponding to the filter adding time is "Set to the target grayscale value, and set the transparency of the edge of the sub-video frame to the target transparency" specifically includes:

S32、按照所述多个子视频帧的排列顺序，确定每一滤镜添加时间对应的子视频帧。S32. Determine the sub-video frame corresponding to each filter addition time according to the arrangement order of the multiple sub-video frames.

For example, within 1/30s, a filter operation can be performed on the first sub-video frame, and within 2/30s, a filter operation can be performed on the second and third sub-video frames. Three sub-video frames are filtered simultaneously... When performing filter operations on the second and third sub-video frames at the same time, parallel filter addition operations can be used to increase processing speed and reduce time consumption.

即通过PGM像素值的变化改变视频帧图片颜色的梯度变化，进而达到视频‘轨迹’滤镜的效果。若是，更改上述的预设PGM格式，最终展示的滤镜效果也不一样。That is, the gradient change of the color of the video frame picture is changed through the change of PGM pixel value, thereby achieving the effect of the video 'track' filter. If so, if you change the default PGM format mentioned above, the final filter effect displayed will also be different.
在对本视频帧进行滤镜添加之后，可以对下一视频帧进行滤镜添加，以此类推，直至最后一个视频帧。After adding filters to this video frame, you can add filters to the next video frame, and so on, until the last video frame.
