[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0027] In the field of video editing, users often need to split and crop videos. One common scenario is to split a complete video into multiple small segments based on the degree of change in the current video shots. The shots in each segment after segmentation are relatively stable, thus achieving the purpose of video segmentation and cropping.
[0028] In the existing technology, the common method for video segmentation is to search for frames with shot changes in the entire video during the editing process. This method is labor-intensive and subjective, and also has technical problems such as low efficiency and low accuracy.
[0029] To address this time-consuming and labor-intensive manual process, the inventors devised a technical solution: a color-data-driven intelligent scene shot segmentation solution. This solution analyzes and decodes the color data corresponding to each video frame, automatically detecting soft and hard cuts in the video. Specifically, in actual situations, the color data of the video frame corresponding to a segmentation point differs significantly from the color data of the previous frame.
[0030] Compared to traditional manual screening, this solution offers greater accuracy and efficiency. This not only significantly reduces the workload of manual screening but also improves the efficiency and quality of video editing. Furthermore, compared to typical video processing, only color data needs to be determined, meaning analysis is performed using partially decoded data rather than fully decoded video, resulting in faster performance.
[0031] Figure 1 A thread diagram of a video processing method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the flowchart includes: a decoding thread and an inference thread.
[0032] In the decoding thread, the video is decoded to obtain the red-green-blue (RGB) data corresponding to each video frame. The RGB data corresponding to all video frames are then downsampled and cached. When the video is segmented, the inference thread is started, the RGB data in the data cache is input into the segmentation model, and all segmentation points in the video are output. The video is then segmented based on each segmentation point.
[0033] The segmentation process may include calling back the segmentation point to the upper layer, and having the upper layer perform segmentation. The downsampling process may include using a graphics processing unit (GPU) to implement the downsampling process.
[0034] It should be understood that the color data may be RGB data or Luminance-Chrominance (YUV) data. The embodiments of the present disclosure are described using RGB data, and the implementation principle of YUV data is similar.
[0035] The video processing method according to the embodiments of the present disclosure is executed by an electronic device, which may be a mobile phone, a computer, a tablet, a server, and the like.
[0036] The following is a specific implementation process of the video processing method, device, and electronic device involved in the embodiments of the present disclosure. Some examples are only for illustrative purposes and are not limiting.
[0037] Figure 2 Schematic diagram of the video processing method provided in the embodiment of the present disclosure Figure 1 .like Figure 2 As shown, the video processing method includes:
[0038] Step 21: determining color data corresponding to video frames in the video to be segmented according to the video to be segmented;
[0039] In this step, after obtaining the video to be segmented, the color data in the video frames of the video to be segmented are extracted to obtain the color data corresponding to the video frames in the video to be segmented.
[0040] The video to be segmented may be obtained by: obtaining it from an image acquisition device (eg, a camera), obtaining it from a preset physical space (eg, a computer, a USB flash drive), or downloading it from a network terminal, etc.
[0041] Optionally, step 21 may include the following implementation steps:
[0042] Step 1: Perform frame processing on the video to be segmented to obtain the video frames of the video to be segmented;
[0043] In this implementation, the video to be segmented is converted into frame images, which can be achieved using video processing software or programming libraries. The general steps include opening the video file, reading each video frame and decoding it into image data, and then saving each image as a frame (i.e., video frame).
[0044] Step 2: Extract the color data of the video frame to be segmented.
[0045] In this implementation, after decoding the video frame, the RGB channel information is extracted. Typically, the RGB data of each pixel is stored in a certain format (such as 24-bit representation) in the frame image. By reading the corresponding color channel value of each pixel, the complete RGB data of the video frame can be obtained.
[0046] It should be understood that the embodiments of the present disclosure do not limit the number of video frames obtained by decoding.
[0047] Step 22: Obtain the segmentation position corresponding to the video to be segmented according to the color data corresponding to the video frame in the video to be segmented;
[0048] The variation of color data corresponding to adjacent video frames at the segmentation position is greater than a preset threshold.
[0049] That is, when the amount of change in the color data corresponding to two adjacent video frames is large, it is considered that a shot cut occurs between the two adjacent video frames.
[0050] In this step, the color data corresponding to each video frame in the video to be segmented obtained above is processed to obtain segmentation positions for segmenting the video to be segmented.
[0051] In this implementation, the RGB data corresponding to two adjacent video frames can describe whether the camera has rotated. This is because when the camera rotates, the scene captured by the image acquisition device (e.g., a camera) changes, resulting in different image content in consecutive frames. For example, when the camera rotates, the position of objects in adjacent frames may shift, and the color distribution may also change.
[0052] By comparing the RGB data between the two frames, these changes can be detected to determine whether the camera has rotated. In other words, the trained segmentation model can detect such changes based on the RGB data to obtain the segmentation position corresponding to the video to be segmented.
[0053] Optionally, one implementation of step 22 may be: inputting color data corresponding to video frames in the video to be segmented into a pre-trained segmentation model to obtain segmentation positions corresponding to the video to be segmented;
[0054] The segmentation model is trained based on the color data and the segmentation positions corresponding to the color data.
[0055] In a possible implementation, after obtaining the color data in the video to be segmented, it is directly input into the segmentation model, and the segmentation position of the video to be segmented can be output.
[0056] Step 23: Segment the video to be segmented according to the segmentation position to obtain at least two video segments.
[0057] The video frames at the start and end positions of the two adjacent video segments are adjacent in the video to be segmented, that is, the end video frame of the first video segment and the beginning video frame of the second video segment of the two adjacent video segments are two consecutive frames in the video to be segmented.
[0058] In this step, the video to be segmented is divided into several video segments based on the segmentation positions.
[0059] Optionally, when the segmentation position is at least one segmentation point, each segmentation point corresponds to the first video frame in the video to be segmented.
[0060] Then, step 23 may be: dividing the video to be divided into at least two video segments according to at least one segmentation point.
[0061] In a possible implementation, the video to be segmented can be divided into 100 video frames. At this time, the segmentation model outputs three segmentation points, namely: the 16th video frame, the 50th video frame, and the 70th video frame. Then the video to be segmented can be divided into 4 video segments, namely the video segments corresponding to the 1st to 15th frames, the video segments corresponding to the 16th to 49th frames, the video segments corresponding to the 50th to 69th frames, and the video segments corresponding to the 70th to 100th frames.
[0062] The video processing method provided in this embodiment determines the color data corresponding to the video frames in the video to be segmented, and then determines the segmentation position corresponding to the video to be segmented based on the color data corresponding to the video frames in the video to be segmented. The video to be segmented is then segmented based on the segmentation position and the amount of change in the color data corresponding to adjacent video frames at the segmentation position is greater than a preset threshold, resulting in at least two video segments. The video frames at the start and end positions of the two adjacent video segments are adjacent in the video to be segmented. In this technical solution, when the camera changes, the color data between the two frames of the image differs significantly. That is, the change in the color data of the video frames can be used to determine the video frame corresponding to the segmentation point, thereby reducing the workload of manual screening and improving segmentation efficiency and accuracy.
[0063] Based on the above embodiments, Figure 3 Schematic diagram of the video processing method provided in the embodiment of the present disclosure Figure 2 .like Figure 3 As shown, the video processing method further includes:
[0064] Step 31: Obtain multiple sets of color data and the segmentation position corresponding to each set of color data;
[0065] In this step, multiple groups of color data and the segmentation positions corresponding to each group of color data can be obtained from some previous experiments and / or some data actually collected and stored in the physical space.
[0066] In a possible implementation, taking a set of color data as an example, it may include: 50 color data, wherein the 5th color data and the 36th color data are marked as the color data of the corresponding points in the segmentation position.
[0067] Step 32: According to the multiple sets of color data and the segmentation positions corresponding to each set of color data, a preset network model is trained to obtain a segmentation model.
[0068] In this step, the preset network model is trained using the multiple sets of color data obtained above and the segmentation positions corresponding to each set of color data, and the parameters in the network model are continuously adjusted until the loss function of the network model tends to converge, that is, the training results are close to or consistent with the actual segmentation positions.
[0069] For example, the network model can be any of the following (the following are examples):
[0070] BP neural network: BP neural network is a neural network learning algorithm. It is a hierarchical neural network composed of an input layer, an intermediate layer, and an output layer. The intermediate layer can be expanded to multiple layers. In order to reduce the error between the desired output and the actual output, the connection weights are corrected layer by layer from the output layer through each intermediate layer and back to the input layer. This process is repeated until the global error of the network tends to a given minimum value, that is, the learning process is completed.
[0071] Radial Basis Function Neural Network: RBF (Radial Basis Function, RBF) neural network is a neural network proposed in the late 1980s. It is a three-layer feedforward network with a single hidden layer.
[0072] Perceptron neural network: A perceptron neural network is a neural network with a single layer of computational neurons, and the transfer function of the network is a linear threshold unit;
[0073] Linear neural network: A linear neural network is a relatively simple neural network consisting of one or more linear neurons. It uses a linear function as the transfer function, so the output can be any value.
[0074] Convolutional Neural Networks (CNN): In convolutional neural networks, the convolution kernel is a very important part of the convolutional neural network. Each convolution kernel can learn a feature of the image, and finally a feature map is obtained by full connection.
[0075] Therefore, in this embodiment, the CNN model can be preferably used as a training model for the segmentation model.
[0076] The disclosed embodiments provide a video processing method that obtains multiple sets of color data and the segmentation positions corresponding to each set of color data. This method then trains a pre-set network model based on the multiple sets of color data and the corresponding segmentation positions, thereby generating a segmentation model. This technical solution trains the segmentation model based on the multiple sets of color data and the corresponding segmentation positions, providing an accurate basis for outputting the corresponding segmentation positions when a motion vector is subsequently input.
[0077] Based on the above embodiments, Figure 4 Schematic diagram of the video processing method provided in the embodiment of the present disclosure Figure 3 .like Figure 4 As shown, after step 21, the video processing method further includes:
[0078] Step 41: downsample the color data corresponding to the video frames in the video to be segmented to obtain downsampled color data;
[0079] In this step, since the color data corresponding to the video frames obtained above has a large amount of data or contains some unstable information that may affect the accuracy, the color data corresponding to all video frames may be downsampled.
[0080] Optionally, a GPU is used to implement downsampling processing of color data corresponding to all video frames.
[0081] As a possible implementation, the RGB data of all video frames can be loaded into the GPU memory, and the RGB data of each video frame can be downsampled using a GPU-accelerated image processing algorithm. This can be done by using pixel mean, maximum, or other filters to reduce the resolution of the image. The downsampled RGB data is then saved to the GPU memory or main memory for subsequent processing or output.
[0082] Step 42: Input the downsampled color data into the segmentation model to obtain the segmentation position corresponding to the video to be segmented.
[0083] In this step, the obtained color data after downsampling is input into the segmentation model, so that the segmentation model outputs the segmentation position corresponding to the video to be segmented, which can be at least one segmentation point determined in the above embodiment.
[0084] The disclosed embodiments provide a video processing method that downsamples the color data corresponding to video frames in a video to be segmented, obtaining the downsampled color data. This downsampled color data is then input into a segmentation model to obtain the segmentation positions corresponding to the video to be segmented. This technical solution reduces the density of the color data by downsampling the color data corresponding to the video frames, thereby reducing the amount of data, lowering computational complexity, and increasing the speed of obtaining the segmentation positions while ensuring the accuracy of the segmentation positions.
