Problems solved by technology
[0002] The information in the image or video is the most direct and accessible to human beings. In terms of video surveillance, its camera speed and storage capacity are very limited. In order to improve the resolution of the image and make it close to the target prototype, people Using the method of improving hardware to increase the resolution of its image is costly, technically difficult, and is easily affected by various factors, and its improvement is limited. In order to play high-quality video of streaming media, a very narrow width is used. , through frame reconstruction technology, to compress and transmit the data in the video, in order to achieve the best image quality technology with the least data, people use software to improve the resolution of the image, considering the amount of calculation and reconstruction Quality, using image processing technology, in the process of improving video quality, video frame reconstruction is a very critical process, which affects the level of video quality

Embodiment
[0020] Example: refer to figure 1 , a video frame reconstruction method, comprising the following steps:
[0021] S1. Input the original video A1, and reconstruct the original video A1 into a higher-resolution processed video A2 through the maximum a posteriori probability estimation method;
[0022] S2. Elimination of noise in the processing video A2: establish a robust adaptive background model in a complex environment, and segment the image in the processing video A2, and use the feature extraction method of Hog feature and contour feature fusion to process the image in the video A2 Effective features are extracted, and the extracted effective features are used for multi-frame image reconstruction method to obtain the processed video A3 after noise removal;
[0023] S3. Detection and segmentation of short video boundaries: use the histogram method to calculate the difference between two adjacent frames. The formula of the histogram method is: D k,k+1 =∑|H k (i)-H k+1 (i...
