Improving the Quality of Left-Behind Children’s Participation in Sports through Wireless Network Monitoring

Abstract

Urbanization is the process that people shift from rural to urban areas, which has led to large numbers of left-behind children in China. The left-behind children stay in rural regions of China while their parents work in urban areas. The left-behind children have few opportunities to participate in sports due to the lacking of concern, and it is not of high quality even though they participate in sports. Therefore, it is necessary to improve the quality of left-behind children's sports participation through wireless network monitoring. Wireless network monitoring transmits high-definition (HD) video streaming in real time to facilitate feedback timely. This paper studies the two-dimensional (2D) integer discrete cosine transform (DCT) and analyzes the reason for image distortion, then an improved DCT coefficient quantization approach is proposed for long-distance real-time transmission of HD video streaming, and a noise processing with a zero-mean noise processing is added in optimized approach to solve the image distortion problem. The experimental results show that the proposed improved approach has a good performance in reducing the blocking artifacts, and within the image reconstruction, the proposed approach improves the subjective video quality.

“…Intelligent video analysis technology, with the help of computer data processing functions, effective identification, and analysis and judgment of the target event, can make timely and appropriate responses to abnormal behavior and insecurity events and achieve preset early warning and analysis, feature storage, and other functions 7 . Zhao improved the quality of sports participation of left‐behind children by transmitting high‐definition video streams in real time through wireless network monitoring 8 . The method is based on the location service provider's access to the video of the examination room.…”

“…7 Zhao improved the quality of sports participation of left-behind children by transmitting high-definition video streams in real time through wireless network monitoring. 8 The method is based on the location service provider's access to the video of the examination room. Location service monitoring is based on the location service provider obtaining the geographic location of the monitoring target and providing personalized location services for the target through the analysis of the target location.…”
