Abstract
With the development of computer technology and management science, decision support systems have emerged that can improve the quality and effects of decision-making. This study mainly examined the application of the wireless communication of an embedded microprocessor and computer vision in the decision support system of martial arts competition referees. Using the embedded microprocessor’s characteristics of a small size, high precision, high reliability, and high efficiency, a decision support system for martial arts competition referees was designed. In the experiment, the similarity between the target field and the source field could be controlled by adjusting the mean value. To better extract the target, this study used the time domain changes of the three adjacent frames, before, middle, and back, to detect the moving target to extract the change detection template. The Canny edge detection method was used to extract the edge information of the image and eliminate the nonmotion area; then, morphology was used to correct the image to complete the connection of the broken edge to obtain the final initial segmentation mask image. In the process of calculation, there were some noises and small fragments. In this study, morphology and background difference were used to optimize the segmented image. Experimental data show that the algorithm detection accuracy rate was high—between 70% and 100%—and the effect was relatively ideal. The results indicate that the proposed algorithm can effectively reduce matching noise, improve the matching accuracy of the edge area and the low-texture area, and achieve a fast matching speed.
Highlights
After a long process, human understanding of vision has changed from perceptual knowledge to qualitative and quantitative analysis
The support vector machine prediction program was implemented by VC6.0 and MATLAB 6.5 programming, and it was run on a computer with a clock speed of 1.92 GHz and a memory of 256 model library (MB) [19]
The reliability of the matching algorithm based on region similarity was affected by the size of the selected support window
Summary
Human understanding of vision has changed from perceptual knowledge to qualitative and quantitative analysis. In present-day China, the most effective means of protection is to carry out the official traditional martial arts competition every year. The competition encourages the development of traditional martial arts, including statistical analyses on the participants and scale of the traditional martial arts competition in Beijing in recent years, which gives traditional martial arts a base to recuperate. The research goal of computer vision is to use cameras or other sensors and computers instead of the human eyes and brains to process one or more images, to establish an artificial intelligent vision system that can automatically obtain external information from images or multidimensional data. Competitive martial arts is a pioneer in the world of sports. According to the requirements of decision-making, this study integrated and summarized the data of different formats in a traditional database, which provides a unified comprehensive data
