Background Difference

In order to improve the video image processing technology, this paper presents a moving object detection and tracking algorithm based on computer vision technology. Firstly, the detection performance of the interframe difference method and the background difference model method is compared comprehensively from both theoretical and experimental aspects, and then the Robert edge detection operator is selected to carry out edge detection of the vehicle. The research results show that the algorithm proposed in this paper has the longest running time per frame when tracking a moving target, which is about 2.3 times that of the single frame running time of the CamShift algorithm. The algorithm has high running efficiency and can meet the requirements of real-time tracking of a foreground target. The algorithm has the highest tracking accuracy, the time consumption is reduced, and the error of the tracking frame deviating from the real position of the target is the least.

Video surveillance system with image recognition and image tracking capabilities has a wide range of applications in the field of city protection, social security and public safety. In this paper, based on the analysis of image detection and tracking principles, image recognition and tracking algorithm based PID fuzzy control is proposed. First, the image on the basis of the gray-scale image is acquired by the video processor and the linearization processing, and then through the expansion operation of mathematical morphology the candidate region of the image recognition is taken, and then the final image region is obtained through the vertical positioning and horizontal positioning of the region Finally, through the PID control algorithm it is the image of the track. Simulation results show that the PID fuzzy control-based image recognition and tracking algorithm possesses good vehicle license plate image recognition and tracking performance and good practicability.

Objective: To assess postoperative clinical functional outcomes, based on the American Orthopaedic Foot & Ankle Society (AOFAS) score, of tendoscopies performed in the treatment of foot and ankle pathologies. Methods: Our comparative assessment used AOFAS scores obtained preoperatively and at early and late postoperative stages - 1 month and 6 to 12 months after surgery - of 14 patients with foot and ankle tendinopathies. These included peroneal tendon dislocation, peroneal tendonitis, and tearing of the peroneus longus or brevis, all treated with tendoscopy for peroneal reconstruction and tenorrhaphy. The AOFAS score was obtained by functional assessment during outpatient physical examination. We presented a descriptive analysis of cases, comparing scores over time through the Friedman test followed by Dunn’s test. The relationship between score variations and sex was assessed using the Mann-Whitney test; their comparison with age used Spearman’s linear correlation coefficient. Significance levels were 5%.Results: The AOFAS score showed important improvements such as preoperative scores of 56 and 67 followed by postoperative scores of 100 both in the early and late stages, supporting the efficacy and persistence of this treatment strategy. The p-value obtained after statistical analysis was <0.0001. Conclusion: We concluded that the treatment of foot and ankle comorbidities with tendoscopy, in addition to being less invasive, shows consistency and efficacy as demonstrated by the AOFAS score and functional assessment via postoperative physical examinations. AOFAS scores were increased and maintained at high levels in the postoperative period, demonstrating the efficacy of this procedure and the duration of treatment results.

ABSTRACT Introduction Human motor dysfunction can affect the quality of life, especially waist dysfunction. And an effective means to improve muscle strength during exercise. Object This article compares and analyzes the effectiveness of human muscle exercise on the decline in quality of life caused by motor dysfunction. Method The article divides patients with motor dysfunction into trunk isokinetic training group (experimental group) and waist and abdominal muscle functional training group (control group), and comparative analysis of related indicators before and after treatment. Results Before treatment, the specific indicators of the two were different (P>0.05). After treatment, the patients’ quality of life indicators and motor function indicators were significantly different (P<0.05). Conclusion Exercise has an obvious curative effect for patients with human motor dysfunction, and it is worthy of clinical promotion.
