Real-time camera motion tracking in planar view scenarios
We propose a novel method for real-time camera motion tracking in planar view scenarios. This method relies on the geometry of a tripod, an initial estimation of camera pose for the first video frame and a primitive tracking procedure. This process uses lines and circles as primitives, which are extracted applying classification and regression tree. We have applied the proposed method to high-definition videos of soccer matches. Experimental results prove that our proposal can be applied to processing high-definition video in real time. We validate the procedure by inserting virtual content in the video sequence
Knowledge, attitudes, and practices related to COVIDâ19 infection, related behavior, antibiotics usage, and resistance among Syrian population: A crossâsectional study
Abstract Background and Aims Antibiotic resistance is seen as a worldwide health risk as a result of the overuse of antibiotics. Many countries noted that antibiotic usage was high during the COVIDâ19 pandemic. The purpose of this study is to evaluate Syrians' knowledge, attitudes, and practice about the use of antibiotics and antibiotic resistance during the COVIDâ19 epidemic. Methods A crossâsectional study was conducted using an online questionnaire to collect the data from the Syrian population from February 5 to March 4, 2022. Syrians 18âyears or older all over the world were able to participate in this study. A convenience snowball sampling method was used. SPSS version 20.0 was used to analyze the data. To examine the results, binominal logistic regression was used. Statistical significance was defined as a pâ<â0.05. Results Out of 2406 respondents, 60.2% knew that transmission of COVIDâ19 could occur even if the patient has not developed any symptoms, and 91.6% were able to recognize the main clinical symptoms of COVIDâ19. There was a statistically significant difference between male and female knowledge of COVIDâ19 (pâ=â0.002), with males having 3.78â±â2.1 (2.7â3.87) and females scoring 3.93â±â2.3 (3.7â4.1). Newly graduated students have more knowledge of COVIDâ19 than other subtypes of Job (pâ=â0.0001), and those with medical practice are more knowledgeable than those without (pâ=â0.0001). Only 16.6% answered that taking antibiotics would not speed up the recovery from all the infections. 65.3% answered correctly that misuse of antibiotics could cause antibiotic resistance. Conclusion Our study concluded that the Syrian population demonstrated good knowledge of COVIDâ19 and moderate acceptance of the new norm. Knowledge regarding antibiotic use and resistance and practice of preventive measures was poor, which can encourage the health authorities to develop community education programs to increase public awareness of the usage of antibiotics and safety protocols during the COVIDâ19 pandemic
