Recognition method of kicking and stride movements of Taekwondo athletes based on Gaussian mixture model
Abstrct
In order to improve the accuracy of Taekwondo Athletes' motion recognition, a human motion recognition method based on Gaussian mixture model is proposed. This paper decomposes the structure of kicking and stride movement of human Taekwondo athletes to form a group of recognition targets, and investigates the changes of muscle surface under kicking and stride movement of Taekwondo athletes. The Gaussian mixture model is used to collect the shorttime feature images of kicking and stride movement of Taekwondo athletes, and the wavelet time-domain features of the images are obtained as the recognition vector space, The experimental results show that the method can effectively identify the movement characteristics and muscle changes of Taekwondo athletes, fully meet the research requirements.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
