Evaluation of Ice Skaters' Technical Skills

Evaluation of ice skaters’ technical skills Minkyu Kim [email protected] Motivation During a skater’s performance in an ice link, due to his or her fast and intricate movements, audiences hardly recognize how well the player’s performance is done from the perspective of technical skills. If a program can count the number of spins he or she does or detect the position and angle of foot before and after jump, which is important to judge the quality of jumps and finally give us a score for the technical skills, it will be very useful. Goal In this study, a skater’s motion is recognized through image processing in MATLAB to evaluate her technical skills. For example, to judge how well a play is done, the number of spinning a skater does is counted and the angles and relative positions of her feet when she jumps from and lands on the ground are tracked and quantified in MATLAB where a database for the judging criteria is saved beforehand. Therefore, before referees’ announcement for the final score the skater gets, we are able to calculate the score. Design A skater’s performance is recorded as a wmv file and saved in MATLAB. The skater’s motion is then read frame by frame in MATLAB. By using intensity threshold and edge detection combined with image processing techniques such as Particle Swarm Optimization (PSO), mean shift model, and so on [1-3], only her motion is highlighted frame by frame and anything else becomes dark or vice versa. By observing and analyzing each frame, the number of spinning or other technical movements is recognized. According to judging criteria referring from “2013-14 Adult Singles Free Skate Requirements [4],” her performance is evaluated and final score is shown as a result. I will not use an Android device.

Brannen An earring's journey When we talked to Starr Andrews after the juvenile ladies event, we noticed a pretty earring in her left ear, a small gold hoop with a crystal heart dangling from it. We didn't realize we had seen it before: Kristi Yamaguchi wore it as she won her Olympic gold medal in Albertville. It turns out that Tai Babilonia gave the earring to Yamaguchi back in 1992, and she wore it for the entire Olympic competition and for years afterward. "I really wanted to give her something special, something really cool," Babilonia told us. "And I saw her wearing it on the cover of Sports Illustrated." http://web.icenetwork.com/news/2014/01/23/67027190 1/5 6/29/2018 The Inside Edge: Sisterhood of the traveling earring | icenetwork.com: Your home for figure skating and speed skating. "I got it from Tai during a trying time when I competed," Yamaguchi said. "I wore it for good luck, and it symbolized strength and hope for me." Yamaguchi eventually gave the earring to Katia Gordeeva after the death of Gordeeva's husband, Sergei Grinkov, and eventually Gordeeva gave it back to Babilonia.

Gutsy Performance in Sochi
Recitation E Gutsy Performance in Sochi One of Japan’s most popular athletes should have known she couldn’t leave quietly. Mao Asada’s press conference Wednesday to officially announce her retirement from figure skating attracted some 350 journalists and was telecast live across Japan. Asada had led the country’s figure skating scene since her teens with her trademark triple axel. She started skating at the age of five and won world championships in 2008, 2010 and 2014 . Her illustrious career also included a silver medal at the 2010 Vancouver Olympics. Asada, who announced her retirement from her 21-year career on her blog two days ago, occupied a special place in the Japanese sports landscape. Her popularity far exceeded that of other figure skaters, even those with more gold medals. At Wednesday’s press conference, Asada called her performance in the free skating event at the 2014 Sochi Olympics her most memorable. “It’s difficult to pick just one,” Asada said. “But the free skating in Sochi definitely stands out.” She placed 16th in the short program in Sochi after falling on her triple Axel, under-rotating a triple flip, and doubling a triple loop. But in a stirring free skate Asada rebounded, earning a personal best score of 142.71. This made her the third woman to score above the 140 mark after Yuna Kim’s 2010 Olympics score and Yulia Lipnitskaya’s 2014 Olympics team event score. It placed Asada third in the free skating and sixth overall. Even though she didn’t win a medal, it was a performance that many will never forget.

SCRIPT: the Undisputed Queen of Figure Skating Yuna Kim Became A
SCRIPT: The undisputed queen of figure skating Yuna Kim became a Lillehammer 2016 Winter Youth Olympic Games Ambassador and spoke of the Olympic values during a skating work shop with the Norwegian national team and local youngsters in the YOG host city. Better know as ‘Queen Yuna’ the South Korean legend of figure skating also previewed the first Grand Prix event of the coming season Skate America in Milwaukee, USA this October where her fellow South Korean athlete and a medalist of Innsbruck 2012 Winter Youth Olympic Games, Park So-youn, the National Champion, will be going for gold against Russia’s Yuila Lipnitskaya and Evgenia Medvedeva. Yuna Kim retired from figure skating having never finished a major ladies singles event off the podium, a remarkable achievement that most notably saw her claim Olympic gold at the Olympic Winter Games Vancouver 2010 and a silver medal at the Olympic Winter Games Sochi 2014. The Sochi gold medal was awarded to Russia’s Adelina Sotnikova, a graduate of the first Winter Youth Olympic Games in Innsbruck in 2012. One thousand, one hundred athletes aged 15 to 18 from 70 nations will compete in 70 medal events. The seven sports on the Olympic program will feature plus a few new additions, including team ski-snowboard cross and monobob. The Winter YOG will take place in existing venues from the legacy of the Lillehammer 1994 Olympic Winter Games. The IOC chooses Ambassadors for each edition of the Youth Olympic Games. Sporting legends such as Usain Bolt, Michael Phelps, Yao Ming and Yelena Isinbayeva have supported the YOG.

The Effect of School Closure On
Teasing Out the Compressed Education Debates in Contemporary South Korea: Media Portrayal of Figure Skater Yuna Kim by Hye Jin Kim B.A., Simon Fraser University, 2010 Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts in the Department of Sociology and Anthropology Faculty of Arts and Social Sciences Hye Jin Kim 2013 SIMON FRASER UNIVERSITY Summer 2013 Approval Name: Hye Jin Kim Degree: Master of Arts (Sociology) Title of Thesis: Teasing Out the Compressed Education Debates in Contemporary South Korea: Media Portrayal of Figure Skater Yuna Kim Examining Committee: Chair: Dr. Barbara Mitchelle Professor Dr. Cindy Patton Senior Supervisor Professor Dr. Jie Yang Committee member Assistant Professor Dr. Helen Leung External Examiner Associate Professor Gender, Sexuality, and Women’s Studies Date Defended/Approved: July 30, 2013 ii Partial Copyright Licence iii Abstract In this thesis, I argue that the heated debates about South Korea’s education policy consist of problems that arise from different genres of discourses that in turn belong to different historical moments and education values. I engage in a media discourse analysis of the reportage on South Korean international sport celebrity Yuna Kim that highlight the key education debates currently taking place in South Korea. First, I deal with the neologism umchinttal (my mom’s friend’s daughter) as an ideal student type. The use of the neologism suggests that students without familial cultural or economic capital do not have as much social mobility through education compared to the previous generation of students. Second, I look at the changing student-parent-teacher relationship through the controversy about Kim’s decision to part ways with her former coach Brian Orser.
