    Towards Structured Analysis of Broadcast Badminton Videos

    Full text link
    Sports video data is recorded for nearly every major tournament but remains archived and inaccessible to large scale data mining and analytics. It can only be viewed sequentially or manually tagged with higher-level labels which is time consuming and prone to errors. In this work, we propose an end-to-end framework for automatic attributes tagging and analysis of sport videos. We use commonly available broadcast videos of matches and, unlike previous approaches, does not rely on special camera setups or additional sensors. Our focus is on Badminton as the sport of interest. We propose a method to analyze a large corpus of badminton broadcast videos by segmenting the points played, tracking and recognizing the players in each point and annotating their respective badminton strokes. We evaluate the performance on 10 Olympic matches with 20 players and achieved 95.44% point segmentation accuracy, 97.38% player detection score ([email protected]), 97.98% player identification accuracy, and stroke segmentation edit scores of 80.48%. We further show that the automatically annotated videos alone could enable the gameplay analysis and inference by computing understandable metrics such as player's reaction time, speed, and footwork around the court, etc.Comment: 9 page

    Technological advancements have influenced the way we teach, learn, and communicate in education. Higher educational institutions must continually adapt to emerging technologies by implementing a variety of technologies such as photographs, audio, video, and an endless array of online platforms. Specifically, university physical activity programs, which have existed in higher educational institutions for over a century, are encouraged to incorporate digital media as a means to effectively and efficiently communicate a variety of content areas (Cardinal, 2017; Casey, Goodyear, & Armour, 2017; Tiernan, 2015). The purpose of this case study was to explore the implementation of digital media as a pedagogical tool within physical activity courses (PACs). Eight participants shared their lived experiences as instructors of record for PACs throughout the fall 2019 semester. Results showed the need for digital resources both for the instructor as well as students, the value of digital media as a social connection tool, and the need to use Canvas, video, and audio as pedagogical tools. Professional development opportunities are necessary for PAC instructors to effectively and efficiently implement digital media as a pedagogical tool

    Blogging: the use of digital representation of the migration experience

    Get PDF
    To understand the migrant experience, researchers have traditionally used methods such as ethnography and the analysis of written records to analyse the process of migration; however a new primary source – new-media or digital records – is becoming more and more relevant to the field. The new primary sources take many forms, but a common new-medium, used by those migrating from Greece in the second decade of the twenty-first century, is that of blogs. This preliminary and exploratory study seeks to examine blogs written by people choosing to leave Greece. Using a qualitative analysis of themes extrapolated from blog posts, both personal and practical, this study illustrates themes discussed by bloggers to communicate their experience, and suggests further uses for new-media in the field of migration studies

    WormAssay: A Novel Computer Application for Whole-Plate Motion-based Screening of Macroscopic Parasites

    Lymphatic filariasis is caused by filarial nematode parasites, including Brugia malayi. Adult worms live in the lymphatic system and cause a strong immune reaction that leads to the obstruction of lymph vessels and swelling of the extremities. Chronic disease leads to the painful and disfiguring condition known as elephantiasis. Current drug therapy is effective against the microfilariae (larval stage) of the parasite, but no drugs are effective against the adult worms. One of the major stumbling blocks toward developing effective macrofilaricides to kill the adult worms is the lack of a high throughput screening method for candidate drugs. Current methods utilize systems that measure one well at a time and are time consuming and often expensive. We have developed a low-cost and simple visual imaging system to automate and quantify screening entire plates based on parasite movement. This system can be applied to the study of many macroparasites as well as other macroscopic organisms

    RETHINKING DISCOURSE COMMUNITIES IN THE DIGITAL AGE: THE EFFECTS OF STREAMING ON DISCOURSE OF GAMING COMMUNITIES

    This thesis applies of John Swales’ theory of discourse community (DC) to online streaming sites—a context that creates what this thesis defines as a streamed-discourse community—while examining the context of online streamed discussions, and why they are relevant to rhetorical barriers to digital community building within composition/rhetoric scholarship, especially discourse community research such as Swales\u27 that considers how discourse within a group can create distinct types of communities and social activities

    Exploring Temperament in Beluga Whale Calves (\u3ci\u3eDelphinapterus leucas\u3c/i\u3e)

    Studies of personality and temperament in humans span many disciplines, although animal research is still relatively undeveloped. Research investigating stable individual differences in marine mammals has been limited, and to date there have not been any studies with beluga whales. As an ongoing longitudinal study, seven beluga calves, housed at SeaWorld San Antonio, were videotaped throughout their first two years of life. Four videos were selected from archived video recordings for each calf from the following nine phases: newborn phase (month 1), Q1 (month 2-3), Q2 (month 4-6), Q3 (month 7-9), Q4 (month 10-12), Q5 (month 13-15), Q6 (month 16-18), Q7 (month 19-21), Q8 (month 22-24). Videos were coded for 40 behaviors: three behavioral states, including durations, and 37 behaviors for frequency. These behaviors were later consolidated to 23 behaviors for analysis. A Principal Components Analysis (PCA) of these 23 behaviors across all seven whales yielded a five-factor model for beluga calf temperament. Factors included mother-calf bond, sociability, independence, exploration-vigilance, curiosity-playfulness. A PCA for year one and a PCA from year two were compared and did not yield the same five factors. A paired-samples t-test revealed that five of 26 behaviors were significantly different between year one and year two, and 21 behaviors were significantly different between the newborn phase and year one. While there was only one behavior, orient at researcher, that was not observed in the newborn phase, the calves’ behavior was significantly different during their first month of life. The orient at researcher behavior was observed for the first time around quarter three in all seven whales, signifying a potential milestone. The time the calves spent swimming with their mothers decreased with age, while the time spent swimming socially and swimming alone increased with age. Based on the five-factor model, beluga calves each had their own distinct temperament. While temperament appears to not have stabilized by year two, distinct patterns of behavior were observable in year one and year two. Based on the behavioral patterns of the whales in the first two years of life, it can be argued that beluga calves have distinct temperaments

    In and of the body

    This practice traces information as it moves through physical and digital spaces, asking questions surrounding how technology alters meaning as it makes interpretations. Led by my own personal interests and the memetic bodies of popular culture I was embedded, questions arise surrounding how individuals communicate with and experience the networks they are embedded within. Furthermore, this practice expands to investigate what happens when the body becomes a technological interface, and how issues of ownership affect our interactions

    Teachers Developing Exemplary Inquiry Practices

    Get PDF
    If students are to be successful in the ever-changing scientific world they need to be taught how to think critically, to manipulate materials, and to gather evidence to build knowledge. Most teachers fall short in providing students the inquiry instruction described in the Next Generation Science Frameworks (National Research Council, 2011). This study examined three elementary science teachers’ processes as they developed inquiry practices over time. The Electronic Quality of Inquiry Protocol (EQUIP) was used to gather quantitative and qualitative evidence of the teachers’ inquiry practices in terms of four factors, Curriculum, Instruction, Discourse, and Assessment. A chronological analysis was used to examine the teachers’ professional development and curriculum experiences in relation to their teaching practices. The results showed that all three teachers did change their practice, although the changes varied among cases. For each case, multiple factors influenced the teachers’ development. There was a strong positive correlation between the quality of the teachers’ inquiry practices and the time spent in curriculum-contextualized professional development. This research indicates that when teachers are supported with curriculum and professional development over extended periods, they develop exemplary inquiry practices. Three recommendations are provided for those interested in implementing science education reform
