We present a computer vision system for tracking players in indoor team games, e.g. handball in our particular case. We describe several image processing and tracking methods, along with camera calibration and lens distortion correction. The output of the system consists of spatio-temporal trajectories of the players, which can be further processed and analyzed by sport experts. We present some...

Sports are an important part of nowadays society and there is an increasing interest by the sports’ community on having mechanisms that allow them to better understand the dynamics of teams (their own and their opponents). This information is frequently extracted manually by operators that, after the game, visualize game recordings (frequently TV footages) and perform hand annotation, which is ...

gesture and motion recognition are needed for a variety of applications. the use of human hand motions as a natural interface tool has motivated researchers to conduct research in the modeling, analysis and recognition of various hand movements. in particular, human-computer intelligent interaction has been a focus of research in vision-based gesture recognition. in this work, we introduce a 3-...

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...

Brand logo detection is a special aspect of machine vision. However, Video benchmarks are scarce in the public domain. We exploit power deep convolutional neural network (DCNN) and leverage established datasets related to existing applications develop deep-transfer active-learning (DTAL) algorithm select most valuable samples so that smallest number possible needs be labeled achieve maximum per...

Kinetic vision acuity (KVA) is an index developed in Japan that refers to the capacity recognize a moving object moves back and forth against observer. This review outlines history of KVA studies on conducted at Faculty Health Sports Science Juntendo University, i.e. characteristics athletes, factors associated with KVA, sports age-dependent decline effects docosahexaenoic acid (DHA) astaxanthi...

BACKGROUND Extracurricular school-based sports are considered to be an ideal means of reaching children who are not active in community sports. The purposes of this study were to examine the extent to which pupils not engaging in community sports do participate in extracurricular school-based sports, and to assess whether extracurricular school-based sports participants are more physically acti...

The main goal of this research is to study in detail the main characteristics of university students in order to find out the reasons why they have adopted an inactive lifestyle. In order to do so, a questionnaire on the analysis of sports habits and lifestyle was given to 323 students. They were taken from a representative sample of 1834 students. These 323 students had pointed out at the mome...
