A learning-based method to detect and segment text from scene images

This paper proposes a learning-based method for text detection and text segmentation in natural scene images. First, the input image is decomposed into multiple connected-components (CCs) by Niblack clustering algorithm. Then all the CCs including text CCs and non-text CCs are verified on their text features by a 2-stage classification module, where most non-text CCs are discarded by an attentional cascade classifier and remaining CCs are further verified by an SVM. All the accepted CCs are output to result in text only binary image. Experiments with many images in different scenes showed satisfactory performance of our proposed method.

An Evolution of the Migration of Taiwanese Female Basketball Players: From the ‘American Dream’ to the ‘Chinese Dream’

Abstract

This paper explores the migration of female basketball players from Taiwan to China. Governance theory is adopted as the framework in this study to analyze the phenomenon of players’ migration and to understand how it was shaped over the years. The empirical work draws on a qualitative approach, which is based on a review of documentary materials and semi-structured interviews; coding and analysis were undertaken with a content analysis approach in order to investigate the decision-making processes and their consequences for the players’ migration. The feature of systematic governance for the development of women’s basketball has been revealed in this study. Stakeholders with personal interests caused the downturn of women’s basketball development in Taiwan, and it eventually led to the players’ migration abroad. Through the lens of governance theory, it has been revealed that a number of factors – namely, political, financial, personal, socio-economic, and cultural – all intertwine with one another dynamically to influence the female players’ decision to move abroad. This finding broadens the scope for the research of Taiwanese athletes’ migration to China, extending the focus from only business or industry to other aspects, thereby highlighting the fact that the subject is more complex than previously understood.     

高校学生机房管理模式的探索与实践

普通高校机房承担着大量的教学与科研任务,用户上机的目的、需求复杂,常常给机房管理人员带来较繁重的工作负担。针对这种情况,我们应用Windows2000核心管理工具——智能镜像(IntelliMirror)技术,使用活动目录(ActiveDirectory)和组策略(GroupPolicy),用以加强对用户桌面的策略性管理,较好地解决了对用户在使用和需求上的管理;提高了机房服务质量。     

众包模式下参与动机对参与意愿的影响研究——基于金钱激励强度及任务复杂程度的视角

通过实验的方法探讨任务复杂程度对参与者动机的调节作用,并采用三组对照实验探索在不同金钱奖励情况下,任务复杂程度的调节作用是否会发生改变;同时,从实证角度探讨“挤出效应”是否存在.被试者通过众包任务情境模拟来回答量表问题,利用smartPLS进行数据分析和模型验证.结果表明,任务复杂程度负向调节内外动机对参与意愿的影响,且内外动机之间确实存在“挤出效应”.此外,在不同的金钱激励强度下,任务复杂程度对内外动机的调节作用不同.

A review of tennis racket performance parameters

The application of advanced engineering to tennis racket design has influenced the nature of the sport. As a result, the International Tennis Federation has established rules to limit performance, with the aim of protecting the nature of the game. This paper illustrates how changes to the racket affect the player-racket system. The review integrates engineering and biomechanical issues related to tennis racket performance, covering the biomechanical characteristics of tennis strokes, tennis racket performance, the effect of racket parameters on ball rebound and biomechanical interactions. Racket properties influence the rebound of the ball. Ball rebound speed increases with frame stiffness and as string tension decreases. Reducing inter-string contacting forces increases rebound topspin. Historical trends and predictive modelling indicate swingweights of around 0.030–0.035 kg/m² are best for high ball speed and accuracy. To fully understand the effect of their design changes, engineers should use impact conditions in their experiments, or models, which reflect those of actual tennis strokes. Sports engineers, therefore, benefit from working closely with biomechanists to ensure realistic impact conditions.     

Synchronized lower limb kinematics with pelvis orientation achieves the non-rotational shot

A non-rotational (NR) shot is now a well-known scoring move in soccer. To execute the NR shot, it is necessary to deprive the ball of any rotational forces during the impact phase. To execute the NR shot, it is natural that the force vector acting from the foot would pass through the ball’s center of gravity; however, the coordinated motion of the lower limb joint’s angular displacement and the pelvis is still unclear. The aim of this study is to estimate the coordinated leg and pelvis motion during the NR shot as compared to that during instep kicking. Four right-leg dominant college league players were asked to perform a NR shot and an instep kick a total of 10 times each. Hip, knee, and ankle joint angular displacements in the sagittal plane and pelvis yaw and roll rotational motions during both types of kicks were calculated with 14 IR reflective markers using a 3D real-time motion analysis system with a 250-Hz sampling. The Euclidean distances of the joint space of the NR shot and the instep kick were also calculated to detect similarities in the coordinated motion of the lower limb. The results showed that the lower limb joint motions in the sagittal plane were not different; however, the pelvis roll and yaw motions were apparently different, and these phenomena could simulate a pendulum motion with changes in both the vertical and horizontal displacements. These results suggest that the coordinated motion of the lower limb joint’s angular displacement shows high similarity between the NR shot and the instep kick, and the pelvis roll and yaw synchronized orientation is essential for achieving the NR shot.
