In this paper we propose a robust method of displaying the archery score in real time by using image processing techniques to aid for the development of an automated scoring system after archers shoot arrows. Some experimental results are shown by using video sequences taken in an indoor environment.
We have examined the diffusion of zinc (Zn) into ruthenium-doped indium phosphide (Ru-InP), which is used as the current blocking layer in buried heterostructure (BH) lasers. By applying a p-InP (Zn-doped InP)/Ru-InP/p-InP structure to the blocking layers of BH lasers, excellent laser characteristics can be obtained. Several epitaxial techniques have been used to suppress the degradation of the current...
Kommt das Thema „Japaner und Arbeit“ zur Sprache, so denkt man sofort an lange Arbeitszeiten, freiwillige Überstunden und „Karoshi“, den Tod durch Überarbeitung. Urlaub gibt es kaum und wenn, dann im „Schnelldurchlauf“: acht europäische Städte in sechs Tagen beispielsweise. Japanische Männer haben keine Hobbys und liegen nach der Pensionierung dann wie „Sperrmüll“ untätig im Haus herum.
This paper proposes an image processing approach to automatic scoring system for archery targets. Specifically, the proposed system first performs Morphological operations on the target image to obtain thick boundaries of the arrow hits and then the image segmentation process is applied to segment the target area by using color and shape features. In doing so, a dynamic thresholding is applied to...
The archery sight-system is developed for visually impaired persons. The system is based on the magnetic directional sensors for earth magnetism. Both azimuth and elevation angles to the target are measured by the sensor equipped on the archery bow. The sensed information is transmitted to the receiver, which is located near the archer. The sound interface in the receiver transforms the sensed information...
Recently multimedia applications such as music or video streaming, video teleconferencing and IP telephony have been flourishing in packet-switched networks. Applications that generate such real-time data can have very diverse quality-of-service (QoS) requirements. In order to guarantee diverse QoS requirements, the combined use of a packet scheduling algorithm based on Generalized Processor Sharing...
Employing rectangular TO-CAN and optimizing coupling mode of transmission line realize both TEC power consumption of 0.6 W at 90??C and superior optical output waveform with ask margin of 24% at 10.7 Gbit/s.
