Semantic event and slow motion replay extraction for sports videos have become hot research topics. Most researches analyze every video frame; however, semantic events only appear in frames with scoreboard, whereas replays only appear in frames without scoreboard. Extracting events and replays from unrelated frames causes defects and leads to degradation of(More)
BACKGROUND AND PURPOSE The epidemiology of coxsackievirus has rarely been investigated in Taiwan. This study was performed to ascertain the epidemiological and clinical characteristics of coxsackievirus infections in Taiwan. METHODS 457 patients treated at a medical center in northern Taiwan who were positive for coxsackievirus were enrolled in this(More)
One of the key challenges of next-generation wireless networks (such as enhanced general packet radio service) is the ability to provide different grades of quality of service to users. Weighted fair queueing (WFQ) is a popular scheduling algorithm to guarantee bounded delay, guaranteed throughput, and fairness. However, adapting the WFQ scheduler to(More)
The purposes of this study were to (1) examine the relationship between the number of various types of healthy remaining natural teeth at different sites and self-rated chewing ability and (2) evaluate the relationship between the number of functional tooth units (FTUs), comprising functional natural teeth (FNT) or fixed prostheses, and self-rated chewing(More)
OBJECTIVES The aim of this study was to evaluate a screening test based on a food intake questionnaire to discriminate the masticatory ability of Taiwanese older adults with 20 and more natural teeth and at least 8 functional tooth units (FTUs) from the masticatory ability of those with fewer than 20 natural teeth and 8 FTUs. MATERIALS AND METHODS The(More)
Semantic event extraction is helpful for video annotation and retrieval. For sports video, most previous works detect events by video content itself. Some useful external knowledge has been researched recently. In this paper, we proposed an unsupervised approach to extract semantic events from sports webcast text. First, unrelated words in the descriptions(More)
Surgical emphysema is an uncommon but potentially serious complication of third molar removal and other oral procedures. The purpose of this case report is to remind dentists of the risk of surgical emphysema. Surgical emphysema developed in a 32-year-old female after removal of a mandibular third molar using a high-speed dental hand-piece. Because of the(More)
This study used independent component analysis (ICA) to decompose the surrogate image data by concatenating in space multiple subjects' anatomical images after spatial normalization and smoothing to make all images in the same space. The multiple-subject anatomical image data included three different subject/patient populations, namely the Parkinson's(More)
Surgical removal of the mandibular third molar is a regular surgical procedure in dental clinics, and like all operations, it may have some complications, such as infection, bleeding, nerve injuries, trismus and so on. An accidentally displaced lower third molar is a relatively rare complication, but may cause severe tissue injury and medicolegal problems.(More)
