In this paper, we present a real-time multi-objects tracking system which can detect various types of moving objects in image sequences of traffic video obtained from a stationary video camera. Using the adaptive background reconstruction technique can effectively handle with environmental changes and obtain good results of objects extraction. Besides, we introduce a robust region- and feature-based tracking algorithm with plentiful features to track correct objects continuously. After tracking objects successfully, we can analyze the tracked objects' properties and recognize their behavior for extracting some useful traffic parameters. According to the structure of our proposed algorithms, we implemented a tracking system including the functions of objects classification and accident prediction. Experiments were conducted on real-life traffic video of some intersection and testing datasets of other surveillance research. The results proved the algorithms we proposed achieved robust segmentation of moving objects and successful tracking with objects occlusion or splitting events. The implemented system also extracted useful traffic parameters.

雖然網路活動仍持續的快速成長，但消費對於網路上牽涉金融交易的購物行爲卻踟躕不前，詳究其主因之一即爲消费者不信任網路商店。在網路環境中除了無法直接接觸産品外，非面對面的接觸所造成的陌生感更阻礙消費者的交易意願。盡管金融加密機制已是不可或缺的要件之一，但是對於消費者而言，店家網站相關設計因素。亦是在互動交易的過程影響建立信任的重要因素。尤其是對新進的網路商店而言，在聲譽舆品牌尚未建立起来時，如何透過信任設計因素的安排来提升消費者的初始信任感，可說是非常重要議题。本研究的目的在探討影響消費者於不同交易階段影響其初始信任感之設計因素。研究結果顯示分别在「資訊階段」、「協定階段」舆「社群階段」皆存有明顯影響初始信任之設計因素。
