This study is to take the advantage of shadow appearance in Standard Imagery produced from QuickBird for damage detection in urban areas. In a very complex scene of an urban area acquired from very high resolution satellite-based optical sensors, fortunately, the buildings tend to align in some dominant directions in a small area and posses geometric(More)
In this paper, water tap usage is examined based on water sound analysis. We focus on detecting gwater wasteh to make persuasion of water savings effective, where two types of water waste are defined: inter-activity water waste and intra-activity water waste. Based on a preliminary user survey, four types of basin-related activities are(More)
Towards persuasive system for efficient use of water resource, we propose a method to detect "water waste" among water-related activities based on water sound analysis. We supposed two types of water-wastes: inter-activity water waste and intra-activity water waste. An evaluation with a variety of experimental conditions presents that the aggregate(More)
