Urban functional zones refer to areas (or regions) of a city which provide specific urban functions for peoples who lived in the city. The spatial layout of buildings in functional zone show a specific pattern, e.g. residual areas usually have similar builds and the positions of which are highly organized. In this paper, we show that it is possible to identify urban functional zones from a remote...
The algorithm to find the novelty temporal pattern from the temporal database is presented. The basic idea of the algorithm is firstly to extract the feature sequence from a time series, then to compare the feature points of the time series with ones of the normal pattern to decide whether there is a novelty pattern in the time series. The temporal relation of time series is reserved in the feature...
Driver fatigue is one of the main reasons causing traffic accidents. Yawning is an important character of driver fatigue. Mouth geometric character represents state of driver. So driver's mouth detection and information extraction is especially important. This paper proposes to locate and track driver's mouth using two CCD cameras to detect driver's fatigue in real-time. One of them is with cloud...
