Intelligent Transportation System is a worldwide research hotspot and the extraction of traffic parameters is a crucial part of it for subsequent identification of traffic states. This paper proposes a novel approach of extracting traffic parameters such as time occupancy, volume and vehicle velocity based on video images. Visual features obtained from spatio-temporal images are more immune to environmental...
Road surface condition is very important for safe driving especially in bad weather such as snow or rainy. In this paper we proposed a video camera road image status detection method. The color and texture information of the road surface is extracted from the video frame and then we build a naïve Bayesian classifier to classify the road surface image into three categories, dry, mild snow coverage,...
Dynamic tracing and trace replay are two main functions in vehicle monitoring system of GIS. Based on the idea of line-to-point set, "point-to-point" road matching algorithm and "Trace interpolation" trace replay algorithm are designed and implemented. The main idea of "Point-to-point" is that the road will be separated into a series of discrete set points, and then got...
