In order to improve the traffic data's completeness and comprehensiveness, this paper presents a traffic information fusion method to solve the problem of road sections without GPS sampling signals. A Kalman filter method is used to fuse the information of associated road sections with traffic information to acquire the speed information of those road sections without GPS sampling signals. The fusion...
Osteoarthritis is characterised by functional failure of synovial joints. It is directly related to degeneration and malfunction of articular cartilage. Earlier studies have reported that normal articular cartilage contains a 3D collagen network integrated with interwoven collagen bundles in the superficial zone. The collagen bundles are critical to the tensile and shearing resistance of articular...
Classifying network traffic according to the applications is important to a broad range of network areas. Compared with the traditional method which classifies traffic using predefined well-known port numbers, the method using application signatures is more accurate. Unfortunately, analyzing signatures and maintaining up-to-date signatures for various applications is very difficult. To solve the problem,...
With the development of polymorphic worms, worms do greater harm to networks. The content-based signature generation of polymorphic worms has been a challenge for network security. This paper presents a fast signature generation method for polymorphic worms. The main feature of this method is clustering network normal traffic to create a white list before carrying out a comprehensive analysis of malicious...
This paper presents a real-time robust algorithm to detect and accurately locate the circular objects in digital images. The algorithm consists of four steps.First the edge pixels are extracted using Canny edge detection algorithm followed by a noise removal process to remove the non-circle edge points.Afterwards, a direct least square fitting algorithm is developed to calculate radius and circle...
