Underwater targets recognition was one of the important and difficult topics of underwater acoustic signal processing. It was of important to extract and analysis the nonlinear and chaotic feature of ship radiated noise and recognize underwater target. To solve underwater targets recognition problem, a method based on wavelet packets-fractal and Support Vector Machine (SVM) for underwater target recognition...
Except for daily functions, service Robot in family environment should have more intelligence, one of the most important abilities is to detect the unusual state of clients, and then be able to call for help timely. In order to achieve this, we propose an approach for the service robot to detect unusual state of the elder in a real-time way and construct a solution to the problem of the research model,...
Detecting abnormal state of elder from sensor is very important for high-level activity inference of service robot. This paper proposes a model to solve this problem using location information. Firstly, the feature can be extracted from location information using the SLAM Map, and the vector based on l,thetas is calculated. Then approach of clustering the feature vector based on H-FCM algorithm. Experiment...
