Considering stability problems of the current corridor recognition algorithm based on laser scanner, this paper proposes a method for mobile robot fast laser-based corridor recognition. Firstly, Median filter is used to deal with the laser scan to reduce the noise. Then, it employs segmentation method to cluster the data to remove some isolated points. After that, it is feasible to calculate the direction...
The study concerns with classification of acoustic emission signals in composite laminates using support vector machine (SVM). Wavelet packet analysis is performed initially to extract the features and to reduce the dimensionality of original data features. The SVM classifiers are trained with a subset of the experimental data for known fault conditions and are tested using the remaining set of data...
