The non-stationary character of the acoustic signals and the overlapping issue of blockage features can be challenging for condition detection of the underground water supply pipes. Aiming to solve the above problems, a method including feature extraction and pattern recognition based on multivariate empirical mode decomposition (MEMD) and approximate entropy was proposed in this paper. Firstly, the...
We present a new gait identification method based on dynamic time warping (DTW), as video surveillance system requires high accuracy and precision. It could reduce computational cost of gait recognition, significantly improve the recognition rate for gait and meet the demand of video surveillance. The characters of human appearance have been utilized to extract entire binary image of human silhouette...
