Field-pipelines leakage detection based on the negative pressure wave theory is mainly aiming to effectively process pressure sample signal in time domain. Previous methods often perform well for detecting large leakage but poorly for small leakage. In this paper, an alternative way using a particular morphological filter constructed by basic morphological operators is considered. The particular filter...
Because the most algorithms of real color image enhancement did not relate to the spectral sensitivity of most people vision, the color restoration functions of some real color image enhancement algorithms are greatly at random and not proved, and the enhanced real color images which are based on illumination-reflectance model have the loss of details and the dasiahalospsila, we proposed a new algorithm...
Because the color restoration functions of real color image enhancement are greatly at random and not proved, and the enhanced real color images which are based on illumination-reflectance model have the loss of details and the 'halos', we proposed a new algorithm to overcome these disadvantages. Firstly, we transform the real color image from RGB space to HSV space which is approximately orthonormal...
This paper gives a new way of recognizing and sorting of ECG signals, using ECG signals analysis and improved back propagation artificial neural network. Firstly, the ECG signals has to be digitally filtered to eliminating the 50 Hz noise. The neural network adopted is improved back propagation three-layer artificial neural network, with an optimized BPN4-3-2 network topology. Get the four characteristic...
This paper presents a low complexity design scheme of interpolation filter. The proposed scheme is based on that of our previous paper[6], and the new interpolator design algorithm is modified to symmetrize symmetries the coefficients based on Farrow structure. The interpolator has the advantage of low complexity, high implementation efficiency and more stable performance. In contrast with the same...
This paper describes a high-precision, scan-matching-based approach to tracking the pose of mobile vehicle, in which 3D information is added to the MCL algorithm for the first time. The approach is outstanding in terms of accuracy and computation time, which is achieved by improvements of ICP and MCL algorithm. The implemented approach is evaluated with a serious of experiments, and experimental results...
