With the development of high-speed railway, its security problem gained more and more attention. Noise data collected by sensors reflected the operation condition and was close related to the security of train. The efficiency of processing data became significant due to the volume of data growing at an unprecedented rate. It was a challenge to process massive noise data effectively. A method for preprocessing massive noise data based on MapReduce was proposed by use of the idea of parallel computing. The experiments on Hadoop platform prove that the proposed method can improve the efficiency of preprocessing massive noise data.
In order to improve the accuracy of the image annotation, an automatic image annotation method based on mutual K-nearest neighbor graph(MKNN) is proposed. The peoposed algorithm describes the relationship between low-...

In this paper,an iterative regularized super resolution (SR) algorithm considering non-Gaussian noise is *** on the assumption of a generalized Gaussian distribution for the contaminating noise,an lp norm is adopted to measure the data fidelity term in the cost *** the meantime,a regularization functional defined in terms of the desired high resolution (HR) image is employed,which allows for the simultaneous determination of its value and the partly reconstructed image at each iteration *** convergence is thoroughly *** results show the effectiveness of the proposed algorithm as well as its superiority to conventional SR methods.
