This paper aims at constructing a good graph to discover the intrinsic data structures under a semisupervised learning setting. First, we propose to build a nonnegative low-rank and sparse (referred to as NNLRS) graph for the given data representation. In particular, the weights of edges in the graph are obtained by seeking a nonnegative low-rank and sparse reconstruction coefficients matrix that...
This paper investigates the masking efficiency of a new sound masker named echo-time-reversed masker. The masker is obtained by generating an acoustic echo from the target speech and then processing it with time reversal method. The masking efficiency of the echo-time-reversed masker is evaluated by two objective intelligibility measurements, i. e. the perceptual evaluation of speech quality (PESQ)...
Aiming at solving the noise problem which had lowered the accuracy in the target detection result from the process of image-collection and image-transmission, the paper proposes a new target detection algorithm based on the improved wavelet threshold. Firstly, these images are filtered by a denoising method, which combines the wavelet threshold method with the correlation of the wavelet coefficients,...
Graphic Processing Unit (GPU) has involved into a parallel computation for it's massively multi threaded architecture. Due to its high computational power, GPU has been used to deal with many problems that can be easily parallelized. This paper will present a GPU based spot noise parallel algorithm for 2D vector field visualization. It uses spot noise method with GPU resources and compute unified...
