First arrival time picking for microseismic data based on shearlet transform
Automatic identification and first arrival time picking of microseismic data play an important role in microseismic monitoring technology, and it is the precondition for real-time microseismic hypocenter location. This paper presents a novel first arrival time picking method based on shearlet transform (ST), which aims to get satisfactory results in low signal-to-noise ratio data. The ST is use...
متن کاملON THE SHEARLET TRANSFORM USING HYPERBOLIC FUNCTIONS
In this paper, we focus on the study of shearlet transform which isdened by using the hyperbolic functions. As a result we check an admissibilitycondition such that implies the reconstruction formula. To this end, we will usethe concept of the classical shearlet, which indicates the position and directionof a singularity.
متن کاملDenoising Method Based on the Nonsubsampled Shearlet Transform
In this paper, a new bivariate shrinkage denoising method is proposed to model statistics of shearlet coefficients of images. Using Bayesian estimation theory we derive from this model a simple non-linear shrinkage function for shearlet denoising, which generalizes the soft threshold approach. Experimental results show that the proposed method can remove Gaussian white noise while effectively p...
متن کاملCompressed Sensing Image Reconstruction Based on Discrete Shearlet Transform
The two-dimensional wavelet transform for magnetic resonance imaging (MRI) images does not sparsely represent curve singularity characteristics, which can only capture the limited direction information. Pointing at this problem, this paper presents a new method based on discrete Shearlet transform for compressed sensing MRI (CS-MRI). Frequency coefficients can be got at all scales and in all di...
