Channel Edge Detection Based On 2D Compactly-Supported Shearlets, An Application to a Channelized Seismic Data in South Caspian Sea

, 2017
Summary Shearlet transform, as a multi-scale and multi-directional transformation is highly capable of detecting features with different dips and has found several applications in image processing tasks.

Shearlets as Multi-scale Radon Transforms

Sampling Theory in Signal and Image Processing, 2017
We show that the 2D-shearlet transform is the composition of the affine Radon transform, a 1D-wavelet transform and a 1D-convolution.

Optimally Sparse Multidimensional Representation Using Shearlets

SIAM Journal on Mathematical Analysis, 2007
In this paper we show that shearlets, an affine-like system of functions recently introduced by the authors and their collaborators, are essentially optimal in representing 2-dimensional functions f which are $C^2$ except for discontinuities along $C^2 ...

Shearlet Coorbit Theory

2015
In this chapter, we will provide a comprehensive overview of shearlet coorbit theory. We will present an almost self-contained introduction into coorbit theory which is the basis for all our investigations. We also discuss the group theoretical background of the continuous shearlet transform, and we explain how the shearlet transform can be combined ...

Face recognition using Shearlets

2012 IEEE 7th International Conference on Industrial and Information Systems (ICIIS), 2012
In this paper we propose a novel statistical face recognition method that uses a new multiresolution analysis called Shearlet transform for facial texture features representation. In recent years Shearlet transform has emerged as the most successful framework for the efficient representation of multidimensional data in which directional information is ...

The Discrete Shearlet Transform: A New Directional Transform and Compactly Supported Shearlet Frames

IEEE Transactions on Image Processing, 2010
It is now widely acknowledged that analyzing the intrinsic geometrical features of the underlying image is essential in many applications including image processing. In order to achieve this, several directional image representation schemes have been proposed.

Biorthogonal Multiresolution Analysis of Shearlets

2009 First International Conference on Information Science and Engineering, 2009
In this paper, we will give the framework of biorthogonal multiresolution analysis of shearlets in two dimensions, and study associated mathematical properties. Then, we will generalize the classical cascade algorithm.

Shearlet-based Loop Filter

2018 26th European Signal Processing Conference (EUSIPCO), 2018
In video coding, in-loop filtering has attracted attention due to its increasing coding performances. In this paper the shearlet-based loop filter is proposed using a sparsifying transform, the shearlet transform, which can identify the important structures of natural images such as edges in the sparse transform domain.

Shearlet Features for Pedestrian Detection

Journal of Mathematical Imaging and Vision, 2018
A long-time, hand-crafted features governed by a directional image analysis have been the base for the best performing pedestrian detection algorithms. In the past few years, approaches using convolutional neural networks have taken over the leadership concerning detection quality.
