Blind Image Watermark Detection Algorithm Based on Discrete Shearlet Transform Using Statistical Decision Theory [PDF]

open access: yes, 2018
Blind watermarking targets the challenging recovery of the watermark when the host is not available during the detection stage. This paper proposes Discrete Shearlet Transform (DST) as a new embedding domain for blind image watermarking.

Apply hyperanalytic shearlet transform to geometric separation [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2014
This paper first proposes a novel image separation method based on the hyperanalytic shearlet. By combining the advantages of both the hyperanalytic wavelet transform and the shear operation, hyperanalytic shearlet is easy to implement and also has a low redundancy.

Radon transform inversion using the shearlet representation [PDF]

open access: yes, 2010
The inversion of the Radon transform is a classical ill-posed inverse problem where some method of regularization must be applied in order to accurately recover the objects of interest from the observable data. A well-known consequence of the traditional

Shearlet-based loop filter

open access: yes, 2022
S.141-145In 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 ...

Shearlet transform and convolutional neural network for histopathology images in breast cancer classification [PDF]

open access: yes
Breast cancer stands out as one of the global health threats, as it may cause death if improperly treated. Thus, detecting the illness at the early stage through precise diagnosis is important to prevent progression of tumors with effective treatments ...

Video text localization using wavelet and shearlet transforms [PDF]

open access: yesSPIE Proceedings, 2013
Text in video is useful and important in indexing and retrieving the video documents efficiently and accurately. In this paper, we present a new method of text detection using a combined dictionary consisting of wavelets and a recently introduced transform called shearlets.

Bendlets: A second-order shearlet transform with bent elements [PDF]

open access: yesApplied and Computational Harmonic Analysis, 2019
We introduce bendlets, a shearlet-like system that is based on anisotropic scaling, translation, shearing, and bending of a compactly supported generator. With shearing being linear and bending quadratic in spatial coordinates, bendlets provide what we term a second-order shearlet system.

Corner detection based on shearlet transform and multi-directional structure tensor

open access: yes, 2020
Image corners have been widely used in various computer vision tasks. Current multi-scale analysis based corner detectors do not make full use of the multi-scale and multi-directional structural information.
