Breast cancer detection in mammography images using Neighborhood Attention transformer and Shearlet Transform

Comput. Biol. Medicine
Breast cancer is a leading cause of cancer-related deaths among women. Advances in early diagnosis and treatment, particularly through screening mammography, have reduced mortality rates by enabling the detection of small tumors.

THE UNCERTAINTY PRINCIPLE ASSOCIATED WITH THE CONTINUOUS SHEARLET TRANSFORM

International Journal of Wavelets, Multiresolution and Information Processing, 2008
Finding optimal representations of signals in higher dimensions, in particular directional representations, is currently the subject of intensive research. Since the classical wavelet transform does not provide precise directional information in the sense of resolving the wavefront set, several new representation systems were proposed in the past ...

On the shearlet transform using hyperbolic functions

2014
Summary: In this paper, we focus on the study of shearlet transform which is defined by using the hyperbolic functions. As a result, we check an admissibility condition such that implies the reconstruction formula. To this end, we use the concept of the classical shearlet, which indicates the position and direction of a singularity.

Shearlet and contourlet transforms for analysis of electrocardiogram signals

Computer Methods and Programs in Biomedicine, 2018
Cardiac arrhythmia is an abnormal variation in the heart electrical activity that affects millions of people worldwide. Electrocardiogram (ECG) signals have been widely used to assess and diagnose cardiac abnormalities.A novel methodology based on shearlet and contourlet transforms for automatically classify an input ECG signal into different heart ...

Regularized Full-Waveform Inversion With Shearlet Transform and Total Generalized Variation

IEEE Transactions on Geoscience and Remote Sensing
Full-waveform inversion (FWI) is a powerful method of reconstructing subsurface properties during seismic exploration. However, it is difficult for FWI to accurately describe a subsurface model with sharp surfaces and smooth variations because of the ...

Multimodal Medical Image Fusion Using Nonsubsampled Shearlet Transform and Smallest Uni-Value Segment Assimilating Nucleus

International journal of pattern recognition and artificial intelligence, 2022
This paper presents a new fusion scheme for medical (CT-MRI) images which is based on the nonsubsampled shearlet transform (NSST). The various image pairs to be fused are obtained from primary and internet sources.

Adaptive Nonsubsampled Shearlet Transform and Its Application to Surface Wave Suppression

IEEE Transactions on Geoscience and Remote Sensing
This article proposes a new surface wave suppression method based on nonsubsampled Shearlet transform (NSST). First, we use a frequency wavenumber (FK) Filter to extract surface wave noise from seismic data. We then apply a Shearlet transform to both the

A saliency detection model using shearlet transform

Multimedia Tools and Applications, 2014
Visual attention is a mechanism to derive possible locations of objects or regions from natural scenes, and many studies have tried to simulate this mechanism to build saliency detection models, which would accelerate the course of many applications, such as object location, detection and recognition, image segmentation, retrieval and so on.
