IET Image Processing, Volume 15, Issue 9, Page 2097-2111, July 2021., 2021 Abstract An extension of Radon transform by using a measure function capturing the user need is proposed. The new transform, called scale space Radon transform, is devoted to the case where the embedded shape in the image is not filiform. A case study is brought on a straight line and an ellipse where the SSRT behaviour in the scale space and in the ...

Image Resolution Enhancement of Highly Compressively Sensed CT/PET Signals
Algorithms, 2020 One of the most challenging aspects of medical modalities such as Computed Tomography (CT) as well hybrid techniques such as CT/PET (Computed Tomography/Positron emission tomography) and PET/MRI is finding a balance between examination time, radiation ...

IET Renewable Power Generation, Volume 15, Issue 8, Page 1662-1677, 8 June 2021., 2021 Abstract The quality of power in modern‐day power system is polluted with increased penetration of converter‐based distributed generations such as wind farm, solar PV system. In such scenarios detection of islanding and power quality disturbances as well as the removal of these from the system is quite crucial for equipment and maintenance personnel ...

MULTISPECTRAL IMAGE FUSION USING SLANTLET-BASED RIDGELET TRANSFORM
Journal of Engineering, 2007 This paper introduces a new method in the multispectral image fusion based on ridgelet transform which represents edges better than wavelets. Since edges play a fundamental rule in image understanding, one good way to enhance spatial resolution is to ...

Automatic eye blink artifact removal for EEG based on a sparse coding technique for assessing major mental disorders [PDF]
Journal of Integrative Neuroscience, 2019 In the electroencephalogram recorded data are often confounded with artifacts, especially in the case of eye blinks. Different methods for artifact detection and removal are discussed in the literature, including automatic detection and removal. Here, an

Recovering edges in ill-posed inverse problems: optimality of curvelet frames [PDF]
, 2002 We consider a model problem of recovering a function $f(x_1,x_2)$ from noisy Radon data. The function $f$ to be recovered is assumed smooth apart from a discontinuity along a $C^2$ curve, that is, an edge.
