Note on the Existence of Minimizers for Variational Geometric Active Contours
El Hadji S. Diop, Valérie Burdin, V. B. Surya Prasath
We propose here a proof of existence of a minimizer of a segmentation functional based on a priori information on target shapes, and formulated with level sets. The existence of a…
Deep Learning for Medical Image Registration: A Comprehensive Review
Subrato Bharati, M. Rubaiyat Hossain Mondal, Prajoy Podder +1
Image registration is a critical component in the applications of various medical image analyses. In recent years, there has been a tremendous surge in the development of deep lear…
Deep learning for identification and face, gender, expression recognition under constraints
Ahmad B. Hassanat, Abeer Albustanji, Ahmad S. Tarawneh +6
Biometric recognition based on the full face is an extensive research area. However, using only partially visible faces, such as in the case of veiled-persons, is a challenging tas…
Medical Imaging with Deep Learning for COVID- 19 Diagnosis: A Comprehensive Review
Subrato Bharati, Prajoy Podder, M. Rubaiyat Hossain Mondal +1
The outbreak of novel coronavirus disease (COVID- 19) has claimed millions of lives and has affected all aspects of human life. This paper focuses on the application of deep learni…
Validation of Tsallis Entropy In Inter-Modality Neuroimage Registration
Henrique Tomaz Amaral-Silva, Luiz Otavio Murta-Jr, Paulo Mazzoncini de Azevedo-Marques +3
Medical image registration plays an important role in determining topographic and morphological changes for functional diagnostic and therapeutic purposes. Manual alignment and sem…
Polyp Detection and Segmentation from Video Capsule Endoscopy: A Review
V. B. Surya Prasath
Video capsule endoscopy (VCE) is used widely nowadays for visualizing the gastrointestinal (GI) tract. Capsule endoscopy exams are prescribed usually as an additional monitoring me…
On time adaptive critical variable exponent vectorial diffusion flows and their applications in image processing
V. B. Surya Prasath, D. Vorotnikov
Variable exponent spaces have found interesting applications in real world problems. Recently, there have been considerable interest in utilizing variational and evolution problems…
Adaptive diffusion constrained total variation scheme with application to `cartoon + texture + edge' image decomposition
Juan C. Moreno, V. B. Surya Prasath, D. Vorotnikov +2
We consider an image decomposition model involving a variational (minimization) problem and an evolutionary partial differential equation (PDE). We utilize a linear inhomogenuous d…
On Convergent Finite Difference Schemes for Variational - PDE Based Image Processing
V. B. S. Prasath, Juan C. Moreno
We study an adaptive anisotropic Huber functional based image restoration scheme. By using a combination of L2-L1 regularization functions, an adaptive Huber functional based energ…
Robust Periocular Recognition By Fusing Sparse Representations of Color and Geometry Information
Juan C. Moreno, V. B. S. Prasath, Gil Santos +1
In this paper, we propose a re-weighted elastic net (REN) model for biometric recognition. The new model is applied to data separated into geometric and color spatial components. T…
Radar shadow detection in SAR images using DEM and projections
V. B. S. Prasath, O. Haddad
Synthetic aperture radar (SAR) images are widely used in target recognition tasks nowadays. In this letter, we propose an automatic approach for radar shadow detection and extracti…
Brain MRI Segmentation with Fast and Globally Convex Multiphase Active Contours
Juan C. Moreno, V. B. S. Prasath, Hugo Proenca +1
Multiphase active contour based models are useful in identifying multiple regions with different characteristics such as the mean values of regions. This is relevant in brain magne…
Color image denoising by chromatic edges based vector valued diffusion
V. B. Surya Prasath, Juan C. Moreno, K. Palaniappan
In this letter we propose to denoise digital color images via an improved geometric diffusion scheme. By introducing edges detected from all three color channels into the diffusion…
On a coupled PDE model for image restoration
V. B. Surya Prasath, Dmitry Vorotnikov
In this paper, we consider a new coupled PDE model for image restoration. Both the image and the edge variables are incorporated by coupling them into two different PDEs. It is sho…
