Proximal Algorithms for Accelerated Langevin Dynamics
Duy H. Thai, Alexander L. Young, David B. Dunson
We develop a novel class of MCMC algorithms based on a stochastized Nesterov scheme. With an appropriate addition of noise, the result is a time-inhomogeneous underdamped Langevin…
Data-driven Identification of Parametric Governing Equations of Dynamical Systems Using the Signed Cumulative Distribution Transform
Abu Hasnat Mohammad Rubaiyat, Duy H. Thai, Jonathan M. Nichols +6
This paper presents a novel data-driven approach to identify partial differential equation (PDE) parameters of a dynamical system. Specifically, we adopt a mathematical "transport"…
Riesz-Quincunx-UNet Variational Auto-Encoder for Satellite Image Denoising
Duy H. Thai, Xiqi Fei, Minh Tri Le +2
Multiresolution deep learning approaches, such as the U-Net architecture, have achieved high performance in classifying and segmenting images. However, these approaches do not prov…
Generalized Intersection Algorithms with Fixpoints for Image Decomposition Learning
Robin Richter, Duy H. Thai, Stephan F. Huckemann
In image processing, classical methods minimize a suitable functional that balances between computational feasibility (convexity of the functional is ideal) and suitable penalties…
Directional Mean Curvature for Textured Image Demixing
Duy Hoang Thai, David Banks
Approximation theory plays an important role in image processing, especially image deconvolution and decomposition. For piecewise smooth images, there are many methods that have be…
Multiphase Segmentation For Simultaneously Homogeneous and Textural Images
Duy Hoang Thai, Lucas Mentch
Segmentation remains an important problem in image processing. For homogeneous (piecewise smooth) images, a number of important models have been developed and refined over the past…
Simultaneous Inpainting and Denoising by Directional Global Three-part Decomposition: Connecting Variational and Fourier Domain Based Image Processing
Duy Hoang Thai, Carsten Gottschlich
We consider the very challenging task of restoring images (i) which have a large number of missing pixels, (ii) whose existing pixels are corrupted by noise and (iii) the ideal ima…
Directional Global Three-part Image Decomposition
Duy Hoang Thai, Carsten Gottschlich
We consider the task of image decomposition and we introduce a new model coined directional global three-part decomposition (DG3PD) for solving it. As key ingredients of the DG3PD…
Global Variational Method for Fingerprint Segmentation by Three-part Decomposition
Duy Hoang Thai, Carsten Gottschlich
Verifying an identity claim by fingerprint recognition is a commonplace experience for millions of people in their daily life, e.g. for unlocking a tablet computer or smartphone. T…
Filter Design and Performance Evaluation for Fingerprint Image Segmentation
Duy Hoang Thai, Stephan Huckemann, Carsten Gottschlich
Fingerprint recognition plays an important role in many commercial applications and is used by millions of people every day, e.g. for unlocking mobile phones. Fingerprint image seg…
