Texture Edge detection by Patch consensus (TEP)
Guangyu Cui, Sung Ha Kang
We propose Texture Edge detection using Patch consensus (TEP) which is a training-free method to detect the boundary of texture. We propose a new simple way to identify the texture…
Group projected Subspace Pursuit for Identification of variable coefficient differential equations (GP-IDENT)
Yuchen He, Sung-Ha Kang, Wenjing Liao +2
We propose an effective and robust algorithm for identifying partial differential equations (PDEs) with space-time varying coefficients from a single trajectory of noisy observatio…
Numerical Identification of Nonlocal Potential in Aggregation
Yuchen He, Sung Ha Kang, Wenjing Liao +2
Aggregation equations are broadly used to model population dynamics with nonlocal interactions, characterized by a potential in the equation. This paper considers the inverse probl…
A Lifted Framework for Sparse Recovery
Yaghoub Rahimi, Sung Ha Kang, Yifei Lou
Motivated by re-weighted approaches for sparse recovery, we propose a lifted (LL1) regularization which is a generalized form of several popular regularizations i…
Silhouette Vectorization by Affine Scale-space
Yuchen He, Sung Ha Kang, Jean-Michel Morel
Silhouettes or 2D planar shapes are extremely important in human communication, which involves many logos, graphics symbols and fonts in vector form. Many more shapes can be extrac…
Robust Identification of Differential Equations by Numerical Techniques from a Single Set of Noisy Observation
Yuchen He, Sung Ha Kang, Wenjing Liao +2
We propose robust methods to identify underlying Partial Differential Equation (PDE) from a given set of noisy time dependent data. We assume that the governing equation is a linea…
