Restoration Guarantee of Image Inpainting via Low Rank Patch Matrix Completion
Jian-Feng Cai, Jae Kyu Choi, Jingyang Li +1
In recent years, patch-based image restoration approaches have demonstrated superior performance compared to conventional variational methods. This paper delves into the mathematic…
Approximation Theory of Wavelet Frame Based Image Restoration
Jian-Feng Cai, Jae Kyu Choi, Jianbin Yang
In this paper, we analyze the error estimate of a wavelet frame based image restoration method from degraded and incomplete measurements. We present the error between the underlyin…
Two Stage Continuous Domain Regularization for Piecewise Constant Image Restoration
Jian-Feng Cai, Jae Kyu Choi, Chenchuan Zhou
The finite-rate-of-innovation (FRI) framework which corresponds a signal/image to a structured low-rank matrix is emerging as an alternative to the traditional sparse regularizatio…
Approximation Theory of Total Variation Minimization for Data Completion
Jian-Feng Cai, Jae Kyu Choi, Ke Wei
Total variation (TV) minimization is one of the most important techniques in modern signal/image processing, and has wide range of applications. While there are numerous recent wor…
Dipole Incompatibility Related Artifacts in Quantitative Susceptibility Mapping
Liangdong Zhou, Jae Kyu Choi, Youngwook Kee +2
Artifacts in quantitative susceptibility mapping (QSM) are analyzed to establish an optimal design criterion for QSM inversion algorithms. The magnetic field data is decomposed int…
