Kernel Correlation-Dissimilarity for Multiple Kernel k-Means Clustering

no code implementations6 Mar 2024 Rina Su, Yu Guo, Caiying Wu, Qiyu Jin, Tieyong Zeng

The main objective of the Multiple Kernel k-Means (MKKM) algorithm is to extract non-linear information and achieve optimal clustering by optimizing base kernel matrices.


Matrix Completion-Informed Deep Unfolded Equilibrium Models for Self-Supervised k-Space Interpolation in MRI

no code implementations24 Sep 2023 Chen Luo, Huayu Wang, Taofeng Xie, Qiyu Jin, Guoqing Chen, Zhuo-Xu Cui, Dong Liang

However, most of these methods are tailored for supervised learning scenarios that necessitate fully sampled labels, which can pose challenges in practical MRI applications.

Convex Latent-Optimized Adversarial Regularizers for Imaging Inverse Problems

no code implementations17 Sep 2023 Huayu Wang, Chen Luo, Taofeng Xie, Qiyu Jin, Guoqing Chen, Zhuo-Xu Cui, Dong Liang

We utilize it as a convex regularizer to formulate a CLEAR-informed variational regularization model that guides the solution of the imaging inverse problem on the real data manifold.

Image Denoising by Gaussian Patch Mixture Model and Low Rank Patches

no code implementations20 Nov 2020 Jing Guo, Shuping Wang, Chen Luo, Qiyu Jin, Michael Kwok-Po Ng

Local patch matching is to find similar patches in a large neighborhood which can alleviate noise effect, but the number of patches may be insufficient.

Edge Adaptive Hybrid Regularization Model For Image Deblurring

no code implementations20 Nov 2020 Tingting Zhang, Jie Chen, Caiying Wu, Zhifei He, Tieyong Zeng, Qiyu Jin

In the proposed model, it detects the edges and then spatially adjusts the parameters of Tikhonov and TV regularization terms for each pixel according to the edge information.

A Review of an Old Dilemma: Demosaicking First, or Denoising First?

no code implementations24 Apr 2020 Qiyu Jin, Gabriele Facciolo, Jean-Michel Morel

In this paper, we review the main variants of these strategies and carry-out an extensive evaluation to find the best way to reconstruct full color images from a noisy mosaic.
