CT and MRI Fusion with Anisotropic Guided Filtering

Yuping Huang, Weisheng Li, Guofen Wang, Xiaoyu Qiao, Huanyu Chen

ICASSP 2024accepted

The combination of CT and MRI can provide more accurate images of lesions, yielding a significantly higher diagnostic value compared to single-modality pathological images. However, in CT-MRI fusion, preserving the gray-scale distribution of the source image while avoiding ‘detail halos’ poses a cha…

Window-Based Convolutional Sparse Coding: Towards A Unified Framework

Lijian Yang, Jian-Xun Mi, Guofen Wang, Weisheng Li

ICASSP 2024accepted

Sparse Coding (SC) and Convolution Sparse Coding (CSC) are two widely studied sparse methods in computer vision and signal processing. SC encodes the image patches independently, however fails to utilize the correlation among them. CSC adopts a convolution operator to connect the overlapping patches…
