A GPU-Accelerated Light-field Super-resolution Framework Based on Mixed Noise Model and Weighted Regularization
Trung-Hieu Tran, Kaicong Sun, Sven Simon
This paper presents a GPU-accelerated computational framework for reconstructing high resolution (HR) LF images under a mixed Gaussian-Impulse noise condition. The main focus is on…
Multi-Material Blind Beam Hardening Correction Based on Non-Linearity Adjustment of Projections
Ammar Alsaffar, Kaicong Sun, Sven Simon
Beam hardening (BH) is one of the major artifacts that severely reduces the quality of Computed Tomography (CT) imaging. In a polychromatic X-ray beam, since low-energy photons are…
Computational Scatter Correction for High-Resolution Flat-Panel CT Based on a Fast Monte Carlo Photon Transport Model
Ammar Alsaffar, Steffen Kieß, Kaicong Sun +1
In computed tomography (CT) reconstruction, scattering causes server quality degradation of the reconstructed CT images by introducing streaks and cupping artifacts which reduce th…
3DVSR: 3D EPI Volume-based Approach for Angular and Spatial Light field Image Super-resolution
Trung-Hieu Tran, Jan Berberich, Sven Simon
Light field (LF) imaging, which captures both spatial and angular information of a scene, is undoubtedly beneficial to numerous applications. Although various techniques have been…
A Resolution Enhancement Plug-in for Deformable Registration of Medical Images
Kaicong Sun, Sven Simon
Image registration is a fundamental task for medical imaging. Resampling of the intensity values is required during registration and better spatial resolution with finer and sharpe…
FL-MISR: Fast Large-Scale Multi-Image Super-Resolution for Computed Tomography Based on Multi-GPU Acceleration
Kaicong Sun, Trung-Hieu Tran, Jajnabalkya Guhathakurta +1
Multi-image super-resolution (MISR) usually outperforms single-image super-resolution (SISR) under a proper inter-image alignment by explicitly exploiting the inter-image correlati…
Bilateral Spectrum Weighted Total Variation for Noisy-Image Super-Resolution and Image Denoising
Kaicong Sun, Sven Simon
In this paper, we propose a regularization technique for noisy-image super-resolution and image denoising. Total variation (TV) regularization is adopted in many image processing a…
FDRN: A Fast Deformable Registration Network for Medical Images
Kaicong Sun, Sven Simon
Deformable image registration is a fundamental task in medical imaging. Due to the large computational complexity of deformable registration of volumetric images, conventional iter…
