Proceedings ArticleDOI
MPEG-4 outer-inner lip FAP interpolation
TL;DR: A more realistic talking animation that provides more visual information for speech reading can be achieved as a result of interpolation and realistic animation that can be accomplished at very low bit rates.
Proceedings Article
Restoration of the cantilever bowing distortion in Atomic Force Microscopy images
TL;DR: An automated algorithm to flatten lines from AFM images is presented and the proposed method is compared to an entropy based MRI inhomogeniety correction method, demonstrating the effectiveness of the proposed algorithm in increasing the resolution of the surface topography.
Proceedings ArticleDOI
Properties of different estimates of the regularizing parameter for the least-squares image restoration problem
TL;DR: In this paper, the authors propose a regularizing parameter which trades fidelity to the data with smoothness of the restored image for most problems of interest, but the choice of the regularising parameter is not known a priori.
Journal ArticleDOI
DeepCOVID-Fuse: A Multi-Modality Deep Learning Model Fusing Chest X-rays and Clinical Variables to Predict COVID-19 Risk Levels
TL;DR: DeepCOVID-Fuse as discussed by the authors is a deep learning fusion model that predicts risk levels in patients with confirmed COVID-19 by combining chest radiographs (CXRs) and clinical variables.
