Gaze Estimation Approach Using Deep Differential Residual Network

no code implementations8 Aug 2022 Longzhao Huang, Yujie Li, Xu Wang, Haoyu Wang, Ahmed Bouridane, Ahmad Chaddad

We propose a differential residual model (DRNet) combined with a new loss function to make use of the difference information of two eye images.

Deep radiomic signature with immune cell markers predicts the survival of glioma patients

no code implementations9 Jun 2022 Ahmad Chaddad, Paul Daniel Mingli Zhang, Saima Rathore, Paul Sargos, Christian Desrosiers, Tamim Niazi

These results demonstrate the usefulness of proposed DRFs as non-invasive biomarker for predicting treatment response in patients with brain tumors.

Deep Radiomic Analysis for Predicting Coronavirus Disease 2019 in Computerized Tomography and X-ray Images

no code implementations4 Jun 2022 Ahmad Chaddad, Lama Hassan, Christian Desrosiers

Our results suggest that the proposed GMM-CNN features could improve the prediction of COVID-19 in chest computed tomography and X-ray scans.

Modeling of Textures to Predict Immune Cell Status and Survival of Brain Tumour Patients

no code implementations4 Jun 2022 Ahmad Chaddad, Mingli Zhang, Lama Hassan, Tamim Niazi

Combined the immune markers with DRFs and clinical variables, Kaplan-Meier estimator and Log-rank test achieved the most significant difference between predicted groups of patients (short-term versus long-term survival) with p\,=\, 4. 31$\times$10$^{-7}$ compared to p\,=\, 0. 03 for Immune cell markers, p\,=\, 0. 07 for clinical variables , and p\,=\, 1. 45$\times$10$^{-5}$ for DRFs.
