Multimarginal Wasserstein Barycenter for Stain Normalization and Augmentation
Saad Nadeem, Travis Hollmann, Allen Tannenbaum
Variations in hematoxylin and eosin (H&E) stained images (due to clinical lab protocols, scanners, etc) directly impact the quality and accuracy of clinical diagnosis, and hence it…
Generalizable Cone Beam CT Esophagus Segmentation Using Physics-Based Data Augmentation
Sadegh R Alam, Tianfang Li, Pengpeng Zhang +2
Automated segmentation of esophagus is critical in image guided/adaptive radiotherapy of lung cancer to minimize radiation-induced toxicities such as acute esophagitis. We develope…
Fisher-Rao Regularized Transport Analysis of the Glymphatic System and Waste Drainage
Rena Elkin, Saad Nadeem, Hedok Lee +2
In this work, a unified representation of all the time-varying dynamics is accomplished with a Lagrangian framework for analyzing Fisher-Rao regularized dynamical optimal mass tran…
LMap: Shape-Preserving Local Mappings for Biomedical Visualization
Saad Nadeem, Xianfeng Gu, Arie Kaufman
Visualization of medical organs and biological structures is a challenging task because of their complex geometry and the resultant occlusions. Global spherical and planar mapping…
Spherical Parameterization Balancing Angle and Area Distortions
Saad Nadeem, Zhengyu Su, Wei Zeng +2
This work presents a novel framework for spherical mesh parameterization. An efficient angle-preserving spherical parameterization algorithm is introduced, which is based on dynami…
C2A: Crowd Consensus Analytics for Virtual Colonoscopy
Ji Hwan Park, Saad Nadeem, Seyedkoosha Mirhosseini +1
We present a medical crowdsourcing visual analytics platform called C{}A to visualize, classify and filter crowdsourced clinical data. More specifically, CA is used to buil…
