Submerse: Visualizing Storm Surge Flooding Simulations in Immersive Display Ecologies
Saeed Boorboor, Yoonsang Kim, Ping Hu +3
We present Submerse, an end-to-end framework for visualizing flooding scenarios on large and immersive display ecologies. Specifically, we reconstruct a surface mesh from input flo…
CLTS-GAN: Color-Lighting-Texture-Specular Reflection Augmentation for Colonoscopy
Shawn Mathew, Saad Nadeem, Arie Kaufman
Automated analysis of optical colonoscopy (OC) video frames (to assist endoscopists during OC) is challenging due to variations in color, lighting, texture, and specular reflection…
Geometry-Aware Planar Embedding of Treelike Structures
Ping Hu, Saeed Boorboor, Joseph Marino +1
The growing complexity of spatial and structural information in 3D data makes data inspection and visualization a challenging task. We describe a method to create a planar embeddin…
NeuRegenerate: A Framework for Visualizing Neurodegeneration
Saeed Boorboor, Shawn Mathew, Mala Ananth +3
Recent advances in high-resolution microscopy have allowed scientists to better understand the underlying brain connectivity. However, due to the limitation that biological specime…
COVID-view: Diagnosis of COVID-19 using Chest CT
Shreeraj Jadhav, Gaofeng Deng, Marlene Zawin +1
Significant work has been done towards deep learning (DL) models for automatic lung and lesion segmentation and classification of COVID-19 on chest CT data. However, comprehensive…
FoldIt: Haustral Folds Detection and Segmentation in Colonoscopy Videos
Shawn Mathew, Saad Nadeem, Arie Kaufman
Haustral folds are colon wall protrusions implicated for high polyp miss rate during optical colonoscopy procedures. If segmented accurately, haustral folds can allow for better es…
Visualizing Missing Surfaces In Colonoscopy Videos using Shared Latent Space Representations
Shawn Mathew, Saad Nadeem, Arie Kaufman
Optical colonoscopy (OC), the most prevalent colon cancer screening tool, has a high miss rate due to a number of factors, including the geometry of the colon (haustral fold and sh…
Augmenting Colonoscopy using Extended and Directional CycleGAN for Lossy Image Translation
Shawn Mathew, Saad Nadeem, Sruti Kumari +1
Colorectal cancer screening modalities, such as optical colonoscopy (OC) and virtual colonoscopy (VC), are critical for diagnosing and ultimately removing polyps (precursors of col…
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…
Visualization Framework for Colonoscopy Videos
Saad Nadeem, Arie Kaufman
We present a visualization framework for annotating and comparing colonoscopy videos, where these annotations can then be used for semi-automatic report generation at the end of th…
Corresponding Supine and Prone Colon Visualization Using Eigenfunction Analysis and Fold Modeling
Saad Nadeem, Joseph Marino, Xianfeng Gu +1
We present a method for registration and visualization of corresponding supine and prone virtual colonoscopy scans based on eigenfunction analysis and fold modeling. In virtual col…
FeatureLego: Volume Exploration Using Exhaustive Clustering of Super-Voxels
Shreeraj Jadhav, Saad Nadeem, Arie Kaufman
We present a volume exploration framework, FeatureLego, that uses a novel voxel clustering approach for efficient selection of semantic features. We partition the input volume into…
Radiative Transport Based Flame Volume Reconstruction from Videos
Liang Shen, Dengming Zhu, Saad Nadeem +2
We introduce a novel approach for flame volume reconstruction from videos using inexpensive charge-coupled device (CCD) consumer cameras. The approach includes an economical data c…
Crowd-Assisted Polyp Annotation of Virtual Colonoscopy Videos
Ji Hwan Park, Saad Nadeem, Joseph Marino +3
Virtual colonoscopy (VC) allows a radiologist to navigate through a 3D colon model reconstructed from a computed tomography scan of the abdomen, looking for polyps, the precursors…
Crowdsourcing Lung Nodules Detection and Annotation
Saeed Boorboor, Saad Nadeem, Ji Hwan Park +2
We present crowdsourcing as an additional modality to aid radiologists in the diagnosis of lung cancer from clinical chest computed tomography (CT) scans. More specifically, a comp…
Eccentricity Effects on Blur and Depth Perception
Qi Sun, Fu-Chung Huang, Li-Yi Wei +3
Foveation and focus cue are the two most discussed topics on vision in designing near-eye displays. Foveation reduces rendering load by omitting spatial details in the content that…
Depth Reconstruction and Computer-Aided Polyp Detection in Optical Colonoscopy Video Frames
Saad Nadeem, Arie Kaufman
