Generating Synthetic X-ray Images of a Person from the Surface Geometry

no code implementations CVPR 2018 Brian Teixeira, Vivek Singh, Terrence Chen, Kai Ma, Birgi Tamersoy, Yifan Wu, Elena Balashova, Dorin Comaniciu

Furthermore, the synthetic X-ray image is parametrized and can be manipulated by adjusting a set of body markers which are also generated during the X-ray image prediction.

Structure-Aware Shape Synthesis

no code implementations4 Aug 2018 Elena Balashova, Vivek Singh, Jiangping Wang, Brian Teixeira, Terrence Chen, Thomas Funkhouser

We propose a new procedure to guide training of a data-driven shape generative model using a structure-aware loss function.

Repetitive Motion Estimation Network: Recover cardiac and respiratory signal from thoracic imaging

no code implementations8 Nov 2018 Xiaoxiao Li, Vivek Singh, Yifan Wu, Klaus Kirchberg, James Duncan, Ankur Kapoor

Tracking organ motion is important in image-guided interventions, but motion annotations are not always easily available.

Deep Decision Network for Multi-Class Image Classification

no code implementations CVPR 2016 Venkatesh N. Murthy, Vivek Singh, Terrence Chen, R. Manmatha, Dorin Comaniciu

During the learning phase, starting from the root network node, DDN automatically builds a network that splits the data into disjoint clusters of classes which would be handled by the subsequent expert networks.

Automated CT Lung Cancer Screening Workflow using 3D Camera

no code implementations27 Sep 2023 Brian Teixeira, Vivek Singh, Birgi Tamersoy, Andreas Prokein, Ankur Kapoor

We demonstrate the effectiveness of our method on a testing set of 110 pairs of depth data and CT scan, resulting in an average error of 5mm in estimating the isocenter, 13mm in determining the scan range, 10mm and 16mm in estimating the AP and lateral WED respectively.

EEG-Based Reaction Time Prediction with Fuzzy Common Spatial Patterns and Phase Cohesion using Deep Autoencoder Based Data Fusion

no code implementations1 Dec 2023 Vivek Singh, Tharun Kumar Reddy

Drowsiness state of a driver is a topic of extensive discussion due to its significant role in causing traffic accidents.

EEG regression

Cardiac ultrasound simulation for autonomous ultrasound navigation

no code implementations9 Feb 2024 Abdoul Aziz Amadou, Laura Peralta, Paul Dryburgh, Paul Klein, Kaloian Petkov, Richard James Housden, Vivek Singh, Rui Liao, Young-Ho Kim, Florin Christian Ghesu, Tommaso Mansi, Ronak Rajani, Alistair Young, Kawal Rhode

However, the image quality varies with operator skills as acquiring and interpreting ultrasound images requires extensive training due to the imaging artefacts, the range of acquisition parameters and the variability of patient anatomies.

Image Generation

Feature boosting with efficient attention for scene parsing

no code implementations29 Feb 2024 Vivek Singh, Shailza Sharma, Fabio Cuzzolin

This paper presents a novel feature-boosting network that gathers spatial context from multiple levels of feature extraction and computes the attention weights for each level of representation to generate the final class labels.

Toward Safe Evolution of Artificial Intelligence (AI) based Conversational Agents to Support Adolescent Mental and Sexual Health Knowledge Discovery

no code implementations3 Apr 2024 Jinkyung Park, Vivek Singh, Pamela Wisniewski

Following the recent release of various Artificial Intelligence (AI) based Conversation Agents (CAs), adolescents are increasingly using CAs for interactive knowledge discovery on sensitive topics, including mental and sexual health topics.

Leveraging Large Language Models (LLMs) to Support Collaborative Human-AI Online Risk Data Annotation

no code implementations11 Apr 2024 Jinkyung Park, Pamela Wisniewski, Vivek Singh

Therefore, we provide some of the early benefits and challenges of using LLMs-based tools for risk annotation and suggest future directions for the HCI research community to leverage LLMs as research tools to facilitate human-AI collaboration in contextualized online data annotation.
