Projects
Automotive Research
Autonomous Navigation in self-driving cars
ELMs and RL play fundamental roles in modern autonomous driving systems. This research introduces light-weight and efficient ELM and DRL models for end-to-end autonomous navigation in complex scenarios based on camera as the only sensor.
Visual SLAM (simultaneous localization & mapping)
This research focuses on the development and deployment of high-definition localization and adaptive mapping in real time for enhanced autonomous navigation in GPS-degraded and visually ambiguous environments. We incorporate semantic understanding into SLAM models for accurate mapping of highly dynamic environments.
Scene Perception models in self driving cars
This project aims to enhance real-time multi-object detection capabilities for self-driving cars, specifically operating effectively in various adverse weather conditions (e.g., rain, fog, and snow), which can significantly impair the accuracy and reliability of object detection systems in autonomous vehicles.
Driver Attention
This research focuses on driver's visual and manual distraction. Capturing driver’s video through camera, attention level is analyzed. Key objective is to design reliable and compact models to facilitate gaze estimation and action recognition in DMS.
Driver Impairment
This research focuses on addressing driver fatigue and the influence of alcohol and drugs on driving behavior. Through innovative solutions and advanced technologies, we aim to uncover key biomarkers and behavioral indicators for real-time impairment monitoring and contributing to a safer driving.
Driver State
This project is dedicated to understanding the dynamic assessment of driver's emotion, well-being and cognitive workload and enhance the overall driving experience. The objective is to shape the future of transportation with a focus on holistic driver well-being and mental resilience.
Adaptive Handover System
An adaptive handover system is a novel idea aimed at optimizing the control transfer between driver and automated system. This requires dynamically adjusting a TOR based on a real-time analysis of both driver's state and road/traffic conditions to perform the most appropriate action. This could mean altering a request's modality, timing, or location. Such an adaptive approach promises to enhance safety by mitigating the risks associated with a handover system.
Agriculture Research
Vision based growth monitoring
Leveraging AI and computer vision technologies, we are dedicated to transforming the assessment of the growth dynamics of crops and plants. Our vision-based approach enables precise and real-time monitoring of key indicators, contributing to enhanced crop management practices. From tracking plant development to identifying potential stress factors, our research aims to empower farmers with actionable insights for optimized yields and sustainable farming.
Clinical Research
AI-Based Musical Intervention to Improve Emotion
Mental disorders have a significant influence on the daily activities of Canadians. Musical intervention can provide a non-invasive treatment through changing emotional state and creating positive mood. The main objective of this project is a long-term solution for musical intervention through an optimized machine learning framework for a real-time emotion recognition and musical intervention system integrated in an empathetic speaker. During music play, the emotional influence will be detected from EEG and the music database will be customized.
AI-based classification of children’s speech-sound development
Speech and language sampling are key components of a Speech-Language Pathologist’s assessment of the presence/absence of a disorder. The main objective of this project is to develop a novel LLM-based framework to process and analyze children's speech data and recognize common developmental patterns and errors.
AI-based application for monitoring developmental outcomes in children who have hearing loss
Developing an AI-based digital application for early hearing detection and intervention that aims to address current PedAMP administration limitations by streamlining data collection, improving accuracy, and enhancing data accessibility for decision-making and program evaluation.
