Worked with AirSim simulator to generate synthetic data to test object detection models on new environments.
Used a physics-based particle simulator in order to augment clear weather conditions to rain and fog of varying intensities.
Achieved around 55% improvement in mAP score after training YOLOv5 on augmented weather data.
Implemented state-of-the-art monocular depth estimation and instance segmentation algorithms using PyTorch.
Incorporated scale and shift factors to arrive at quantitative estimates of depth from the estimated disparity map.
Used Delaunay Triangulation and projection-based volume estimation to develop a volume estimation application.
The % error averages around 20% for regular objects (such as ball) and 40% for irregular objects (such as heaps).
Devised a theoretically rigorous criterion based on hypothesis testing to estimate order of the MIMO model.
Developed a novel iterative algorithm based on Principal Component Analysis in MATLAB that estimates measurement error variances and state space model parameters in the presence of process and measurement noises.
Simulation experiments indicate that the proposed algorithm provides consistent estimates of all parameters.
