Improved Covariance Matrix Estimator using Shrinkage Transformation and Random Matrix Theory
Samruddhi Deshmukh, Amartansh Dubey
One of the major challenges in multivariate analysis is the estimation of population covariance matrix from sample covariance matrix (SCM). Most recent covariance matrix estimators…
Robust and Real Time Detection of Curvy Lanes (Curves) with Desired Slopes for Driving Assistance and Autonomous Vehicles
Amartansh Dubey, K. M. Bhurchandi
One of the biggest reasons for road accidents is curvy lanes and blind turns. Even one of the biggest hurdles for new autonomous vehicles is to detect curvy lanes, multiple lanes a…
