A New Scheme for Robust Gradient Vector Estimation in Color Images


Gradient estimators are mostly designed to yield accurate and robust estimates of the gradient magnitude, not the gradient direction. This paper proposes a method for the accurate and robust estimation of both the gradient magnitude and direction. It robustly estimates the gradient in the <i>x</i>- and <i>y</i>-directions. The robustness against noise is… (More)
