    High-Resolution Source Localization Algorithm Based on the Conjugate Gradient

    This paper proposes a new algorithm for the direction of arrival (DOA) estimation of P radiating sources. Unlike the classical subspace-based methods, it does not resort to the eigendecomposition of the covarianc...

    Better Flow Estimation from Color Images

    One of the difficulties in estimating optical flow is bias. Correcting the bias using the classical techniques is very difficult. The reason is that knowledge of the error statistics is required, which usually...
