A New Digital Face Makeup Method Abstract: This paper proposes a new method for the application of makeup on the eyes, face, and lips based on several makeup examples. We created two Gaussian weight maps to generate the effect of natural skin makeup. Due to our Gaussian weight map in blending process, our makeup results […]
Exploiting Spatial Channel Covariance for Hybrid Precoding in Massive MIMO Systems Abstract: We propose a new hybrid precoding technique for massive multi-input multi-output (MIMO) systems using spatial channel covariance matrices in the analog precoder design. Applying a regularized zero-forcing precoder for the baseband precoding matrix, we find an unconstrained analog precoder that maximizes signal-to-leakage-plus-noise ratio […]
