Face alignment is an important process in facial analysis. Cascaded linear regression approaches have shown the capability to achieve the state-of-the-art accuracy on numerous face alignment datasets. However, most of these approaches only learn to map coordinate offsets of the key points from image features. This regression strategy can be easily trapped in local optima. We propose a novel regression...
By using the three-dimensional finite-difference time-domain (FDTD) algorithm, we investigated the optimal structure parameters of pyramidal arrays used for millimeter-wave radiometer calibration. The arrays are constructed with a periodically arranged metallic pyramids which are coated with absorbing materials. In considering the difficulties in manufacturing the sharp tips of the pyramids, we investigated...
Ultra-Wideband (UWB) communication has attracted more attentions due to its advantages in short range applications. As one of the key techniques in UWB systems, many pulse shaping methods have been proposed. The semi-definite programming (SDP) based pulse shaping method can obtain the pulse with highest power efficiency by far. However, an accurate timing of 40 ps is required, and such requirement...
