Design and characteristic analysis of hybrid OFD–LFM–PC waveforms in the MIMO radar
In this study, a new set of hybrid orthogonal frequency division–linear frequency modulation–phase coded (OFD–LFM–PC) waveforms are proposed to improve the detection performance of multiple-input-multiple-output (MIMO) radars.

Human Pose Estimation by Exploiting Spatial and Temporal Constraints in Body-Part Configurations
We present an algorithm for estimating a sequence of articulated upper-body human pose in unconstrained videos. Most previous work often fails to locate forearms in those video scenes suffering from illumination varieties, background clutter, camera ...
