Real-Time Head Pose Tracking with Online Face Template Reconstruction.

IEEE transactions on pattern analysis and machine intelligence

Li S, Ngan KN, Paramesran R, Sheng L.
PMID: 26584487
IEEE Trans Pattern Anal Mach Intell. 2016 Sep;38(9):1922-8. doi: 10.1109/TPAMI.2015.2500221. Epub 2015 Nov 12.

We propose a real-time method to accurately track the human head pose in the 3-dimensional (3D) world. Using a RGB-Depth camera, a face template is reconstructed by fitting a 3D morphable face model, and the head pose is determined...

Angew Chem Int Ed Engl. 2017 Nov 06;56(45):13962-13967. doi: 10.1002/anie.201708238. Epub 2017 Oct 04.

Knowing the thermodynamic state of complex mixtures-liquid, gas, supercritical or two-phase-is essential to industrial chemical processes. Traditionally, phase diagrams are compiled piecemeal from individual measurements in a pressure-volume-temperature cell performed in series, where each point is subject to a...

From 1-Sulfonyl-4-aryl-1,2,3-triazoles to 1-Allenyl-5-aryl-1,2,3-triazoles.

An efficient and highly regioselective synthesis of 1-allenyl-5-aryl-1,2,3-triazoles from 1-sulfonyl-4-aryl-1,2,3-triazoles is disclosed. 1-Sulfonyl-4-aryl-1,2,3-triazoles reacted with propargylic alcohols in the presence of trifluoroboron etherate to furnish 1-allenyl-5-aryl-1,2,3-triazoles. When secondary alcohols were used as substrate, the outcome of the reaction was...
