Zachary L. Newman,Vincent Maurice,Tara E. Drake,Jordan R. Stone,Travis C. Briles,Daryl T. Spencer,Connor Fredrick,Qing Li,Daron A. Westly,B. R. Ilic,Boqiang Shen,Myoung-Gyun Suh,Ki Youl Yang,Cort Johnson,David M. S. Johnson,Leo W. Hollberg,Kerry J. Vahala,Kartik Srinivasan,Scott A. Diddams,John Kitching,Scott B. Papp,Matthew T.

TL;DR: In this paper, a semiconductor laser is stabilized to an optical transition in a microfabricated rubidium vapor cell, and a pair of interlocked Kerr-microresonator frequency combs provide fully coherent optical division of the clock laser to generate an electronic 22 GHz clock signal with a fractional frequency instability of one part in 1013.

SegICP: Integrated Deep Semantic Segmentation and Pose Estimation
Jay Ming Wong,Vincent Kee,Tiffany Le,Syler Wagner,Gian Luca Mariottini,Abraham Schneider,Lei Hamilton,Rahul Chipalkatty,Mitchell Hebert,David M. S. Johnson,Jimmy Wu,Bolei Zhou,Antonio Torralba +12 more
TL;DR: SegICP couples convolutional neural networks and multi-hypothesis point cloud registration to achieve both robust pixel-wise semantic segmentation as well as accurate and real-time 6-DOF pose estimation for relevant objects.

Real-Time Object Pose Estimation with Pose Interpreter Networks
Jimmy Wu,Bolei Zhou,R. Russell,Vincent Kee,Syler Wagner,Mitchell Hebert,Antonio Torralba,David M. S. Johnson +7 more
TL;DR: This work introduces pose interpreter networks for 6-DoF object pose estimation and shows that when combined with a segmentation model trained on RGB images, this synthetically trained pose interpreter network is able to generalize to real data.
