Beyond Photometric Loss for Self-Supervised Ego-Motion Estimation [PDF]

IEEE International Conference on Robotics and Automation, 2019
Accurate relative pose is one of the key components in visual odometry (VO) and simultaneous localization and mapping (SLAM). Recently, the self-supervised learning framework that jointly optimizes the relative pose and target image depth has attracted ...

More Efficient and Reliable: Identifying RRab Stars with Blazhko Effect by Deep Convolutional Neural Network

Universe
The physical origin of the Blazhko effect (BL), a phenomenon of a single or multiple periodic modulation(s) of the light curve, is under debate. Efficiently identifying and characterizing the BL is essential in understanding its origins and accounting ...
