This paper is concerned of the loop closure detection problem, which is one of the most critical parts for visual Simultaneous Localization and Mapping (SLAM) systems. Most of state-of-the-art methods use hand-crafted features and bag-of-visual-words (BoVW) to tackle this problem. Recent development in deep learning indicates that CNN features significantly outperform hand-crafted features for image...
Pin accessibility influences the routability of a design at the stage of block/chip assembling. The estimation model for pin accessibility in previous researches counts the total number of intersections between each pin and M2 routing tracks. It does not consider the variation of pin accessibility as the spacing between a pin and its neighboring pins and metal wires changes. Besides, it cannot properly...
A Lunar Penetrating Radar (LPR) based on time domain Ultra Wide Band (UWB) technique is currently within the scope of China's Chang-E 3 (CE-3) lunar mission, with the purpose of studying the subsurface structure of the Moon. Exploring the UWB microwave radiation and transfer properties of lunar regolith and establishing a reasonable inverse model are essential for the estimation of the thickness of...
