TL;DR: The Visual Object Tracking challenge VOT2019 is the seventh annual tracker benchmarking activity organized by the VOT initiative; results of 81 trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in the recent years.

TL;DR: The goal is to advance the state-of-the-art detection algorithms and provide a comprehensive evaluation platform for them and demonstrate that there still remains a large room for improvement for object detection algorithms on drones.

TL;DR: A fully convolutional box head and a supervised edge attention module in mask head and one new IoU prediction branch are proposed to achieve impressive and robust improvement compared to baseline models in instance segmentation.

TL;DR: In this article, a planar dual-frequency power divider based on umbrella-shaped dualmode resonator is presented, which can provide not only dual band, but also direct current (DC) block characteristic and compact size, which fits for microwave intergraded circuit application.

TL;DR: A novel RFID reader antenna for 910–915 MHz is proposed, which mainly consists of three elements rectangular radiation patches and several coplanar parasitic elements and is well suitable for the application in railway RFID circumstance.
