Abstract: Uncrewed aerial vehicle (UAV) object detection is crucial in open-water search and rescue missions. Due to varying perspectives and altitudes of UAV images, the apparent size of objects ...

Abstract: Open-world object detection (OWOD) extends object detection problem to a realistic and dynamic scenario, where a detection model is required to be capable of detecting both known and unknown ...

Explore black hole discovery in astrophysics, from hidden stellar remnants to supermassive giants, and learn how scientists detect these invisible cosmic objects using light and gravitational waves.

A party hat-shaped object spotted on Mars is drawing renewed scrutiny, with some experts suggesting it could be evidence of something major while others offered a trashy explanation for the cone. The ...

Artificial intelligence detectors are increasingly used to check the veracity of content online. We ran more than 1,000 tests and found several strengths and plenty of weaknesses. By Stuart A.

Earnings announcements are one of the few scheduled events that consistently move markets. Prices react not just to the reported numbers, but to how those numbers compare with expectations. A small ...
