Abstract: Recent advances in simultaneous localization and mapping (SLAM) systems have significantly enhanced the process of creating 3D digital replicas of real-world environments. Numerous ...

Abstract: This letter studies a new open-set problem, the open-vocabulary category-level object pose and size estimation. Given human text descriptions of arbitrary novel object categories, the robot ...

The Black Knight story didn’t begin as a claim of alien technology. It began as an object that didn’t fit existing categories. Early observations, signals, and images were difficult to reconcile with ...

Remarkably, human brains have the ability to accurately perceive and process the real-world size of objects, despite vast differences in distance and perspective. While previous studies have delved ...

It’s a universal fact that as any 3D object, from a Platonic sphere to a cell to an elephant, grows outward in all directions, its total surface area will increase more slowly than the space it ...

A Harvard scientist had expressed alarm as an object the size of Manhattan continues to glide through our solar system, releasing a metallic vapour with a baffling composition. Since interstellar ...

The Manhattan-size interstellar object 3I/ATLAS will buzz past Mars this week — making its closest pass to any planet on its route as scientists are rushing to coordinate craft to observe the ...

New data from the International Gemini Observatory revealed the object has grown in its estimated size, with it now weighing more than 33 billion tons. Avi Loeb, a Harvard University astrophysicist, ...

Don’t look now folks, but 2025 has flown by and we are now in the last quarter of the year. It has not been a year without disaster and despair, but if you are reading this the good news is that you ...
