Abstract: This paper investigates a fundamental yet underexplored issue in Salient Object Detection (SOD): the size-invariant property for evaluation protocols, particularly in scenarios when multiple ...

Abstract: Remote sensing image captioning is the task of automatically generating descriptive texts for remotely sensed scenes and objects. A common shortcoming of existing methods is the inadequate ...

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 ...

The Avi Loeb Podcast recently featured a discussion centered on new observational results related to the interstellar object known as 3I/ATLAS. The episode followed the release of two new scientific ...

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, ...
