Abstract: A robust incremental-quaternion-based algorithm is proposed in this paper to estimate the angle and the axis of a single-axis rotation whose rotation axis is invisible or inaccessible. We ...

Brazil's Lula squares up to Trump, measles cases hit a 33-year high, and more Length: Long Speed: 1.0x If you’re the kind of person who gets a lot done, you’re grateful for every one of the 86,400 ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

A trio of physicists from Princeton University, CIT's Jet Propulsion Laboratory and Spectral Sensor Solutions, all in the U.S., is proposing the possibility of generating electricity using energy from ...

Spiral galaxies imaged by JWST that rotate in the same direction relative to the Milky Way (red) and in the opposite direction relative to the Milky Way (blue). The number of galaxies rotating in the ...

If you have data gathered in one coordinate system and want to express them in terms of a different coordinate system, you probably would use a translation vector and a rotation matrix. You can, ...

Abstract: This paper presents two recursive quaternion filters for single-frame attitude determination from vector measurements. In the first filter, the estimate is sequentially projected on ...

At this point, we’re used to AI-powered image tools that instantly pull off previously high-effort edits, like filling in the missing bits of a scene or erasing unwanted parts of a photo without ...
