Scientists invent new sensing eye mask

From the team that invented physiology-sensing pajamas at the University of Massachusetts Amherst, now comes a new, lightweight eye mask that can unobtrusively capture pulse, eye movement and sleep signals, for example, when ...

Researchers at IceCube detect record energy neutrinos

(Phys.org) —Researchers at the Antarctic research station IceCube are reporting that they've detected the highest ever energy neutrinos ever observed. In their paper they've uploaded to the preprint server arXiv, the team ...

Researchers develop a way to remotely detect landslides

(Phys.org) —Seismologists from Columbia University in New York have developed a way to detect landslides using a combination of seismic data and data collected from satellite images. The technique can be used, the team ...

Data from Insight reveals size of Mars's core

An international team of researchers studying seismic data collected by NASA's Insight spacecraft has used the data to calculate the size of Mars' core. The group plans to discuss their findings at this year's Lunar and Planetary ...

Sensor fusion

Sensor fusion is the combining of sensory data or data derived from sensory data from disparate sources such that the resulting information is in some sense better than would be possible when these sources were used individually. The term better in that case can mean more accurate, more complete, or more dependable, or refer to the result of an emerging view, such as stereoscopic vision (calculation of depth information by combining two-dimensional images from two cameras at slightly different viewpoints).

The data sources for a fusion process are not specified to originate from identical sensors. One can distinguish direct fusion, indirect fusion and fusion of the outputs of the former two. Direct fusion is the fusion of sensor data from a set of heterogeneous or homogeneous sensors, soft sensors, and history values of sensor data, while indirect fusion uses information sources like a priori knowledge about the environment and human input.

Sensor fusion is also known as (multi-sensor) Data fusion and is a subset of information fusion.
