Our goal is to create intelligent motion detection for compressed sensing.

Can random noise yield specific information?

The novel challenge with using random basis projections for intelligent motion detection is that there is nospatial information about the image or movie in the compressed sensing data. Traditional pixel-based cameras provide a graph oflight intensity over position and, logically, most pixel-based detection approaches use the information about where the motionoccurs to help classify it. [1] The CS data provides us not withintensity at a point, but with the similarity (inner product) between the original pixel image and a selection of basis elementscomposed of random noise spread throughout the image plane. Intelligent detection for CS, therefore, must use approachesradically different from detection used on conventional video.

Simplicity for low power

A key feature of CS systems is the potential for extremely low power consumption. To keep the overall power ofthe system low, any computations we perform must be low power as well. For practical application, the algorithms chosen must be simple to compute.

Investigation goals

Working in a very new field, we began our project with the open-ended goal of researching what types ofmotion can be detected using compressed sensing and of implementing at least one such measurement. After much deliberation and trial,we chose to implement speed detection, specifically calculating the speed of a known object along the direction of motion. (Differentshapes complicate the problem, as we will discuss.) Looking ahead to more sophisticated detection, we also wanted an extensiblesystem to use the results of several relevant calculations to automatically characterize motion.

Though beyond the scope of our investigation, our motivation is a camera running our intelligent detection systemcapable of determining if a desired type of motion is observed. We pursue algorithms which could be implemented in real time at thedata collection point.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
