Introduction

Object recognition is one of the hottest areas in computer vision. Finding and identifying objects in an image is fundamental to facial recognition, object tracking in videos, object matching and many other applications. To achieve object recognition (from images), one first must be able to extract distinct features of the image, then correctly identify the object of interest from these key features. Our group explored three different algorithms. The first, Scale-Invariant Feature Transform, was a method to obtain the distinct features of the image while the other two, Hough Transform and Moment of Inertia, were pattern recognizing algorithms.

Motivation

We wanted to simulate a user being given a sheet of paper with squares and other shapes on it. The user would tell us how many squares appeared in the image. Because we were highly interested in the field of object recognition we decided to implement two systems and compare the results. Both systems used Scale-Invariant Feature Transform to obtain feature points. The first system then passed those results into the Hough Transform. The second system used the feature points to implement a formula involving the properties of the Moment of Inertia.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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?
Damian
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.

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.
