Re: Image Enhancement

[Dan Burns <kilroi@LGHS.NET>]

I attended a video capture and analysis workshop conducted by Priscilla
Laws at the AAPT meeting in Anaheim last January. It was time well spent.
I have looked at several video analysis software packages and Video Point
(Lenox Software - sold by PASCO) is the best. They probably conduct
seberal workshops a year. I am going to implement this technology in my
AP Physics classes next year. There is a new video capture technology
that allows for direct importing of digital video data from a digital
camcorder (Sony iLink) to a properly equipped PC or Mac with a Firewire
input. This eliminates all the usual video capture headaches.
