yeup i left the SOM image analysis before completing it and may be some time before start this again. just wanted to update about the new short article upon generation5.org. it has been there for quite some time but yet to get links on home page dont know why 
. any way it will act as a good continuation along with the other methods of analysis from the previous blog post, using hough Transforms to find edges or more accurately shapes inside images. any more info and this blog will become a copy so head out to the article to read it yourself
An Introduction to Hough Transforms By James Matthews
