I now know a little about convolution and I have the Prewitt and Sobel convolution masks. Fantastic. However, I was unable to implement them in matlab, because unfortunately it seems that I used up todays quota of luck by catching the bus home. Well, actually I missed the 418 and had to hang around for the next one, so I didn't really catch the bus, but never mind. Anyway, matlab goes on about some permission thing, and spews out lots of red writing, which must be bad. So I closed it. I will go up early tomorrow morning (argh I guess it's later this morning now) and have a play.

I will leave you with the link for today; nTAG. Go look at the little flash video things (like this one), they're fantastic! Can you imagine anyone using these things at a conference or something?!
