[jitter] Re: I know this has been asked a thousand times but....

As it happens my project includes reactivision so I'm aware of the principles behind how that particular system works.

The system I want would be very different - I want to be able to draw a free hand square into an LCD and have my system be able to distinguish between a square and a triangle for example - not find shapes in an image.

More research has told me that perhaps what I need to research is more aligned to sketch recognition rather than image analysis and I have since found an interesting paper that I am looking into - In case anyone else is interested in this subject:

If I get something working I'll post a patch up - I'm sure there are others out there trying to do the same sort of thing.

In the mean time if anyone has any experience in this area and wishes to share knowledge it would be greatly appreciated.

Cheers

Andy
