Quick C question

[agabriel at home.tzo.org (Anthony Gabrielson)]

I'm taking a robotics course and at the end of the day the code needs to 
be my own.  I am in fact doing this in Matlab at first and then I'm going 
to convert it to C with Mex wrapper.  Since we are on the subject of image 
processing does anyone know of any good articles for shape recognition by 
chance?

Thanks,
Anthony
