Hi Dina:

I have been out for a Christmas holiday with my wife and my classes at USC
(Cebu, Philippines) will not start until next week so I have not gotten
back to you on some of the examples I gave in class for the elective course
I teach there for physics majors.

Will send them to you over the weekend for your exercise (and give me
feedback if you think its too easy, challenging, difficult etc.).

I would suggest work on PNG, BMP and JPG files - when I was part of
developing optical tests systems in my former work we used PNGs for
automotive vision work at the school were kind of used in lossless BMPs and
compressed JPEGS.

You can also try to check your output externally by a canned software like
ImageJ (free) so to match the results of your code. Also, I work with both
SIVP and IPD interchangeably because of the functions available in both of
this programs - and also it depends on what level of machine vision your
working on.

Regards,
Berns B.
