	Hi Dina:

My notes and the .SCE exercises I did in SIVP and IPD are all there in the Google Document folder. I would'nt like to attached them here it will be unnecessary for others, so I sent out to your yahoo email the access to it but don't exactly know if that can work - I suggest you create a gmail account too.

Regards,
Berns B.

	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.

Hi Berns B,

I'm sorry, I missed out your e-mail.It goes to spam folder.Anyway, can I try with the SCE file you said previously? Don't you mind about that?

Another thing is, the Scilab that I have installed can't read the .gif image? is it because that I'm using the SIVP instead of SIP?

Regards,
Dina

	Hi Dina:

Same problem I meet with my students in elective class for physics majors - image file pointing is the first real thing one need to do before even doing any image processing! I'll send you an SCE file later for you to try out next.

Regards,

Berns B.

	Hi:

Try this:
RGB = imread(SCI + '/contrib/sivp/0.5.3-2/images/lena.png');

Hello,

This is my first time using Scilab. And I have no experience at all. I'm

interested to learn Scilab, especially for image processing.

I had installed Scilab 5.3.3 and SIVP 0.5.3 on my Windows XP. My first

attempt is to read and display image of lena.png. And I followed steps

inside tutorial,but failed.Could anyone help me with this. Am I missing

something? How do I know that my installation is working well?

1st attempt:

-->im=imread('lena.png');

                      !--error 999

imread: Can not open file lena.png.

2nd attempt:

-->im=imread('C:\Program

Files\scilab-5.3.3\contrib\SIVP_0.5.3\images\lena.png');

-->imshow(im);

           !--error 999

Bad (1 th) index in hypermatrix extraction.

Thank you.
