[scilab-Users] real time image processing

[Mike Page]

Hi Alain,

I have successfully used Scilab with a real-time system, though I have not
used Scicos.  I also use Scilab to prototype my algorithms before developing
the "real" system.

Scilab has a built-in system for compiling your own C code into Scilab
functions, but I don't use it.  I just use MS Visual C++ to write the C code
and build it as a DLL.  Then it's quite easy to declare the entry points in
Scilab and call the C functions from within your Scilab code.  There is help
available in the documentation, but it is a bit fragmented and also not all
relevant to the latest version.

Be aware that Scilab can be quite slow, depending on what you are doing, and
it may not be able to keep up with your hardware.  However, I am doing some
quite intensive signal processing and my code runs with a 250ms loop time.

When you get to the stage where you are integrating your C code and Scilab,
just post any specific questions here.  There are lots of people who will
help you.

Good luck,
Mike.

Subject: [scilab-Users] real time image processing


Hello!

I need to real time process a sonar image flow. The goal is to detect
object and follow them, as the sonar is moving.
I'm familiar to scilab, and I'd like to use it to prototype the process,
and if possible, generate C code for the real time software.
I've never use xcos, but I'd like to.
As my process is discrete, do you think xcos is adapted for image
processing? Is it easy to generate C code and then link it to the rest
of my application?

Thanks.

Alain
