RE: PIV processing

[Sven-Erik Tiberg]

Just a note.

When we made a PIV processing system back in 90-93 se: 
http://www.springerlink.com/content/t912840551063848/, 
we uses to ( after some imgage processing / frame ) set each frame to a colour. 
The colours made it easier to visually track motion in the wather. 

Used NIH-Image to track position of relevant particles ( size and shape 
criteria ) and saved as cvs-files.
In next step we used a matlab similar program called IGOR to track path of 
particles and plot velocity with arrows.

In case anyone are interested I can send the scripts.

I don't know MatPIV so I cannot comment on this part.

"Toolboxes" are referred to as "packages" in Octave parlance.
Many Octave packages are distributed through the Octave-Forge web-site:

http://octave.sourceforge.net

there is a collection of image processing functions in the "image"  
package:
