[SIP-devel] test sip-0.2-bin release + imvariance function

[DRUEL J. <joc...@li...>]

Hi Riccardo,
I tested sip-0.2-bin for scilab-2.6 on my linux box this morning.
Great job: no problem with it: a simple exec('loader.sce') and it works !

It seems difficult to have a more easy to install toolbox for scilab.

Just because I'm curious, I tried this binary for scilab-2.6 on the 2.7 
version of scilab.
The few functions I tested work allright. 
Why 2 binary versions (but maybe I should continue testing ?) for linux ?

Linux version: debian-woody (kernel 2.4)


Still working on my problem of phase unwrapping, I wrote a imvariance 
function.

I saw a "variance" function in the statistic toolbox. But it did not answer 
my needs. Maybe I did not search enough to make it work the way I wanted. It 
was easier for me to write a new function "imvariance" which does what I want 
it to do:
 it calculate the sum of absolute value of the differences between a central 
pixel and its 8 neighbours.

I think the code is easy to understand. I avoided "for" loops to have speed.

Best regards
Jocelyn
