To Dave Robinson, and others.

I have some further question for the scholar :)

The result was actually not as I hoped it would be. The 
values for the mean background and the std.deviation is 
decimal numbers. The values of each frame I load and 
eventually convert to binary is all integer numbers. Should 
these be converted to decimals also? Should maybe each 
frame processed be normalized as well?

What I get know is no motion at all, it does not registar 
any movement. This maybe because the because the I have 
decimals one place and integers another place, or that they 
are not converted into the same datarange. So, that the 
comparison of the values in a fram against the standard 
deviation reveals too low values all over the image, which 
indicates no movement.

I might be missing one step in my code here. If you want, I 
can upload my m-files to a server, if you want to take a 
look at the overall process.

Thanks, Helmer.
