RGB Inputs

[Nicolas]

Hello,

I'm kind of new to using PIVLAB (great tool btw), and I have a very simple question :

How does PIVLAB deal with an RGB input?

I only get a warning saying that 8-bit grayscale would be faster, but does PIVLAB use the colors for the correlations at all, does it convert the image to grayscale, does it use a single channel, none of the above?

Thx for the help

Nevermind,  I found my answer in the soruce code. It simply averages the three channels
