what do you mean by "change"?<br>
<br>
<br>
the 2nd-last outlet of [pix_info] should give you the information<br>
whether a "newly acquired" image is sent down the pipe.<br>
this newly acquired image might be identical (pixelwise) to the last one.<br>
<br>
if you want a pixel-wise comparision, try [pix_movement]/[pix_mean_color].<br>
