Hi,

I wrote a little test script using Liu's optical flow (using conjugate gradient), and I ran into a strange behaviour:

• when I load two color images of size 72*72 pixels, everything is fine :)
• when I load the same color images, downscaled to 36*36 pixels (downscaling done by bob), I get a segmentation fault.

Note that the two sets of two images have been processed the exact same way after having been loaded and before the call to bob.ip.optflow.liu.cg.flow: casted to float and divided by 255, and then converted to grayscale ...

Thanks, Guillaume
