Where can I obtain test stereo images?

Some test images are available at:

    http://sluggish.homelinux.net/datasets/libviso_test_images1.tar.gz

or alternatively you can download the libviso source code from:

    http://www.rainsoft.de/software/libviso.html

and convert the jpeg files into png format with:

    mogrify -format png *.jpg
