ball3
Description
The ``BALL'' sequence (BALL1 through BALL7) depicts a
single centered tennis ball, resting on a lightly textured planar
ground. There are a few dark dots on the ground. A toy railroad track
runs across the foreground. The image pairs differ in contrast, with
successive pairs being increasingly dimmer. The result of this
reduction is that the last few pairs are barely viewable. This
reduction in contrast decreases the image's signal to noise, so
provides a test of a system's noise sensitivity.
Principal Scene Features - Accurate recovery of the ball's boundary is
a challenge. The railroad track is highly ambiguous, with its
repeated pattern of basically identical vertical bars.

Currently, only .png format is supported. In the future, you will be able to download images in other formats as well.Pressing the "Download" button will send a .tar file to your machine. The .tar file is not compressed because the images already are. You will need tar to decompress the archive. Any additional information (such as ground truth) will be included in the archive.
Note - the resulting file will be called 'maketar.pl'. Just rename it when you download it and extract it.
Finally, it can take a bit of time to tar up everything for download. Don't quit because it doesn't immediately return.
This .tar file will be 212 K large.
