5. Reading notices. ZIP file (982 KB) containing 8 images where a notice (or notices) take up most of each image. Other datasets: ICDAR 2003/2005, ICDAR 2011 Robust Reading Competition.

Mailboxes. A video file (982 KB) which is 63 seconds long (224x380, 1fps) taken of a set of mailboxes where a person is putting in and removing mail.

7. ZIP file (53 MB) containing 2 videos (28s and 27s, 640x360, 25fps) each showing an object being abandoned and later removed. Other datasets: CAVIAR, ViSOR, PETS 2006, PETS 2007.
There are many surveillance datasets provided online. One of the most frequently used datasets in the PETS 2001 dataset..
