Sources of Images

There are a lot of images hanging around the department in various formats. One source of iff images is my directory /u/nelson/pics, which has a number of (mostly) grayscale images of different sorts. You are welcome to browse.
The directories under /p/imagedb (s4, s11, s16, s30) contain a very large collection of images, consisting of views taken about every 20 degrees over a sphere or hemisphere for a number of different objects. There are training image sets of 50 - 100 images each for about 100 different objects, plus additional test images. All the training images and most of the test sets are on black velvet. They were acquired for testing object recognition systems, but there may be other uses. There are various other collections also in this directory.
Another source of images is the web. You can find a lot of pictures out there, typically as gifs, but sometimes in other formats. XV is useful for converting these into your preferred format.
Finally, you can take your own pictures; in fact, you will be required to take some during the course. This means learning to make use of the cameras and digitizers in the department.
