Image Repository

The image repository is divided into three sets:

  1. Greyscale Set 1: 12 small greyscale images
  2. Greyscale Set 2: 12 medium greyscale images
  3. Color Set: 8 large full color images

Most of our images are may be downloaded in gif, pmg, raw, tga, and tif format, here. You can also download individual images (in tif format) by clicking on the thumbnails below.

Greyscale Set 1

There are twelve images in GreySet1. Some are photographic pictures, others are synthetic; one is a montage of four smaller pieces. This mix helps to evaluate the performance of an image processing algorithm on various kinds of graphical material (e.g. landscapes, portraits, text, computer graphics, etc.). All images are 256x256x8.

Greyscale Set 2

There are twelve images in GreySet2. Most are photographic pictures and many are 'classics' of the image processing literature. For some reason, the classics tend to be 512x512 pixels in size. To make this set more challenging, some images with unusual dimensions are included.
