These are typical test images. You should be able to find your own comparable images.
racepoint.img cols = 1024 (width) rows = 820 (height) colors = 1 This is the beach on Cape Cod. The sharp detail is useful for testing edge-based algorithms. |
|
david.img rows = 780 (height) colors = 3 The statue by Michaelangelo. Note the relatively few number of distinct colors in this image. |
|
fire.img cols = 513 (width) rows = 372 (height) colors = 1 This image uses the full range of gray levels and has fine detail. |
|
friends.img cols = 640 (width) rows = 480 (height) colors = 3 This image has an unsually high level of contrast. |
|
rover.img cols = 288 (width) rows = 279 (height) colors = 1 This is the NASA rover Sojourner on the surface of Mars. Note that the original of this image has already been histogram equalized. |
|
io.img cols = 493 (width) rows = 493 (height) colors = 1 This is an image of Io, a moon of Saturn. Although the full range of gray levels has been used, they are not uniformly distributed. |
logo.img cols = 500 (width) rows = 313 (height) colors = 1 This image is useful for testing algorithms based on derivatives. All gray scale changes are gradual except for the edge of the "sphere". |
|
telescope.img cols = 600 (width) rows = 400 (height) colors = 1 This image contains high- and low-contrast edges in all direction. It is worth looking at the histogram of this image before using it. |
|
king.img cols = 400 (width) rows = 340 (height) colors = 1 This image contains large areas of smooth gray levels |
|
galaxy.img cols = 743 (width) rows = 586 (height) colors = 1 This image contains many small star images - only one or two pixels. |
cols = 189 (width) rows = 247 (height) colors = 3 or 1 This image is useful for testing image restoration algorithms. |
