Artificial

The Artificial Image Catalogue contains a collection of computer generated binary images. Most images contain a single (of very few) instance(s) of a geometric shape (constructed using, e.g. a paint program), however, there are some more sophisticated computer graphics (e.g. generated by modeling software).

(art1): 222×217 binary of circles and lines.
(art2): 205×245 binary of criss-cross lines.
(art3): 222×217 binary inversion of art1.
(art4): 300×300 binary of circle filled with holes.
(art5): 256×256 binary of rectangle.
(art6): 256×256 binary of rounded, elongated object.
(art7): 256×256 binary of skewed doughnut shaped object.
(art8): 256×256 binary of multiple crosses.
(art9): 323×300 binary of propeller shaped object.
(che1): 256×256 grayscale of chess board.
(cir1): 171×150 binary of doughnut shaped object.
(cir2): 512×512 binary circle centered in the right of the image.
(cir3): 512×512 binary circle centered in the left of the image.

(i.e. the pixel addition of stp1 and stp2).
