Anyone know the right word to describe an image which is constructed from many copies of a smaller image in a haphazard or random manner?

If the smaller image copies were butted up to each other without gaps or overlap we would have a tesselation, but in my case overlap and gaps are allowed - see attached images. The "not quite tesselated" images are seamless and I want the right word to describe them.

"Collage" is another word that springs to mind - but that involves copies of different images put into a single image.

Any suggestions?

edit - removed

thought you were making an actual image rather than a random texture.

GG - i dont think there's any type of category beside 'seamless pattern' those images would fall under. there's no geometry to them, that i can see, nor pattern inside them; they are simply seamless patterns.

check this google image search for seamless pattern.

if there is a specific category, those images may lead you to it. (i went through the first 20 pages of thumbnails and didn't see one that used a single image, scattered chaotically except for the edges, like yours).

edit: k. i went through 42 'safe search' pages (that's all that came up without 'repeating'). same result

Yes, that was another word that occurred to me - but it tends to convey the idea of several different images used in an irregular tesselation , rather than a single image replicated randomly with overlapping.

Quote: "seamless pattern"


That seems close - but still a bit of a mouthful to have to say "a small image replicated in an irregular seamless pattern". It would be nice to just say "a small image arranged as a ???".

Thanks for the suggestions. Perhaps we should coin our own word specifically for the purpose? For example,

decalation
collaic
tosaic
mosselation

?

Edit "Applique" and "decal" are two relevant words - and effectively describe the process by which the images are constructed - but what's the right word for the final image?

heh. well i was thinking "handmade pattern".

i've probably spent another hour now searching for the answer to this (assuming there is an answer). dunno why. it's got a hold of me!

i would have to categorically rule out any of the terms mentioned thus far... including 'pattern' (because of what it implies). mainly because there doesn't seem to be any math behind this and/or there is only a single image involved.

so, how were the images constructed?

if the single images were simply run through photoshop pattern maker (or the like) with off-set and wrap-around added, there should be a definition since it uses some math and parameters. i supposed you could look into the nuts and bolts of the procedures used by adobe.

alternatively, i wrote a small application some time ago (in dbpro) that was a simple pattern-maker. it pasted whatever image i used as a 'brush' and whenever i got close to the edge(s), it automatically pasted the images at the opposite edge(s), too (with appropriate offset), effecting a wrap-around, and a seamless pattern. (actually, i used sprites so i could have an endless 'undo' feature). i never bothered to add math functions, etc, because what i was doing at the time didn't warrant it.

anyway. point is, if you used some 'method', then that's probably where to start defining this. otherwise, maybe 'handmade pattern' is the way to go...

oh, how about "SIMNN" ? "Single Image Mostly-random Non-Dot Non-Stereogram" (yeah, this has fried my brain... heh)

Hand- and computer-made in fact.

Quote: "alternatively, i wrote a small application some time ago (in dbpro) that was a simple pattern-maker. it pasted whatever image i used as a 'brush' and whenever i got close to the edge(s), it automatically pasted the images at the opposite edge(s), too (with appropriate offset), effecting a wrap-around, and a seamless pattern."


Pretty much what I did - except I used a masking procedure so that overlapping only happens as you go down the image.

Quote: "yeah, this has fried my brain..."


Looks like it - but I know the feeling, I can't believe there isn't a word for it. I don't care if it's French, Spanish, Latin, Egyptian, etc, as long as it's not a twenty word description.

And life used to be so easy ...

The effect reminds me of roof tiles, except for the unevenness.

Uneven tiling? Random tiling?

Good point - but I'd prefer a different word. "Tiling" is too commonly used to describe non-overlapping of textures as in Advanced Terrain. Perhaps there's a specific word to describe "roof tiling"? If not in English, another language perhaps?

Following IanM's line of thought, I'm very tempted to call it a thatched image to get away from the usual interpretation of "tile" in computer graphics.

Or, referring to one of my examples, a feathered image, perhaps?

I started down this route because I wanted to create an image resembling scaled reptilian skin - and rejected scaled image for the obvious reason.

We seem to have a number of promising candidates now. Soon be time for a vote.

No, that is associated with an image that "feathers" away to transparency at the edges.

I like Mosselation, as you suggested earlier

Agreed. [I'm surprised you've let me get away with the spelling mistake. ]

Reptile scales are (usually) arranged in regular patterns though, so why not use 'pattern'? Your image isn't generated as a pattern, but if reptile scales are what you are after, it should be, no?

No - the scales are very rarely arranged in a perfect pattern. The positions, shape/size and colouring of the scales almost always vary somewhat. My application allows you to decide how much departure from perfect regularity to use. And scales do overlap of course.

Anyway, it's the word I'm really want at the moment.

Dang! I've seen it long ago but I can't for the life of me recall what we called it. I'm fairly sure it wasn't a single word, but rather a two or three word phrase. If it serves as any lead: I had a hippy friend in the 60's who would invite us over when her parents were out, and we'd repetitively stamp patterns like that on the walls using some half-potatoes we had carved into some base images like flower petals or peace signs or whatever. Naturally the spacings were uneven and the overlap margin variable. We called it something, but I can't remember what.

What did her parents call it?

Vandalism? Graffiti?

Sorry, only joking.

Food for thought though. Perhaps I should ask one of my artistic friends - who probably also remembers decorating with potatoes?

At the moment, variations of Virtual Nomad's suggestions seem to fit the bill, e.g.

handmade pattern
seamless pattern
irregular seamless pattern

but somehow don't quite grab the imagination. A single word like mosaic, collage, tessellation (spelling corrected this time ) etc, would be better.

Interesting suggestion.

Here's a relevant link - I particularly liked the Fraser Spiral.

mandalas and things

Not what I want though.
