The software behind the magic of a Doubletake mosaic has been in development for over twelve years and its sophistication and capablilities extend far beyond any commercial software.

So why does this matter?

When creating a mosaic image from a collection of drawings or photographs, there are trillions of possible ways that the image can be put together. But there's only one right way! And if you don't happen to get it right the image will look splotchy and pixelated.

Just because a tile happens to fit into a particular area of the mosaic doesn't mean that it should be placed there. Perhaps another picture (that fits almost as well) could go there, and the other used to fill a different position.

So Doubletake's software uses a unique approach. It doesn't try and find the best possible placement for each individual tile. Using a process called artificial evolution, the software takes three random guesses at the best combination. The guess that looks the best (based on a proprietary scoring system) spawns three more guesses each slightly different from its parent. This organic process is repeated until no further improvment is possible.

The resulting mosaic is smooth, organic, and with graduated tonal ranges.

But the real work comes in the analysis and adjustment of the main image prior to building the mosaic. This is the true art of mosaic making, and it takes years of experience to understand how the main image will integrate with the component tiles. It is how Doubletake was able to create the high resolution mosaics for Disneyland's 50th Anniversary, and enables it to make minimilist mosaics.

Doubletake's software is capable of rendering full motion mosaics, invisible mosaics, impressionist mosaics. The mosaic software is also capable of tracking the locations of each small picture, making its unique sport posters possible.
