Fractal-Mosaics
|
||
===============
|
||
|
||
Fractal Mosaics is a rotation, scale, and translation invariant photomosaic algorithm (i.e., the images can be placed at arbitrary locations, can be scaled to any size, and can be rotated by any angle).
|
||
|
||
The figure below shows a Fractal Mosaic and traditional photomosaic made using the same target image and image set.
|
||
|
||
|
||
|
||
For a detailed description of the algorithm, see my "[paper](http://s-ben.github.io/Fractal-Mosaics/)" on it and documentation links below.
|
||
|
||
# Prerequisites
|
||
|
||
Fractal Mosaics is implemented in Matlab. You’ll need a copy of Matlab with the Signal Processing toolbox installed (any version should work, most should come with the Signal Processing toolbox).
|
||
|
||
|
||
# Getting Started
|
||
|
||
1. Download the demo example. This has all the code you need. Simply modify the example to create your own mosaics.
|
||
2. Download the example image set (706 MB database of images of San Francisco).
|
||
3. Unpack zip file with images into the /library_images folder in the demo example.
|
||
4. Navigate to the /m-files directory
|
||
5. Run ‘fractal_mosaic.m’
|
||
|
||
Your mosaic is now rendering.
|
||
|
||
WARNING: it takes a long time to render a mosaic (~6 to 8 hrs on my macbook pro). If you want to optimize it, please do ;)
|
||
|
||
The demo example creates a black and white mosaic. This is because color takes ~3X as long. To create a color mosaic, download the color image set, and set Fractal Mosaics to color mode (see the Variables page for info on this).
