Mosaic Maker
============

[](#mosaic-maker)

A set of PHP classes for assembling a mosaic, designed to look like a given guide image, using a set of source images.

Usage
-----

[](#usage)

Pick a directory where the temp folder (used for caching source image data) can be kept. Open a command prompt in that folder, and run the following:

```
php

```

Replace the values in angle brackets with actual paths. For example, replace `` with something like `"C:\code\mosaic\cli.php"`(depending on where you cloned this repo to on your computer). Note that any additional command-line parameters are treated as additional folders containing source images to be used for generating the mosaic.

**The first time you run this**, it will probably take quite some time since it has not yet cached downsized copies of your source images (and therefor it has to do a lot of image resizing). The next (and subsequent) times should be much faster.

Basic Approach
--------------

[](#basic-approach)

A. Get guide image. B. Get source images. C. Slice up guide image. D. Match up each slice of the guide image with a different source image. E. Assemble and save mosaic.

---

C.1. Count source images. 2. Slice guide image into no more than that many slices.

---

D.1. Downsize the slice to 3 pixels by 3 pixels. Record the RGB values of the pixels. 2. Compare that with each of the source images. 3. Make a note of which unused source image matches this slice best.

---

D.2.a. Downsize the source image to 3 pixels by 3 pixels. Record the RGB values of the pixels. b. Calculate the absolute difference of slice's pixels' colors with this source image's pixels' colors.

---

E.1. Create a new empty image. 2. Insert each of the source images according to the matches found.

---

Match accuracy (at a given resolution) = D\[1\] + D\[2\] + ... + D\[number of pixels\]

D = abs(R\[a\] - R\[b\]) + abs(G\[a\] - G\[b\]) + abs(B\[a\] - B\[b\])

Only accuracy calculations at matching resolutions give a meaningful comparison.

Glossary
--------

[](#glossary)

- *guide image*: The image that the mosaic is trying to mimic.
- *slice* (aka. guide image slice): A portion of the original guide image.
- *source images*: The images being used to recreate the guide image as a mosaic.
