Python package and CLI utility to create photo mosaics.
phomo
lets you create photographic mosaics. It arranges the tile images to best recreate a master image. To achieve this, phomo
computes a distance matrix between all the tiles and the master image regions, looking not just at the average colour but the norm of the colour distributions differences. Once this distance matrix is computed, each tile is assigned to the region of the master with the smallest distance between the colour distributions.
Installation
Requires python 3
In a terminal:
$ pip install phomo
As always, it is usually a good idea to use a virtual environment.
If you're just interested in command line usage, consider using pipx.
Usage
Python package
See the examples
folder for usage as a python package.
CLI
Once it is installed, you can use the phomo
command.
It would go something like:
$ phomo master.png tile_directory -S 20 20 -o mosaic.png
If in doubt see the help:
usage: phomo [-h] [-o OUTPUT] [-c MASTER_CROP_RATIO] [-s MASTER_SIZE [MASTER_SIZE ...]]
[-C TILE_CROP_RATIO] [-S TILE_SIZE [TILE_SIZE ...]] [-n N_APPEARANCES] [-v] [-b] [-g]
[-d SUBDIVISIONS [SUBDIVISIONS ...]]
master tile_dir
positional arguments:
master Master image path.
tile_dir Directory containing the tile images.
optional arguments:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
Mosiac output path.
-c MASTER_CROP_RATIO, --master-crop-ratio MASTER_CROP_RATIO
Crop the master image to width/height ratio.
-s MASTER_SIZE [MASTER_SIZE ...], --master-size MASTER_SIZE [MASTER_SIZE ...]
Resize master image to width, height.
-C TILE_CROP_RATIO, --tile-crop-ratio TILE_CROP_RATIO
Crop the tile images to width/height ratio.
-S TILE_SIZE [TILE_SIZE ...], --tile-size TILE_SIZE [TILE_SIZE ...]
Resize tile images to width, height.
-n N_APPEARANCES, --n-appearances N_APPEARANCES
The number of times a tile can appear in the mosaic.
-v, --verbose Verbosity.
-b, --black_and_white
Black and white.
-g, --show-grid Show the tile grid, don't build the mosiac.
-d SUBDIVISIONS [SUBDIVISIONS ...], --subdivisions SUBDIVISIONS [SUBDIVISIONS ...]
Grid subdivision thresholds.
Note
The grid subdivision feature was inspired by photomosaic.

- look into non greedy tile assignments
- look into parallelizing/multithreading
- palette matching
