## Creating Mosaic Art using AI

This repository includes the code (and other files) for creating [mosaic art](https://en.wikipedia.org/wiki/Mosaic)
versions of a given image. Given an image
(referred to as the original image), the main idea is to replace (square-shaped) patches of the original image with the
most similar image from a given set of images (referred to as the tile images or simply tiles).

The implementation uses the [Stable Diffusion](https://en.wikipedia.org/wiki/Stable_Diffusion) model available from
[keras-cv](https://github.com/keras-team/keras-cv) submodule of [Keras](https://keras.io/) to create the tiles.
It allows limitless creativity by creating mosaic art of the same image using different tiles created by changing
the model's parameters and using different text prompts.

In the examples below, each row shows an (original) image and two mosaic art images created from it.
The left-most image is the original image, and the middle image is the mosaic art created using 2,500 tiles, and the
right-most image is the mosaic art created using 90,000 tiles.

### Getting started

#### Project Structure

The main files and folders included in this repository are:

1. [images/canvases](images/canvases): This folder includes the images. Place your image files in this folder
   to create mosaic art versions of them. Please note that the images must have the same dimensions (width and
   height).
2. [images/tiles](images/tiles): This folder includes the tile images. There are already some tile images in this
   folder. You can use an instance of MosiacArtMaker to create your own custom set of tile images and put them in
   the `images/tiles` folder.
3. [images/output](images/outputs): The mosaic art images are saved in this folder.
4. [notebooks/make_mosaic_art.ipynb](notebooks/make_mosaic_art.ipynb): This notebook includes the code for creating
   mosaic
   art versions of the images in the `images/canvases` folder and also the code for creating the
   tile images.

#### Setting Up Python Environment

```shell
# Clone the repository
git clone https://github.com/habedi/mosaic-art-maker

# Change the working directory
cd mosaic-art-maker

# Create a Poetry environment and install the dependencies (need Poetry installed)
poetry install --no-root
```

#### Running the Code

Open [Making Mosaic Art using KerasCV+StableDiffusion](notebooks/make_mosaic_art.ipynb) notebook to see the code.

Furthermore, you can modify the variables and parameters in the main function (shown below) to create your own mosaic
art versions of the given images. You can place your images in the `images/canvases` folder if you want to
create mosaic art versions of them.

```python
def main(remake_tiles: bool) -> None:
    """Main function to pack everything together and run it"""

# Extension to use for saving and loading the tile images
    tile_file_extension = "jpeg"

# (Re)-make the tile images if the user wants to do so
    if remake_tiles:

# Create a MosaicMaker object to make the tile images
        image_maker = MosaicMaker(img_width=400, img_height=400, jit_compile=False, seed=33)

# The text prompts to be used to make the tile images
        prompt_seq = (("A laughing woman", ("realistic", "white background")),
                      ("A sad girl", ("realistic", "white background")),
                      ("An old man", ("realistic", "white background")),
                      ("Face of a sad man", ("realistic", "white background")),
                      ("Drawing of rings of Saturn", ("abstract", "white background")),
                      ("A watercolor painting of a puppy", ("detailed",)),
                      ("Drawing of a red rose", ("elegant", "detailed", "white background")),
                      ("View of a green forest with mountains in the background", ("elegant", "lush", "nature")),
                      ("A painting of four oranges in a bowl", ("elegant", "detailed", "white background")),
                      ("A ninja shuriken", ("realistic", "metal", "white background")),)

# Make the tile images and save them
        for index, prompt_data in enumerate(prompt_seq):
            image_seq = image_maker.make_images(prompt_data[0], prompt_data[1], num_images=40)
            image_maker.save_images(img_seq=image_seq, path='images/tiles', prefix=f'p{index}',
                                    extension=tile_file_extension)

# Use the images in the images/canvases and images/tiles directories to make mosaic arts
    for canvas_image_path in pathlib.Path("images/canvases").glob("*.png"):
        # Create a MosaicArtMaker object with about sqrt_num_tiles*sqrt_num_tiles tiles!
        art_maker = MosaicArtMaker(original_image_path=canvas_image_path, sqrt_num_tiles=300,
                                   tile_file_extension=tile_file_extension)

# Make the mosaic art and save it in the images/outputs directory
        output_image = art_maker.make_mosaic_art(k=40)
        print(f"Created a mosaic art version of '{art_maker.original_image_path}' using "
              f"{art_maker.sqrt_num_tiles * art_maker.sqrt_num_tiles} smaller images created by a Stable Diffusion model")
        art_maker.save_images((output_image,), path='images/outputs',
                              prefix=f'{art_maker.original_image_name}_mosaic_art')

# Display each original image and its mosaic art version
        art_maker.display_images((art_maker.original_image, output_image),
                                 (art_maker.original_image_name, art_maker.original_image_name + "_mosaic_art"))
```

Run the main function to execute the code. If you want to remake the tile images, set the `remake_tiles` parameter
to `True`. Note that creating a new set of tile images might take a while, so it is recommended to use the current tile
images in the beginning by setting `remake_tiles` to `False`.

```python
main(remake_tiles=False)
```

#### Kaggle notebook

The notebook is available on Kaggle now. You can open it
using [this link](https://www.kaggle.com/code/habedi/creating-mosaic-art-using-kerascv-stablediffusion).

### Ideas for improvement

- [x] Adding a link to a Kaggle or Colab version of the notebook.

<del>- [ ] Using different shapes instead of squares (of the same size) for the tiles. For example, trapezoids or
triangles. </del>

<del>- [ ] Using different tile images for different parts of the original image. For example, using a set of images
containing faces for the faces in the original image, and using a set of images containing landscapes for the
background in the original image. </del>

<del>- [ ] Using better similarity metrics for comparing the tiles with a patch from the original image. For example,
using the [SSIM](https://en.wikipedia.org/wiki/Structural_similarity) metric instead of the Euclidean distance. </del>

### Credits

- [KerasCV](https://keras.io/keras_cv): The code for creating the tile images uses
  the StableDiffusion model available from KerasCV.
- The idea for creating mosaic art versions of images using a collection of tile images is inspired
  by [this post](https://medium.com/@aarongrove/creating-image-mosaics-with-python-8e4c25dd9bf9).
