pycollage 0.0.0

Recreate an image with many others

Create collages of images.

Installation

Install the package via either of these options:

1. $ git clone https://github.com/kklein/pycollage.git
   $ conda env create -f environment.yml
   $ conda activate pycollage
   $ pip install --no-build-isolation -e .
   

2. $ pip install pycollage
3. $ conda install pycollage -c conda-forge

Usage

In order to use pycollage, you should have a collection of images which makes up for the individual components of the collage as well as a target image which the collage seeks to imitate.

In the following we will assume that you saved the image collection under /users/Anne/image_collection and the target image under /users/Anne/target_image.png. Best use absolute paths.

Processing the collection

The first step consists of processing the image collection. In order to do so, run

$ pycollage process-collection /users/Anne/image_collection

By default, this will resize the images to each be 20x20 pixels. If you'd like a different component size, e.g. 30x30 pixels, run

$ pycollage process-collection /users/Anne/image_collection --component_size 30

instead.

You will notice that executing this will tell you where an index directory has been created. Given the paths from above, this should be /uers/Anne/index. Moreover another new directory has been created: /users/Anne/image_collection_resized.

Building a collage

Now that the collection has been duely processed, we can embark onto actually building a collage.

For that purpose, simply run

$ pycollage build /users/Anne/index /users/Anne/target_image

where the first path corresponds to the path that was mentioned to you when executing process_collection.

At the end of the process both the original target image as well as the collage imitating the target image will be opened. You can then save the collage to wherever you like.

Runtime

Note that this process will take longer

• the larger the component_size you provide
• the larger your collection of images
• the larger the resolution of the target image

Since the collage will scale up the original target image by component_size per dimensions - i.e., 20 by default - you might want to scale down your original target image to below 1000x1000 pixels.
