franklin

A utility for generating evolutionary art.

What is art?
Something more than sum of its parts.

Description

There are two utilities here: franklin-cli allowing you to generate images through your command line and franklin, a rust library with some out-of-the-box utilities. It also allows you to define your own components to customize generation even more.

The underlying process is my implementation of Evolutionary algorithm. The whole process can be split into three parts:

• mutation - each specimen of the current generation is being randomly mutated.

• scoring - each specimen is being compared with the ideal image (the source) and delta score between those images is calculated.

• crossover - after the scoring the best individual were selected from the generation for breeding. In this step we mix genes of two parents to give birth to new offspring, until new generation with the same size is produced.

Usage

The crate is published on crates.io. You can install it with:

cargo install franklin

cargo is a rust package manager. See here how to set up rust environment.

If you want to start a simulation it's best to check all available options in franklin-cli:

franklin-cli --help

It's also possible to implement your own components, such as mutators, fitness functions or crossover functions. Go to docs, to see more details.

Examples

Here are some examples of images generated with the tool and their CLI arguments.

franklin-cli --image "/temp/Lenna_(test_image).png" -t 7 -m Rectangle -f SquareDistance -c EqualHalfs
    --output-dir "/temp/images" --save-every 100

Source image	Generated image (Generation #3000)

---

franklin-cli --image "/temp/Lenna_(test_image).png" -t 7 -m Triangle -f SquareDistance -c ArithmeticAverage
    --output-dir "/temp/images" --save-every 100

Source image	Generated image (Generation #4000)

---

franklin-cli --image "/temp/Lenna_(test_image).png" -t 7 -m Rectangle -f SquareDistance -c ArithmeticAverage
    --output-dir "/temp/images" --save-every 100

Source image	Generated image (Generation #13000)

franklin-cli --image "/temp/Mona_Lisa_322_480.png" -t 7 -m Rectangle -f SquareDistance -c LeftOrRight
    --output-dir "/temp/images" --save-every 100
