Mutate

mutate is a command line tool for generating many new versions of images by applying and compositing random image operations. This can be useful when generating large amounts neural networking training data, which is exactly why the tool was created.

Example output images

Example usage

Create 10 new version of lena.jpg, will create lena-1.jpg, lena-2.jpg, ..., lena-n.jpg.

$ mutate -n 10 lena.jpg

Create 1 new version of lena.jpg, applying 50 random operations before saving:

$ mutate -n 1 -p 50 lena.jpg

Create 10,000 new versions of lena.jpg, slightly lowered chaos level and 15 operations per image, save the results in the directory /srv/storage0:

$ mutate -n 10000 -p 15 -c 0.15 lena.jpg -o /srv/storage0

The montage in this README was generated with:

$ mutate -n 42 -c 0.15 lena.jpg -o out/
$ montage out/*.jpg example.jpg # imagemagick tool

Building and dependencies

mutate depends on ImageMagick/MagickWand.

Debian users:

$ sudo apt-get install libmagickwand-dev

Building and running:

$ make
$ ./mutate -n 1 -p 10 lena.jpg

Mutate
mutate is a command line tool for generating many new versions of images by applying and compositing random image operations. This can be useful when generating large amounts neural networking training data, which is exactly why the tool was created.
Example output images
Example usage
Create 10 new version of lena.jpg, will create lena-1.jpg, lena-2.jpg, ..., lena-n.jpg.
$ mutate -n 10 lena.jpg

Create 1 new version of lena.jpg, applying 50 random operations before saving:
$ mutate -n 1 -p 50 lena.jpg

Create 10,000 new versions of lena.jpg, slightly lowered chaos level and 15 operations per image, save the results in the directory /srv/storage0:
$ mutate -n 10000 -p 15 -c 0.15 lena.jpg -o /srv/storage0

The montage in this README was generated with:
$ mutate -n 42 -c 0.15 lena.jpg -o out/
$ montage out/*.jpg example.jpg # imagemagick tool

Building and dependencies
mutate depends on ImageMagick/MagickWand.
Debian users:
$ sudo apt-get install libmagickwand-dev

Building and running:
$ make
$ ./mutate -n 1 -p 10 lena.jpg
