Draw png images onto brain maps. Inspired by a first go at creating "brainilism" images by rendering tiny brains as pixels, now we want to map an entire image onto a single brain. If you really want to see a Christmas spirit network, I think that we found it. Currently supports only square PNG images, and contributions to enhance this appreciated!
See our gallery in NeuroVault
pip install artbrain
This will place an executable, 'artbrain' in your system folder.
usage: artbrain [-h] --input IMAGE [--nopreview] [--output-folder OUTPUT] [--port PORT] draw png images onto brain maps optional arguments: -h, --help show this help message and exit --input IMAGE full path to png image --nopreview don't view output in browser --output-folder OUTPUT output folder for html file --port PORT port for preview, if view is True
Generate an Image
artbrain --input /home/vanessa/Desktop/santa-512.png
It will open in your browser, and you can download the nifti output file using the blue button. You can adjust the colors by clicking on the overlay tables in the top right, or opening the output image in your viewer of choice and changing the color lookup table. To share with your friends, upload the map to NeuroVault or put the entire output folder on a web server.
The "BEST" image types
Photographs don't come out great- best are graphics with a limited set of colors. The color is converted to an integer value and normalized to a Z score, and transparent pixels are substituted with 0s. It has not been tested fully on every possible image type, but generally these kind of images seem to work best.
Don't preview it
By default, preview in the browser is set to True. To disable:
artbrain --input /home/vanessa/Desktop/santa-512.png --nopreview
By default, we rotate three times (3) to produce an upright image. The preview image in the example was not rotated at all. You can specify how many rotations you want:
artbrain --input /home/vanessa/Desktop/santa-512.png --rotate 0
Would be nice to:
- rotate image
- specify orthogonal view
- do more diabolical things!
