Medical imaging resources were converted to PNG using Python and the nibabel and cv2 dependencies:
image = cv2.resize(nibabel.load().get_fdata()[shape0,shape1,shape2], (dimension0, dimension1))
cv2.imwrite(png_path, image / (image.max() / 255))All PNG files were stripped of any metadata using the optipng command line tool:
optipng -clobber -strip allEach image has its own license, copyright and credits as described in the images.csv table.
