8.10.22. nilearn.plotting.plot_img_comparison¶
nilearn.plotting.
plot_img_comparison
(ref_imgs, src_imgs, masker, plot_hist=True, log=True, ref_label='image set 1', src_label='image set 2', output_dir=None, axes=None)¶Creates plots to compare two lists of images and measure correlation.
The first plot displays linear correlation between voxel values. The second plot superimposes histograms to compare values distribution.
Parameters: ref_imgs: nifti_like
Reference images.
src_imgs: nifti_like
Source images.
masker: NiftiMasker object
Mask to be used on data.
plot_hist: Boolean, optional (default True)
If True then histograms of each img in ref_imgs will be plotted along-side the histogram of the corresponding image in src_imgs
log: Boolean, optional (default True)
Passed to plt.hist
ref_label: str
name of reference images
src_label: str
name of source images
output_dir: string, optional (default None)
Directory where plotted figures will be stored.
axes: list of two matplotlib Axes objects, optional (default None)
Can receive a list of the form [ax1, ax2] to render the plots. By default new axes will be created
Returns: corrs: numpy.ndarray
Pearson correlation between the images
