Image filters¶

isns.set_image(cmap="inferno") # set default colormap to inferno

User-defined filters or any callable filter function¶
[6]:
from skimage.filters import scharr
ax = isns.filterplot(pol, filt=scharr)
Fast-Fourier Transform¶
[7]:
ax = isns.fftplot(pol)
[8]:
ax = isns.fftplot(pol, window_type="hann")
[9]:
ax = isns.fftplot(pol, shift=False)
