Basic Usage

Concentration

from cymorph.concentration import Concentration
c = Concentration(image, radius1, radius2) 
c.get_concentration()

Asymmetry

from cymorph.asymmetry import Asymmetry
a = Asymmetry(image) 
a.get_pearsonr()
a.get_spearmanr()
a.get_collected_points_plot()

Smoothness

from cymorph.smoothness import Smoothness
s = Smoothness(clean_image, segmented_mask, smoothing_degradation, butterworth_order) 
s.get_pearsonr() 
s.get_spearmanr()
s.get_smoothed_image()
s.get_collected_points_plot()

Entropy

from cymorph.entropy import Entropy
e = Entropy(image, bins) 
e.get_entropy()

G2

from cymorph.g2 import G2
g2 = G2(g2_modular_tolerance, g2_phase_tolerance, g2_position_tolerance) 
g2.get_g2()
g2.get_gradient_plot()
g2.get_asymmetry_gradient_plot()
