Of course. The figure 7 is the polar map comparison of images before and after alignment.

for i in range(length):

r, theta = cmath.polar(cor)
r_polar.append(r)
theta_polar.append(theta)
ax = fig.add_subplot(111, projection='polar')
ax.set_ylim(0, 20)
ax.set_yticks(np.arange(0, 20, 1.0))
c = ax.scatter(theta_polar, r_polar, c=colormap[number-1], s=1, cmap='hsv', alpha=0.75)
save_name = '{}_polar_map.png'.format(LR_list)
plt.savefig(os.path.join(save_path,save_name))
plt.close('all')
Could you please provide the code for reproducing Fig. 7 in the paper? Thanks for your help!
