Cannot visualize the Segmentation

[Bananaboy99]

Hey,
I am getting just a black image if I am trying to visualize the predicted image.

imgs = sitk.GetArrayFromImage(sitk.ReadImage(tests[10]))
plist = []

create patches from an entire slice

for img in imgs[:-1]:
if np.max(img) != 0:
img /= np.max(img)
p = extract_patches_2d(img, (33,33))
plist.append(p)
patches = np.array(zip(np.array(plist[0]), np.array(plist[1]), np.array(plist[2]), np.array(plist[3])))

predict classes of each pixel based on model

full_pred = model.predict_classes(patches)
fp1 = full_pred.reshape(208,208

full_pred = model.predict_classes(imgs)
imgs = sitk.GetArrayFromImage(sitk.ReadImage(tests[10]))

plt.figure(figsize=(10,10))
plt.subplot(121)
plt.imshow(imgs[70])
plt.subplot(122)
plt.imshow(fp1)
plt.show()

I am trying to create an image with the Segmentation like in the description. But with the code it does not work. Can somebody help me out
