je suis nouveau dans la programmation python et je suis sur le point de réaliser un scanner 3d linaire et j'ai eu des problème lors de la compilation du code
"import numpy as np
import scipy
import scipy.ndimage as ndimage
import scipy.ndimage.filters as filters
import matplotlib.pyplot as plt
import cv2
fname = '/home/mehdi/Bureau/mehdi.jpg'
neighborhood_size = 5
threshold = 1500
scale1 = 0.1292
scale2 = 0.03175
data = cv2.imread('fname',0)
data_max = filters.maximum_filter(data, neighborhood_size)
maxima = (data == data_max)
data_min = filters.minimum_filter(data, neighborhood_size)
diff = ((data_max - data_min) > threshold)
maxima[diff == 0] = 0
labeled, num_objects = ndimage.label(maxima)
slices = ndimage.find_objects(labeled)
for dy,dx in slices:
x_center = (dx.start + dx.stop - 1)/2
y_center = (dy.start + dy.stop - 1)/2
if x_center > 500 and x_center < 621:
xx1.append((x_center*scale1)+(fileloop*scale2))
yy1.append(y_center*scale1)
zz1.append((621-x_center)*1.0*scale1)"
et voici le message d'erreur
" diff = ((data_max + data_min) > threshold)
TypeError: unsupported operand type(s) for -: 'NoneType' and 'NoneType'"

Salut
