```python
|

|

for f in files:
|
|
30
|
+
img = cv2.imread(f)
|
|
31

color = ('b','g','r')

hists = []
|

fig = plt.figure()

for i, col in enumerate(color):
|
|
35
|

hist = cv2.calcHist([img], [i], None, [256], [0, 256])
|
|
36
|

hists.append(hist.squeeze(axis=-1))
|

plt.plot(hist, color=col)

np.savetxt(f"output/{fnm}.csv",hists,delimiter=",")
|

```
|
|

|

これでどうでしょうか。
