這是一個包含 1、3、6、7、0、4 和 2 類影像的字典。每個鍵中的串列元素表示一個名為 x_data 的陣列中的影像索引，該陣列是一個影像陣列。
我試圖找到同一類中的影像以及其他類中的影像之間的結構相似性。
（（例如將 1 類、索引 52896 影像與 1 類、索引 18945 以及與 3 類、索引 66831 等進行比較））
我想對每張圖片都這樣做
對于結構相似性，我想使用：
from skimage.metrics import structural_similarity as ssim
但是如何為Bold中的陳述句做python雜技。請幫忙。
uj5u.com熱心網友回復：
您必須遍歷每個類，并且在每個類中您必須遍歷每個 id。現在，由于您想將其與其他所有影像進行比較，您將不得不再次重復此操作。
for c1 in img_classes:
for i1 in img_classes[c1]:
for c2 in img_classes:
for i2 in img_classes[c2]:
# Compare image i1 of class c1 with image i2 of class c2
val = ssim(images[i1], images[i2], multichannel=True)
print(f"Comparing image {i1:5d} of class {c1} with image {i2:5d} of class {c2} || SSIM :{val:.4f}")
