python - ssim图片比较错误 '' window_shape与arr_in.shape不兼容”

我想使用ssim在2个图像中比较相似性。
我收到此错误window_shape is incompatible with arr_in.shape。
为什么？ (这是什么意思？)

from skimage.measure import structural_similarity as ssim
from skimage import io

img1 = io.imread('http://pasteio.com/m85cc2eed18c661bf8a0ea7e43779e742')
img2 = io.imread('http://pasteio.com/m1d45b9c70afdb576f1e3b33d342bf7d0')

ssim( img1, img2 )

即使两次向同一文件输入相同的文件，我也会收到相同的错误ssim(img1,img1)

最佳答案

您需要确保图像大小相同，才能将其与scikit的ssim进行比较:

from skimage.measure import compare_ssim
from skimage.transform import resize
from scipy.ndimage import imread
import numpy as np

# resized image sizes
height = 2**10
width = 2**10

a = imread('a.jpg', flatten=True).astype(np.uint8)
b = imread('b.jpg', flatten=True).astype(np.uint8)
a = resize(a, (height, width))
b = resize(b, (height, width))

sim, diff = compare_ssim(a, b, full=True)
