Question

我想使用ssim比较2张图片中的相似度。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 )

Traceback（最近一次调用最后一次）：文件“”，第1行，in 文件 “/var/www/wt/local/lib/python2.7/site-packages/skimage/measure/_structural_similarity.py” 第58行，结构相似性 XW = view_as_windows（X，（win_size，win_size））文件“/var/www/wt/local/lib/python2.7/site-packages/skimage/util/shape.py”，第221行，在view_as_windows中引发ValueError（“window_shape与arr_in.shape不兼容”）ValueError：window_shape与 arr_in.shape

即使我将同一个文件同时输入ssim(img1,img1)

，我也会收到同样的错误

您需要确保您的图片大小相同，以便与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)

ssim image比较错误''window_shape与arr_in.shape不兼容“
