我有以下 MATLAB 代码,并希望在Python中重写它:
mean_ssd = sum(sum((imSrc1 - imSrc2).^2))/numel(imSrc1);
我在 Python 中所做的是以下内容:
width, height = Image.open(open(im1)).size
number_of_pixels = width * height
mean_ssd = sum[math.pow(sum[(imSrc1 - imSrc2)], 2)] / number_of_pixels
但是我在Python中遇到以下错误:
TypeError: unsupported operand type(s) for -: 'instance' and 'instance'
如何在Python中重写MATLAB代码?
感谢。
答案 0 :(得分:0)
试试这个,而不是:
import numpy as np
width, height = np.shape(imSrc1)[1], np.shape(imSrc1)[0]
number_of_pixels = width * height
mean_ssd = ((imSrc1 - imSrc2)**2).sum() / float(number_of_pixels)
