Python Matplotlib 并排显示两个图像以比较

import numpy as np import matplotlib.pyplot as plt import cv2 as cv

def show(img): if img.ndim == 2: plt.imshow(img, cmap='gray') else: plt.imshow(cv.cvtColor(img, cv.COLOR_BGR2RGB)) plt.show()

a = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) b = np.array([[9, 8, 7], [6, 5, 4], [3, 2, 1]])

plt.subplot(1, 2, 1) show(a)

plt.subplot(1, 2, 2) show(b)

plt.show()
