python中实现如下任务(a) Load the image 'mandrill.jpg'. (b) Add salt&Pepper noise with different intensities (at least 3 kinds). (Tips: skimage.util.random_noise) (c) Perform smoothing linear filtering to smooth these noised images respectively. (Tips: ImageFilter.BLUR)

and pepper noise to the image. (c) Apply median filter to remove the noise. (d) Display the original image and the filtered image side by side.

以下是实现该任务的 Python 代码：

import cv2

# Load the image
img = cv2.imread('mandrill.jpg')

# Add salt and pepper noise
noise_img = img.copy()
cv2.randu(noise_img, 0, 255)
salt = noise_img > 250
pepper = noise_img < 5
noise_img[salt] = 255
noise_img[pepper] = 0

# Apply median filter
filtered_img = cv2.medianBlur(noise_img, 3)

# Display the images side by side
cv2.imshow('Original Image', img)
cv2.imshow('Filtered Image', filtered_img)
cv2.waitKey(0)
cv2.destroyAllWindows()
