使用python编写高斯滤波、中值滤波、均值滤波算法

以下是使用Python编写高斯滤波、中值滤波和均值滤波算法的示例代码：

1. 高斯滤波：

import cv2

def gaussian_blur(image, kernel_size, sigma):
    blurred_image = cv2.GaussianBlur(image, (kernel_size, kernel_size), sigma)
    return blurred_image

# 示例用法
image = cv2.imread('image.jpg')
blurred_image = gaussian_blur(image, 5, 0)
cv2.imshow('Blurred Image', blurred_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

2. 中值滤波：

import cv2

def median_blur(image, kernel_size):
    blurred_image = cv2.medianBlur(image, kernel_size)
    return blurred_image

# 示例用法
image = cv2.imread('image.jpg')
blurred_image = median_blur(image, 5)
cv2.imshow('Blurred Image', blurred_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

3. 均值滤波：

import cv2

def mean_blur(image, kernel_size):
    blurred_image = cv2.blur(image, (kernel_size, kernel_size))
    return blurred_image

# 示例用法
image = cv2.imread('image.jpg')
blurred_image = mean_blur(image, 5)
cv2.imshow('Blurred Image', blurred_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
