如何消除模糊边缘上的光晕？

import cv2

# 读取图像
image = cv2.imread('path_to_image.jpg')

# 应用双边滤波
filtered_image = cv2.bilateralFilter(image, d=9, sigmaColor=75, sigmaSpace=75)

# 显示结果
cv2.imshow('Filtered Image', filtered_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

import cv2
import numpy as np

# 读取图像
image = cv2.imread('path_to_image.jpg')

# 创建遮罩
mask = np.zeros(image.shape[:2], np.uint8)
cv2.rectangle(mask, (100, 100), (400, 400), 255, -1)

# 应用遮罩的高斯模糊
blurred = cv2.GaussianBlur(image, (15, 15), 0)
masked_blur = cv2.bitwise_and(blurred, blurred, mask=mask)

# 反遮罩原图像
mask_inv = cv2.bitwise_not(mask)
result = cv2.bitwise_or(image, masked_blur, mask=mask_inv)

# 显示结果
cv2.imshow('Result', result)
cv2.waitKey(0)
cv2.destroyAllWindows()

import cv2

# 读取图像
image = cv2.imread('path_to_image.jpg')

# 应用调整参数的高斯模糊
blurred_image = cv2.GaussianBlur(image, (5, 5), 0)

# 显示结果
cv2.imshow('Blurred Image', blurred_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
