在python中实现局部平均速度过慢的图像缩小

import cv2
import numpy as np

image = cv2.imread('image.jpg')

scale_percent = 0.5  # 缩小比例为50%
kernel_size = 5  # 卷积核大小为5x5

width = int(image.shape[1] * scale_percent)
height = int(image.shape[0] * scale_percent)
dim = (width, height)

resized_image = cv2.resize(image, dim, interpolation=cv2.INTER_AREA)

blurred_image = cv2.blur(resized_image, (kernel_size, kernel_size))

cv2.imshow('Original Image', image)
cv2.imshow('Resized Image', resized_image)
cv2.imshow('Blurred Image', blurred_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
