使用Python OpenCV查找模糊对象周围的紧密轮廓

import cv2
import numpy as np

image = cv2.imread('image.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray, (5, 5), 0)

edges = cv2.Canny(blur, 30, 150)

contours, _ = cv2.findContours(edges, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

min_area = 100
filtered_contours = [cnt for cnt in contours if cv2.contourArea(cnt) > min_area]

cv2.drawContours(image, filtered_contours, -1, (0, 255, 0), 2)

cv2.imshow('Contours', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
