OpenCV/Python -根据边界框的面积查找异常值

import cv2
import numpy as np

image = cv2.imread('image.jpg')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

edges = cv2.Canny(gray, 50, 150)

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

threshold = 1000  # 设定的面积阈值
for contour in contours:
    area = cv2.contourArea(contour)
    if area > threshold:
        # 这是一个异常值
        # 可以进行相应的处理，如绘制边界框或标记异常区域
        x, y, w, h = cv2.boundingRect(contour)
        cv2.rectangle(image, (x, y), (x + w, y + h), (0, 0, 255), 2)
