使用opencv python从图像中提取多个ROI

import cv2
import numpy as np

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

roi_coordinates = [(x1, y1, width1, height1), (x2, y2, width2, height2), ...]

rois = []
for (x, y, width, height) in roi_coordinates:
    roi = image[y:y+height, x:x+width]
    rois.append(roi)

for i, roi in enumerate(rois):
    cv2.imshow('ROI {}'.format(i+1), roi)

cv2.waitKey(0)
cv2.destroyAllWindows()
