import cv2 import matplotlib.pyplot as plt import cvlib as cv import urllib.request import numpy as np from cvlib.object_detection import draw_bbox import concurrent.futures

url='http://192.169.1.4/cam-hi.jpg' im=None

def run1(): cv2.namedWindow("detection", cv2.WINDOW_AUTOSIZE) while True: img_resp=urllib.request.urlopen(url) imgnp=np.array(bytearray(img_resp.read()),dtype=np.uint8) im = cv2.imdecode(imgnp,-1)

    bbox, label, conf = cv.detect_common_objects(im, confidence=0.6, model="yolov3-tiny")

    print(bbox, label, conf)

    im = draw_bbox(im, bbox, label, conf)

    cv2.imshow("live transmission",im)
    key=cv2.waitKey(5)
    if key==ord('q'):
        break

cv2.destroyAllWindows()
