import image
import sensor
import ai

sensor.reset()
img = sensor.snapshot()

def loop():
    img.draw_rectangle((1429,162,250,140), color=(0,255,0), thickness=4)
    thr = (120,159,90,117,104,156)
    blobs = img.find_blobs([thr],roi=(1429,162,250,140))

    for ln in blobs :
        img.draw_rectangle(ln.rect(),color=(255,0,0), thickness=4)
