我想在一个大于某个阈值的区域的每个闭合轮廓周围绘制一个边界框,而不仅仅是最大的轮廓.我该怎么做呢？到目前为止,这是我尝试过的:

contours, _ = cv2.findContours(thresh, cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)
for c in contours:
    rect = cv2.boundingRect(c)
    if rect[2] < 100 or rect[3] < 100: continue
    print cv2.contourArea(c)
x,y,w,h = cv2.boundingRect(c)
cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
cv2.putText(im,'Moth Detected',(x+w+10,y+h),0,0.3,(0,255,0))
cv2.imshow("Show",im)
cv2.waitKey()  
cv2.destroyAllWindows()
