请问需要对以下代码进行优化：

def get_postion(image):
    img = cv2.imread(image)
    blurred = cv2.GaussianBlur(image,(5,5),0,0)
    canny = cv2.Canny(blurred,0,100)
    contours,hierarchy=cv2.findContours(canny,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
    print(len(contours))
    for contour in contours:
        x,y,w,h = cv2.boundingRect(contour)
        area = cv2.contourArea(contour)
        loop = cv2.arcLength(contour,True)
        if 152<loop<162 and 1444<area<1849:
            x,y,w,h = cv2.boundingRect(contour)
            cv2.rectangle(image,(x,y),(x+w,y+h),(0,0,255),2)
            cv2.imwrite("111.jpg",image)
            return x
    return 0

还请提供一些更具体的优化需求和背景信息，这样我才能更好地为您提供帮助。
