我只想将肿瘤从(脑肿瘤MRI图像)图像中分离出来，这意味着活动轮廓。

Question

只有肿瘤是白色的，另一部分是黑色的。我如何计算肿瘤的面积？我用的是windows操作系统和python3，怎么也能算出大脑面积呢？

#Active Countour

image = cv2.imread(args["brain.png"])
shifted = cv2.pyrMeanShiftFiltering(image, 21, 51)
cv2.imshow("Input", image)

gray = cv2.cvtColor(shifted, cv2.COLOR_BGR2GRAY)
thresh = cv2.threshold(gray, 0, 255,
    cv2.THRESH_BINARY | cv2.THRESH_OTSU)[1]
cv2.imshow("Thresh", thresh)
its show:

  File "F:/Semesters/Thesis/New folder (2)/brine.py", line 157, in <module>
    image = cv2.imread(args["brain.png"])

NameError: name 'args' is not defined

Answer 1

cv2.imread只需要文件名，使用cv2.imread("brain.png")即可

Answer 2

试试这个：

image = cv2.imread("\brain.png")

或

image = cv2.imread(r" your full path")

Answer 3

然后尝试一下，导入argparse并设置它。
