我只想将肿瘤与（脑肿瘤 MRI 图像）图像分离，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。如何计算肿瘤面积？我用windows做操作系统，python3，脑面积怎么计算？

#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")

Answer 2

试试这个：

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

或

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

Answer 3

然后试试这个，导入 argparse 并设置它。
