我只想从意味着活动轮廓的图像（脑肿瘤MRI图像）中分离出肿瘤

Question

只有肿瘤是白色的，而另一部分是黑色的。如何计算肿瘤面积？我使用Windows作为操作系统和python3。如何计算大脑面积？

#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，只需使用cv2.imread（“ brain.png”）

Answer 2

尝试一下：

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

或

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

Answer 3

然后尝试此操作，导入argparse并进行设置。
