如何在像素输出中找到区域

Question

我需要以像素为单位输出二进制摩尔的面积

mole_1 = mpimg.imread('mole_1.png')
gray_mole = rgb2grey(mole_1)
threshold = skimage.filters.threshold_otsu(gray_mole)
binary_mole = (gray_mole < threshold)

下面是我用像素表示的区域

trys = np.sum(binary_mole == 255)
print('number of white pixels = ' , trys)

二元摩尔看起来像

我该如何解决这个问题

Answer 1

有一个名为regionprops的内置函数，它有许多度量

import skimage.measure as meas
binary_label = meas.label(binary_mole)
measurements = meas.regionpros(binary_label)

area = measurements[0]['area']
