如何以像素為單位查找區域 output

Question

我需要 output binary_mole 的像素區域。

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

我試圖以像素為單位查找區域如下

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

binary_mole 看起來像

我該如何解決這個問題或關於它的 go？

Answer 1

有一個內置的 function 稱為 regionprops，它有許多測量值。

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

area = measurements[0]['area']
