[英]How to find area in pixels output
I need to output the area in pixels for the binary_mole.我需要 output binary_mole 的像素区域。
mole_1 = mpimg.imread('mole_1.png')
gray_mole = rgb2grey(mole_1)
threshold = skimage.filters.threshold_otsu(gray_mole)
binary_mole = (gray_mole < threshold)
My attempt to find the area in pixels is below我试图以像素为单位查找区域如下
trys = np.sum(binary_mole == 255)
print('number of white pixels = ' , trys)
The binary_mole looks like binary_mole 看起来像
How do I fix this or go about it?我该如何解决这个问题或关于它的 go?
There is a built in function called regionprops, that has numerous measurements.有一个内置的 function 称为 regionprops,它有许多测量值。
import skimage.measure as meas
binary_label = meas.label(binary_mole)
measurements = meas.regionpros(binary_label)
area = measurements[0]['area']
