Hi every one: I want to do some region analysis for 2d/3d block. I saw the
skimage.measure.regionprops is very powerful. But if we can add some feature
1. I want to got every 3d block's surface area. The regionprops's area
for 3d object meas volumn and the perimeter is only2d, I think the method
skimage to cound perimeter works for 3d surface, binary_outline it then
convolve with a 3*3*3 weight matrix. Another function is march_cubes, it
returns a series of face and normal vector, but if we can return a index or a
lable array, to indicate which faces are in a same block?
2. I see the regionprops is based on pixels analysis, and in some feature,
wo must to copy a new image, I think we can do some work by vector. We can
count many feature by contours (except the one need intensity_image).
