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 below:

    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).
