How can i change the connectivity in regionprops from 8 to 4?

I want regionprops to divide the regions with connectivity 4 instead 8. With 8 it mix two region i want separated into one.

regionprops() itself always uses 8 connectivity for 2D arrays.

The way you get around this is to use bwlabel() or bwconncomp() to do the labeling for you, telling them which connectivity you want, and then pass the result to regionprops as a labeled image instead of as a binary image.
