Can someone tell me if the "Orientation" property has been extended to multiple dimensions?<br> <br> I'm essentially looking a various blobs in a 3d voxel volume, and I'd like to measure their Major axis direction in this 3d space. If the latest MATLAB regionprops can't do this natively, can someone suggest a function/tool that can? A cursory search of the file exchange hasn't yet turned up anything...<br> <br> Thanks,<br> Sven
