Region Analysis using point cloud data

Hello, I have the following issue.
I have a point cloud fetched from a Kinect. With this point cloud I would like to do a region analysis in order to find a specific object or to exclude objects. In order to do this I guess the best function would be “bwconncomp”.
First question: Is there a function to transform the point cloud into a 3d binary array in order to use “bwconncomp”?
Second question: Or do I have to program an algorithm on my own to get the 3D binary array?
Third question: Is there another/better approach to do a region analysis for 3D problems?
Thanks in advance

Hi Jürgen,
I understand that you are interested in performing region analysis on Kinect point cloud data.
The "bwconncomp" function and other Image Processing Toolbox functionality are probably not the best tools for performing this kind of analysis. There actually are 3-D Point Cloud Processing tools in MATLAB's Computer Vision System Toolbox.
If you have access to this toolbox, I would take a look at this documentation and see if any of the examples and functions seem appropriate for your data and desired task.
I hope this helps.

Hi Jürgen I got the same problems about segmenting the point clouds into connective clusters for a week without solution.did you solve it? would you like to help me?or share me the matlab code to study? Thanks in advance!
