bwboundariesmex inside bwboundaries

Hi all,

I am exploring bwboundaries function to find out the behind detailed algorithm, so that I can make changes to fit my requirements. However, I encountered a sub-function called bwboundariesmex used by bwboundaries. What is the algo of that function? There does not seem to be any document about it.
Can anybody explain to me the main algos behind bwboundaries and bwboundariesmex?

One more question, is there a way for Matlab to communicate with powerpoint? Or to produce slide shows using Matlab as in Powerpoint?

The scenario is I am building a system to auto-correct the distorted slide shows projected on the panel, captured by webcam.

Thank you in advance.

Ken.

You can use the OfficeDoc utility to produce PowerPoint slides from Matlab: http://www.mathworks.com/matlabcentral/fileexchange/15192-officedoc-readwriteformat-ms-office-docs-xlsdocppt

I'll give it a try.

Thanks Altman:-)

How about first question on bwboundariesmex and bwboundaries?

Call the Mathworks and ask them.
They will usually tell you the published paper that they used (if they
used one) as the basis for the algorithm. They won't give you the
course code though.
Maybe you might want to take a look at bwtraceboundaries also.
