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.
