SEGMENTATION AND UNFOLDING OF ELONGATED POINT CLOUD DATA
 
ABSTRACT:
Interpreting 3D point cloud data is like trying to color inside the  lines of a shape but most of the lines are missing. This talk looks segment a shape represented by unorganized point cloud surface data into 'inside' and 'outside' regions using information provided by localized principal component analysis. After we discover which areas of a shape are inside, we then discover the medial axis of a shape for the purposes of `unfolding' that object. We conclude with example images produced by our algorithm.
 
BIOGRAPHY:
James Church has been in graduate school far too long. He received his undergraduate degree in Computer Science at the University of Tennessee at Martin and a M.S. in Computer Science at the University of Mississippi. The work presented in this talk was published as a book chapter in the 12th IEEE/ACIS International Conference in Niigata, Japan. James defended his PhD Prospectus on November 8th 2013.
