Remove Overlappaed Points by Points' Magnitude

This code removes the overlapped points within radius < threshold value by using k-D tree.

A Zipped file has eight files which are related to Demo2D.m and Demo3D.m. The Demo2D removes the points in 2D-space and also find out non-overlapped points in their strongest magnitude order. The Demo3D does it in 3D-space. The core file is remove_overlapregions_kd.m. Furthermore we used k-D tree(http://www.mathworks.com/matlabcentral/fileexchange/4586-k-d-tree, Guy Shechter) to find out close points at given point. It gives us so good performance.

The function remove_overlapregions_kd() has three paramters as follows:
1. ovpeak - points which have a important last column(magnitude column) for sorting in descend order.
2. threshold - radius to get near points(euclidean distance)
3. fpnum - the userdefined maximum number of non-overlapped points(But, a default value becomes infinity(Inf))

NOTE THAT: For compiling mex files you should run MEXCOMPLIE.m invovled in the attached zipped file.
