@MuhongGuo Are you still interested in pushing a PR?

I just take a look at the code and @xq198109 is right This marks the point visited https://github.com/PointCloudLibrary/pcl/blob/cd99687bd1f332d77aee06a8e9fbad4fb08c0a44/filters/include/pcl/filters/impl/local_maximum.hpp#L161-L167 And this skips those points without adding them to the result https://github.com/PointCloudLibrary/pcl/blob/cd99687bd1f332d77aee06a8e9fbad4fb08c0a44/filters/include/pcl/filters/impl/local_maximum.hpp#L122-L125...

I've been very busy lately, it would be great if @ArkaprabhaChakraborty can work on this
