Member Function Documentation

template<class T, class T1>

void region_growing< T, T1 >::extract_region_indices ( )

private

extract region_indices from cloud

template<class T , class T1 >

void region_growing< T, T1 >::filter

(

)

simply runs the algorithm

Step 0 check if we are ok to run the algorithm

STEP 1 Create an empty queue indice list

STEP 2 Create a kdtree representation of cloud input

STEP i Create a bool vector with the indice points processed

STEP 3 Let's make a fisrt search on all seed points

STEP 4 The queue list will be all the points on region_indices in the begining

STEP 4.1 Make a search on each point and check what points are already processed and if not add it to queue list

4.1.2 For each neighbor found do the following

4.1.3 Check if the point is already processed and if not added to queue list

Setup flags and reset pointers
