Effecient ways to merge blob whose position inside another blob using cvbloblib

I basically want to remove all blobs whose positions insides another blobs.

image description

I use the cvbloblib . I can get all the blobs; however, the library basically detect all blob even the position of those blob inside another.

I think of using iterative ways to detect if each blob inside another and merge them together.

for (int i = 0; i<res.getnumblobs(); i++){="" for="" (int="" j="0;" i<res.getnumblobs();="" i++){="" find="" if="" each="" blob="" is="" inside="" another="" if(condition="" blob(i)="" inside){="" delete="" break="" or="" return="" to="" another="" blob(i+1)="" }="" }="" }<="" p="">

However there are some issues :

  1. iterative ways is not effecient way

  2. we you see in the image above, there are the cases where a blobs insides not 1 but could be another N blobs. so I tend to think about recursive function to do that.

Do you have any ways to merge those blobs inside ?
