Merge two adjacent BinaryRegions

[tomasmanu]

Hi there!
I'd like to merge two binary regions into only one binary region (the reason why I want that is that the two regions correspond to the same object which gets divided because of another object that covers it in the setup).

I found a MergeBinaryRegions node and an AverageBinaryRegion node but I couldn't find the way to use them. My workflow looks like this:

My first thought was to obtain the corners of each BinaryRegion so that I can get the big binary region by adding the coordinates of the corners, but I don't know if it's possible. Because of that I thought of the MergeBinaryRegions and the AverageBinaryRegion nodes. I would really appreciate it if you suggest how can I proceed to merge those regions. I want to obtain the big BinaryRegion because I want to calculate its centroid and then use it to calculate Heading direction.
Any help would be appreciated.
Cheers,
Tomás

Hey Tomas!

MergeBinaryRegions is used to merge two collections of ConnectedComponents, not to merge single binary regions. It takes a Tuple of two ConnectedComponentCollections .

AverageBinaryRegions might work given what you are describing, but you should add it right after SortBinaryRegions. After you use Concat you are effectively flattening the Collection into a sequence of its single elements.

Hope it helps,
Bruno

Hi Bruno!
I tried using AverageBinaryRegions after SortBinaryRegions but nothing gets displayed in the first one:

How can I make it work?

I don't think the visualizer will work since there are a few missing fields. However the centroid should be correct.
