Hi everybody,

I've been tasked with creating a landscape dotted with buildings, out of a hand-drawn bitmap of an area.

To keep it simple let's imagine the picture has a black background and just two sets of symbols: yellow triangles for houses and red circles for buildings (but eventually there will be more symbols and colors).

How do I convert those hand-drawn symbols into coordinates that I can then use in Houdini to place the correct models for each category?

At this point I'm considering it a computer vision problem and I'm thinking of using a python node taking advantage of some kind of external python library to categorize the shapes, find their bounding boxes and out of the centroids generate a list of points with a category attribute.

Is there an easier way?

Kind regards, Manu
