• James G ☛ Create an automated image collage with computer vision

  For a while, I have been taking photos of new mugs I buy. I used to keep an up-to-date list on my mugs page but as with many things that seldom need updated, the list became out of date. This got me thinking about new ways I could present the mugs I own; methods that could be a bit more interactive. I thought about creating a collage of all my coffee mugs in a single image.
