Seam Carving
I remember seeing a demonstration of this during a keynote at Adobe MAX in Barcelona, in 2008 maybe? I&#x27;m fuzzy on the year, but I do remember there being an air of excitement around this feature in particular – it seemed like magic! Since then I&#x27;ve learned how the algorithm works, and it&#x27;s beautifully simple to the point where I can&#x27;t believe it wasn&#x27;t discovered long before.<p>I particularly like how it can be composed with other algorithms (face detection has been mentioned) to change the energy function and make it even smarter. It&#x27;s one of those things you can implement in a weekend and have a lot of fun with.<p>Kudos to everyone involved in developing this!
