Amazing algorithms for image processing [closed]

Question

I have recently came across a great image processing algorithm called Seam Carving. It uses graphs (Shortest Path algorithm) to do its job.

What other amazing algorithms are out there worth looking at?

I'm not talking about the majority of boring matrix based ones, rather something you could never think about before you came across it, just like this one.

Answer 1

Even though this is offtopic I'm going to answer ;)

In this page you can find algorithms which:

• Depixelize an image
• Color a black and white image
• Restore a picture or make a HDR (whatever that means...)
• Turn a photo into an hand-drawn like image
• Seam carving
• Remove objects
• Compose a picture
• Beautify a face
