Seam carving: content-aware image resizing … in JavaScript

Oleksii Trekhleb has implemented the Seam Carving algorithm in JavaScript.

With this article I want to do three things:

  1. Provide you with an interactive content-aware resizer so that you could play around with resizing your own images
  2. Explain the idea behind the Seam Carving algorithm
  3. Explain the dynamic programming approach to implement the algorithm (we’ll be using TypeScript for it)

Using the algorithm it’s possible to resize an original image (center) without distorting important features in the image (left) unlike regular resizing which squeezes the image (right).

Using the resulting JS Image Carver you can see the algorithm in action.
