Seam Carving
|
|
============
|
|
|
|
This example demonstrates how images can be resized using seam carving [1]_.
|
|
Resizing often distorts contents in the image. Seam carving tries to resize
|
|
images while trying to keep important content intact. In this example we are
|
|
using the Sobel filter to signify the importance of each pixel.
