Project name

Image retargeting by k-seam removal.

Project short description

This project presents a methodology for content aware image resizing based on seam removal. In this work four different approaches were implemented in order to retarget an image:

• removing a 8-connected path of pixels (1-seam) minimizing an energy function
• removing a not connected path of pixels (k-seam) minimizing an energy function
• removing a 8-connected path of pixels (1-seam) minimizing the energy variation in the image
• removing a not connected path of pixels (k-seam) minimizing the energy variation in the image

where k is the maximum disconnect allowed.

The work ends with a comparison on several test pictures among these algorithms considering the one which gives the best results.

Part 2: project description

State of the art

This project is based on the article Shai Avidan, Ariel Shamir, Seam Carving for Content-Aware Image Resizing, ACM SIGPLAN, 1994, in which the author describes content aware image resizig by removal of 8-connected path of pixels.

Think about what you would have liked to find clearly explained when you started your work, instead of discovering it all by yourself the hard way.
