### Introduction

This app offers you a new way to modify your photos. It allows you to change the aspect ratio of your images with minimal visual artifacts. Important content, like people or landmarks, can be preserved while parts of the background might get stretched or cropped.

### Background

This application was developed in the Bachelor Thesis of Daniel Graf at ETH Zurich. It implements and extends the axis-aligned image retargeting algorithm by Panozzo et al.

This thesis was supervised by Dr. Daniele Panozzo and Prof. Dr. Olga Sorkine-Hornung at the Interactive Geometry Lab at ETH Zurich. The underlying optimization problem is solved using CVXGEN, a project by Jacob Mattingley at Stanford. The icon of the app was designed by Felix Hornung.

The source code of this application is freely available on our github repository. To find out more about the techniques used to implement this application, we refer you to the Bachelor Thesis or ask you to contact us with any questions you might have.
