Image cropping tutorial: Examples and ideas for creating better composition |

Abstract The work is about a method for cropping photographs given minimal information about the location of important content, provided by visual attention. The system should use visual saliency data such as [1] (or any of the effective and recent methods cited in [2]) to identify important content and compute the best crop for any given aspect ratio or size, enabling applications such as automatic snapshot recomposition, adaptive documents, and thumbnailing. A proposal for cropping is given in [3] for in a general optimization framework that facilitates adding new composition rules, as well as adapting the system to particular applications.
