Abstract

This paper presents a new method to extract areas of interest in drop caps and particularly the most important shape: Letter itself. This method relies on a combination of a Aujol and Chambolle algorithm and a Segmentation using a Zipf Law and can be enhanced as a three-step process: 1) Decomposition in layers 2) Segmentation using a Zipf Law 3) Selection of the connected components.
