## It's just a line...

A continuous line illustration is a type of drawing consisting of a single line. Although relatively simple, these illustrations possess a unique charm that captures the heart of whoever sees them.

In this project we introduce a method for automatically generating a continuous line illustration from an input image by making use of image processing techniques and concepts in graph theory.

Our approach essentially consists in inferring a graph based on a set of extracted image contours and finding a path that traverses through all edges of a Semi-Eulerized version of the graph.

Moreover, our approach also allows us to control the amount of detail shown in the final illustration to some degree.
