Active contours network to straighten distorted text lines

We introduce a new method to straighten text lines. The general approach consists of using an active contour network based on an analytical model. First, we propose a method based on Bezier curves; then we present a model that requires cubic B-splines which leads to more accurate results. Finally, we propose to automate the initialization by using an approach based on a particle system. The proposed methods are illustrated on real images of curved text
