Euclidean Paths are an alternative to vectorization techniques for representing the boundary of discrete objects. The general model of the Euclidean paths provides a "semi-continuous" representation of discrete 8-connected boundaries. We recall the construction of a family of Euclidean paths (the tangent driven Euclidean paths) which gives a good approximation of the real boundary underlying a discrete boundary. We then present how this can be used for some geometrical transformations of scanned characters.
