    abstract     = {Summary: This paper contains the theoretical mechanisms of the techniques for non-convex shape recognition, through the use of contour chains and differentiated weighting scheme on them. As an application example, we use a set of digital images that represent the various symbols contained in the dactylogical alphabet. First we introduce the reader to the many pre-processing and segmentation techniques applied to the set of images. Later on, we describe the use of direction codes to code the symbols' contour. Finally, a novel differentiated weighting scheme is incorporated to an ALVOT-type algorithm, and then used for the supervised classification (identification) of the various symbols within the image set. The proposed methodology is then evaluated and contrasted through a series of experiments.},
