Computer aided restoration of handwritten character strokes
Abstract
© 2017 Elsevier Ltd This work suggests a new variational approach to the task of computer
aided segmentation and restoration of incomplete characters, residing in a highly
noisy document image. We model character strokes as the movement of a pen with a varying
radius. Following this model, in order to fit the digital image, a cubic spline representation
is being utilized to perform gradient descent steps, while maintaining interpolation
at some initial (manually sampled) points. The proposed algorithm was used in the
process of restoring approximately 1000 ancient Hebrew characters (dating to ca. 8th–7th
century BCE), some of which are presented herein and show that the algorithm yields
plausible results when applied on deteriorated documents.
