Query: A Compact Graph Model of Handwritten Images: Integration into
  Authentification and Recognition   A novel algorithm for creating a mathematical model of curved shapes is
introduced. The core of the algorithm is based on building a graph
representation of the contoured image, which occupies less storage space than
produced by raster compression techniques. Different advanced applications of
the mathematical model are discussed: recognition of handwritten characters and
verification of handwritten text and signatures for authentification purposes.
Reducing the storage requirements due to the efficient mathematical model
results in faster retrieval and processing times. The experimental outcomes in
compression of contoured images and recognition of handwritten numerals are
given.
