metadata.name: dc.description.abstract
metadata.value: The article considers digital processing of image series using the discrete systems. The
  problem of displacement field calculation for image sequences is presented. The mathematical
  model based on discrete optimization is proposed as its solution. The model reflects the
  discrete nature of image series acquisition. It also takes into account the intensity change
  along the system trajectories. The study of integral-type functional on the trajectories
  ensemble of the discrete system was performed, and the optimization algorithm for
  displacement field construction based on its results was designed. The analytical form of
  functional variation is obtained and the functional gradient is derived, which allows us to
  use directional optimization methods to find the required parameters. The algorithm can
  be used in digital image processing, in particular, in nuclear medicine imaging. The method
  example implementation for nuclear medicine image processing is considered.
