    • Partition coding using multi-grid chain code and motion compensation 

      Marqués Acosta, Fernando; Gasull Llampallas, Antoni (IEEE, 1996)
      Conference report
      Open Access
      In this paper, a lossy partition coding technique is presented which leads to decoded partitions with unnoticeable losses. It uses a hexagonal grid for contour representation and it is based on the concept of multi-grid ...
    • Predicció de la demència tipus Alzheimer mitjançant xarxes neuronals a partir de dades cognitives
