Mathematical Morphology and Morphological Neural Networks for Multivalued Data


Mathematical morphology is a nonlinear theory with applications in image processing and analysis. A neural network whose neurons perform elementary operations of mathematical morphology is called a morphological neural network. Such as traditional neural networks, morphological neural networks can be used for classification and regression.In this research project, we aim to contribute by developing morphological operators for multi-valued images. Particular attention will be given to morphological operators obtained using a supervised reduced order. We will also address the uncertainties that arise in natural images as well as the vagueness in describing the values of a multi-valued image.As a straightforward application of the results obtained for multi-valued mathematical morphology, we intend to develop morphological neural networks for multi-valued data. Neural networks for multi-valued data represent an active research topic and include, for example, hypercomplex neural networks and capsule networks. In particular, we plan to investigate complete lattice projection autoassociative memories which, besides the low computational cost and theoretical simplicity, presented promising results in face recognition problems.
