Abstract :
A local signal analysis represents the properties of a signal on selected bounded domains. In the one-dimensional case, the local signal analysis can be based on orthogonal projections which are related to the subdivision into intervals. The multidimensional situation is more difficult to analyze. Some ideas of how to transfer the one-dimensional case to the multidimensional one are considered, replacing intervals by polytopes. As an example, the hexagonal subdivision of the two-dimensional space is treated
