Hierarchical representations are ubiquitous in morphological image processing and are mathematically modeled as ultrametric spaces. In this talk, morphological operators for functions defined on ultrametric spaces are considered. The notion of ultrametric structuring function is introduced. Then, using as fundamental ingredient the convolution in the (max,min)-algebra, the multi-scale ultrametric dilation and erosion are defined and their semigroup properties are stated.
