Abstract Morphological levelings are powerful operators and possess a num-ber of desired properties for the construction of nonlinear scale space image representations. In this paper, a comparison between levelings constrained by different multiscale markers namely, reconstruction openings, alternate sequential, isotropic and aniso-tropic diffusion filters was performed. For such a comparison a relation between the scales of each marker was established. The evaluation of the simplified images was performed by both qualita-tive and quantitative measures. Results indicate the characteristics of each scale space representation
