“…In image multiscale analysis, adaptive (nonuniform) grids for the finite element method applied to the Perona-Malik equation [29] with the modification suggested in [11] were studied in [6] (3D case). In image segmentation and representation (see [23] for a recent account), many algorithms are based on adaptive approaches. Most adaptive methods produce an image segmentation using a variant of the split and merge method [18,41].…”

“…A idéiaé distribuir a massa dada por 1 − β igualmente para todo {Y = y|X = x} e atribuir a massa β a {Y = y|X = x}. Em [Barrera et al, 2006a] [Lizier et al, 2008], foi adotado β = 0.9, o que significa uma confiança de 90% no valor observado.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
