Otimização de Filtros de Aguçamento para a Melhoria da Qualidade de Imagens Magnificadas
Keywords: Sharpening, Interpolation, Laplace filter, LUM filter, BNF filter
AbstractSimple interpolation methods are computationally efficient and rather effective for magnification from low-resolution into higher resolution images. However, blur and undesirable visual artifacts in the resulting images are often produced. This work evaluates the effect of optimized sharpening filters applied to magnified images.
