Abstract

resumo da patente de invenção para: "aumento de amostragem e melhoramento de sinal". sinal que se pretende melhorar qualitativamente sofre frequentemente de degradação de qualidade na região de alta frequência espacial mais do que comparando com a região de baixa frequência espacial. assim, melhora-se a qualidade eficientemente através da combinação do sinal por melhorar qualitativamente com uma parte de alta frequência extraída a partir de uma aproximação esparsa do sinal que se pretende melhorar qualitativamente.
