Abstract

"SISTEMA E MéTODO PARA OCULTAçãO E RECUPERAçãO DE DADOS SEM PERDAS ROBUSTO DA REPRESENTAçãO DE PEQUENA ONDA DE INTEIRO". A invenção refere-se a um método o qual compreende prover um bloco de coeficientes de IWT (transformada de pequena onda de inteiro) para de preferência uma sub-banda de alta freqüência de uma imagem; determinar um valor médio dos ditos coeficientes dentro do dito bloco; e estabelecer um valor médio codificado para incorporar um, de um valor de bit 0 lógico e um bit 1 lógico no dito primeiro bloco.
