Abstract

"MéTODO DE CODIFICAçãO DE IMAGEM POR WAVELET E MéTODO DE DECODIFICAçãO CORRESPONDENTE". A presente invenção refere-se a um método para codificar uma imagem possuindo uma malha hierárquica associada à mesma, compreendendo a codificação por wavelet. De acordo com a presente invenção, um método de codificação envolve o uso de pelo menos dois tipos de wavelet, que são aplicados de forma seletiva a diferentes áreas da imagem.
