A transformada wavelet na fusão de imagens de sensoriamento remoto

Abstract

No sensoriamento remoto, o desenvolvimento dos sistemas sensores e inerente ao fornecimento de dados com maior quantidade, qualidade e variabilidade, fazendo do processamento digital de imagens um meio para aplicação de m etodos matem aticos que aprimoram os resultados já obtidos. Uma característica dos sistemas sensores e a resolução espacial de imagens pancromáticas superior a resolucão espacial das imagens multiespectrais. Uma característica dos sistemas sensores e o fornecimento imagens pancromáticas com resolução espacial superior as imagens multiespectrais, cuja fusão busca melhor resolução espacial com menor perda do conteúdo multiespectral. Existem inúmeros métodos de fusão de imagens bem conhecidos, dentre os quais podemos elencar IHS, YUV e métodos baseados em transformadas multiescala. Os méetodos tipo IHS baseados na transformada wavelet têm gerado excelentes resultados na busca por minorar a distorção das cores no resultado do processo de fusão...

In remote sensing, the development of sensor systems is inherent in the provision of data with greater quantity, quality and variability, making the digital image processing a way for an application of mathematical methods to improve the results already achieved. A feature of the sensors systems is to provide panchromatic images with a better spatial resolution than its multispectral images, whose merger preserves spatial details without multispectral content loss. There are numerous widely known fusion methods, among which we can list IHS, YUV and mustiscale transform based methods. IHS type methods based on wavelet transform has generated excellent results in the search for minimizing color distortions in the merger... (Complete abstract click electronic access below)
