Sobre IBD

No mundo eletrónico moderno, são desenvolvidos vários tipos de sistemas biométricos. O sistema de reconhecimento da impressão palmar é uma das tecnologias emergentes devido à sua estabilidade, características únicas, dispositivo de captura de baixo preço e velocidade de execução rápida. Proporciona uma grande área para a extração de características. A impressão palmar é constituída por linhas principais, rugas (linhas secundárias) e cristas epidérmicas. Contém outras características, como a textura, os entalhes e as marcas. Estas características podem ser utilizadas para comparar uma impressão palmar com a outra. A principal desvantagem da Transformada de Stockwell (ST) é a quantidade de redundância de informação na sua representação tempo-frequência resultante. A DOST é proposta para melhorar a eficiência computacional da ST. A técnica DOST acelera o cálculo e elimina a redundância no domínio espaço-frequência.
