trabalho apresentam resultados satisfatórios. Eles se espalham pela imagem, devido ao baixo contraste existente entre a íris e a esclera.
5.2 TRABALHOS FUTUROS
Os resultados obtidos neste trabalho permitem que novas pesquisas sejam desenvolvidas, entre elas sugerem-se:
• Adaptação do método PP–AC para realizar a segmentação da íris, tornando o processo completo;
• Estudo de técnicas para identificação e remoção de cílios, pálpebras e outras fontes de ruído;
• Integrar ao PP–AC uma técnica para identificar e restaurar cílios;
• Uso de técnicas de segmentação de contorno ativo para não mais restringir as formas das bordas de pupila e íris;
• Uso de contorno ativo para detectar pálpebras;
• Aplicar os métodos propostos a novas bases de dados;
• Estudos em bases de imagens de câmeras com pouca resolução como webcam e/ou câmera de celular;
• Investigar esquemas que usem mais de um filtro para codificar os padrões de textura da íris, assim como diferentes métodos de aprendizagem de máquina para obter melhor classificação;
• Estudo dos melhores bits existentes nos templates que formam o iriscode, o que possibilitaria a criação de representações ainda mais compactas, com os bits mais discriminativos, esperando melhores resultados.
