Resumo

O objetivo deste projeto é o desenvolvimento de algoritmos, técnicas matemáticas e ferramentas de software para problemas de computação visual, baseadas em conceitos de aproximação matemática. Computação visual inclui geometria computacional, modelagem geométrica, síntese de imagens e animações, visualização científica, visão computacional, codificação e processamento de imagens e reconhecimento de padrões. Por aproximação matemática entende-se a substituição de um fenômeno real ou modelo matemático complexo por um modelo mais simples ou mais eficiente, com garantias teóricas ou experimentais sobre os erros decorrentes dessa substituição. Os sub itens específicos deste projeto refletem a experiência acumulada e as idéias originais dos membros nas grandes áreas acima mencionadas, e oferecerão muitas oportunidades de sinergia e cooperação.
