Previous issue date: 2006-12-18 / We propose a multi-resolution, coarse-to-fine approach for stereo matching, where the first matching happens at a different depth for each pixel. The proposed technique has the potential of attenuating several problems faced by the constant depth algorithm, making it possible to reduce the number of errors or the number of comparations needed to get equivalent results. Several experiments were performed to demonstrate the method efficiency, including comparison with the traditional plain correlation technique, where the multi-resolution matching with variable depth, proposed here, generated better results with a smaller processing time / Para acelerar o rnatching em sistemas de vis?o est?reo ? proposta uma abordagem multi-resolu??o, coarse-to-fine, variando a profundidade do nivel inicial para cada pixel da imagem. A t?cnica proposta tem o potencial de atenuar diversos problemas do algoritmo com profundidade constante, tornando possivel reduzir o n?mero de erros ou o n?mero de compara??es necess?rias para obter resultados semelhantes. Para demonstrar a efici?ncia do m?todo, foram realizados v?rios experimentos, incluindo compara??o com a t?cnica tradicional de correla??o simples, na qual o rnatching usando imagens em multi-resolu??o com profundidade vari?vel obteve resultados superiores com um menor tempo de processamento
