Abstract	This paper aims at demonstrating the viability in the use of parallel distributed computing to improve the image processing. Image processing techniques were implemented in the sequential and parallel way using the Java language and the parallel virtual libraries mpiJava and JPVM. A algorithm that executes the median filter was implemented and processed with different size of masks. From the results it was possible to make a comparison between the sequential and parallel implementation, and show that the gain using parallel distributed computing depending on the amount of data to be processed. Resumo. Este artigo tem como objetivo demonstrar a viabilidade da melhoria no tempo de execucao de algoritmos utilizados para o processamento de imagens atraves do uso da computacao paralela distribuida. Tecnicas de processamento de imagens foram implementadas de forma sequencial e paralela, utilizando a linguagem Java e as bibliotecas de trocas de mensagens mpiJava e JPVM. Foi implementado o algoritmo filtragem mediana, sendo executado com diferentes tamanhos de mascaras. A partir dos resultados obtidos foi possivel construir uma base de comparacao entre a implementacao sequencial e a paralela, e mostrar que o ganho de desempenho obtido com o paralelismo dependendo depende da quantidade de dados a ser processada.
