No. of bitstreams: 1 Fernando Jorge Cutrim Demetrio.pdf: 680959 bytes, checksum: 8bfd83d8940d01500dfe55ffeccc7148 (MD5) Previous issue date: 2005-04-01 / This work describes the development of an algorithm for visualization of compressed volumetric data with a local cosine transform scheme, that minimizes the blocking artefacts generated by transform compression methods, and makes possible the visualization of large volume data in computer with limited memory resources. We also present the results obtained for the visualization process . / Este trabalho descreve o desenvolvimento de um algoritmo para visualização de dados volumétricos comprimidos baseado na transformada do cosseno local, que minimiza os artefatos nos blocos gerados pelo método de compressão, e possibilita a visualização de grandes volumes em computadores com recursos limitados de memória. Nós apresentamos também os resultados obtidos pelo processo de visualização.
