| Abstract(in English) | Partitioned Iterated Function Systems that are called PIFS, encode an image using a property of fractal in the image. Therefore, PIFS is a kind of fractal image coding. PIFS partitions the original image into some blocks that are called range blocks. The range blocks are assigned so that they do not overlap with each other. For each range block the most similar block, that is called domain block, is searched in the contracted image. The image is encoded by the correspondences of the range blocks to the domain blocks. Although fractal image coding is expected the high compression rate. searching the optimal domain block to each range block has been required large computational costs. Therefore, we propose a new coding method using Self-Organizing Maps for classifying range blocks and domain blocks. By classifying the range blocks and domain blocks the computational costs are decreased. This method can decrease the computational costs in comparison to the original PIFS though it keeps the image quality almost the same with that of the original PIFS. |
