Secondary title: | Lossless and near-lossless raster image compression based on PNG filters |
Secondary abstract: | A lossless and near lossless raster image compression are presented in this thesis. The algorithm first predicts values using PNG filters on the whole picture. A simple hevristics is implemented to deterime which filter to choose. BWT and MTF transformations are applied to achieve better data compression. Finnaly, the Huffman coding is used for actual data compression. Output file sizes are compared with GIF and PNG formats. |
