疎らな分布を持つ空間情報データの画像表現の圧縮についての検討
仵 小軍・北原正樹・清水 淳(NTT)
To achieve quick querying or interactive visualization of large spatial data, using image representation as data container is considered as an efficient approach. Based on such approach, to improve data compressing ratio, we propose an algorithm by utilizing several image compression methods adaptively, according to the sparseness of the data. The effectiveness of the algorithm is shown by some experimental results.
