Description: Digital maps can best stored and distributed electronically using compressed raster image formats.We introduce as to rage system for the
map images that supports compact storage size,decompression of partial image,and smooth transitions between various scales.The main
objective of the proposed storage system is to provide map images for real-time applications that use portable devices with low memory and
computing resources.Compact storage size is achieved by dividing the maps into binary layers,which are compressed using context-based
statistical modeling and arithmetic coding.Partial image decompression is supported by tiling the image into block sand implementing direct
access to the compressed blocks.In this paper,we give overview of the system architecture,describe the compression technique,and discuss
implementation aspects.Experimental result sare given both in terms of compression ratio sand image retrieval timings. Platform: |

Description: The optimal predictors of a lifting scheme in the general n-dimensional case are obtained and applied
for the lossless compression of still images using rst quincunx sampling and then simple row-column
sampling. In each case, the e ciency of the linear predictors is enhanced nonlinearly. Directional post-
processing is used in the quincunx case, and adaptive-length postprocessing in the row-column case. Both
methods are seen to perform well. The resulting nonlinear interpolation schemes achieve extremely e cient
image decorrelation. We further investigate context modeling and adaptive arithmetic coding of wavelet
coe cients in a lossless compression framework. Special attention is given to the modeling contexts and
the adaptation of the arithmetic coder to the actual data. Experimental evaluation shows that the best of
the resulting coders produces better results than other known algorithms for multiresolution-based lossless
image coding.
