For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.
为了减小小波变换山区格网DEM数据压缩中边界失真区域,将山区格网DEM高程值视为广义坐标下的离散随机序列,把二维离散小波变换中的边界问题转换为一维离散小波变换中的边界问题,不仅大大减少了小波变换边界失真区域,提高了重构DEM数据边界点的精度,而且减少了边界补零个数,提高了压缩比;通过对山区格网DEM数据小波变换低频区和高频区变换系数分布特点的分析,采取了霍夫曼—游程混合熵编码方案,设计了高效、低失真的"自适应硬阈值"量化器,即对低频区变换系数不进行量化,直接进行霍夫曼编码;对高频区变换系数则先用"自适应硬阈值"方法量化处理,再进行游程编码。
