在图象的传输过程中 ,我们希望尽可能减少传输的数据量。基于小波分析的金字塔分解和重构的方法 ,由于必须保留图象的平滑部分 ,数据量并没有明显减少。本文以严格的理论为依据 ,提出了仅利用细节部分实现图象重构的方法 ,不但可以实现图象的无损变换 (分解 )及反变换 (重构 ) ,而且由于仅利用细节部分实现图象重构 ,因此数据值和冗余度都小。
In the image transmission process, we hope to minimize the amount of data transmitted. Based on the pyramid decomposition and reconstruction methods based on wavelet analysis, the amount of data is not significantly reduced due to the need to preserve the smooth part of the image. Based on the strict theory, this paper proposes a method to reconstruct the image by using only the detail part, which not only can realize the non-destructive transformation (reconstruction) and the inverse transformation (reconstruction) of the image, but also realize the image Reconstruction, so data values and redundancy are small.
