摘　　要：小波变换在图像的多分辨分解应用中的一个关键技术是克服有限长小波变换中的边缘效应。提出了一种解决有限长小波变换中边缘效应的方案，并在理论上证明了本方案能彻底消除边缘效应。A key technique in multiresolution image decomposition using wavelet transform is to overcome the boundary effects in finite length wavelet transform. In this paper, a method of eliminating the boundary effects is introduced. The method proves in theory that it can eliminate the boundary effects completely. Experimental results also indicate that this method is excellent.

关 键 词：小波变换 边缘效应 分解 合成 图像处理
