为此采用全样本对称周期延拓的方法进行边界延拓。
Therefore, full-sampled symmetric periodic extension method is adopted here in order to alleviate boundary effect.
图像的边界延拓我们采取周期延拓或对称延拓方式，图像压缩的数字实验验证了算法的优良性。
We use period extension or symmetry extension in image processing. Our arithmetic has perfect properties that validated by numeric experiments in image compression.
