Adopting this method, we can not only improve the smoothness of filtering curve but also approximately preserve the shape of original function.
应用这种方法不仅可以改善滤波特性曲线的光滑度，还可近似地保持原函数的形状。
The denoised signal can preserve the edge's location and shape of the original signal, but it is not smooth enough.
贝叶斯估计较好地保留了信号的边缘信息，但滤波信号尚不够平滑。
