摘要我们提出了一种快速和缓慢的信号后处理方法，用于消除阈值和量化过程中出现的伪影。我们使用小波作为工具来定义约束和变分泛函作为信号复杂性的度量。该方法来自不同的可能性混合变分和小波多分辨率的方式，似乎是自然的分析。
Abstract We propose methods of both slow and rapid post-processing of signals for erasure of artifacts that arise in the process of thresholding and quantization. We use wavelets as tools to define constraints and variational functionals as measures of complexity of signals. The methods come from analyses of different possibilities of blending variational calculus and wavelet multiresolution in ways that appear to be natural.
