Description: This demonstration illustrates the application of adaptive filters to signal separation
using a structure called an adaptive line enhancer (ALE). In adaptive line
enhancement, a measured signal x(n) contains two signals, an unknown signal
of interest v(n), and a nearly-periodic noise signal eta(n). The goal is to remove
the noise signal from the measured signal to obtain the signal of interest. Platform: |

Description: 由于自适应滤波器组的频率响应匹配于信号的统计特性,所以能够得到更为有效的信号分解. 文中根据信号的统计特性,按照低通子带能量最大化的原理设计自适应滤波器组. 结合自适应滤波器组和传统的阈值方法,得到一种更为有效的去噪方法. 实验结果表明,与相同长度的标准滤波器相比,新方法得到了更大的信噪比改善.-Adaptive filter banks as a result of the frequency response to match the statistical properties of the signal, it can be more effective decomposition of the signal. According to the statistical properties of signals, in accordance with the low-pass sub-band energy to maximize the principle of the design of adaptive filters. combination of adaptive filter and the traditional threshold methods, to be a more effective de-noising method. The experimental results show that the standard with the same filter length, the new methods to improve signal to noise ratio greater. Platform: |

Description: In the existing bilateral filtering algorithm, the domain parameters and range parameters need to
be predefined. Parameters of a bilateral filter are fixed and cannot guarantee to be optimal. A new adaptive
bilateral filtering (ABF) is proposed in this paper. The ABF obtains the domain parameters by estimating
the local object scale to minimize edge blurring. The range parameters are set adaptively according to noise
variance estimated in smooth areas of a sub image. The method can improve the filtering performance. To
filter out strong noise, the value of domain parameters is increased. ABF avoids setting parameters solely
by experience, and the domain parameters are set adaptively according to the local image features. ABF
can improve the noise filtering ability and reserves edges. Experiments show that the adaptive bilateral filter
is superior to traditional bilateral filters, anisotropic diffusion filters, and modified bilateral filters in both
subjective and objective uations.-In the existing bilateral filtering algorithm, the domain parameters and range parameters need to
