真空吸尘器噪声能量等级测定方法 - The time - domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ) , capturing virtually all of the signal but rejecting most of the noise
对相关函数进行时域滤波,挑选出互相关函数中窄信号自相关函数部分,去掉剩余的大部分噪声能量,得到加窗互相关函数( ccf ) 。 - Stochastic resonance ( sr ) is different from traditional methods ( such as correlation , equality superposition , filter etc ) in faint signal detection . sr can turn parts of noise energy into signal energy and enhance signal while wiping off noise , so that increasing the signal - to - noise rate ( snr )
随机共振检测技术与传统的弱信号检测方法(如相关、平均叠加或滤波等)不同,它可以把部分噪声能量转换成信号能量,实现增强信号能量的同时去除噪声,从而提高了信噪比。 - On one hand , from the technique of constrained least squares and limited energy of additive noise , an effective restored approach by adopting regularization method to overcoming ill - posed problem , solving an equation with a single variable , and using space iterative algorithm is proposed ; on the other hand , aiming at the restoration of blurred image , another effective restoration approach based on least - square algorithm is also proposed in this paper . this method firstly adopts increment iterative algorithm to improve convergence and meanwhile applies regularization technique to overcome ill - posed problem . in the computations , the regularized parameter has its adaptive character , which can be determined in terms of the restored image at each iteration step therefore automatically correct to the appropriate value
一是从约束最小二乘出发,在加性噪声能量有界的前提下,采用正则化方法来克服病态问题,通过解一个单变量方程,并利用空域迭代运算实现了一种有效的图像复原;二是针对模糊图像的复原问题,从最小二乘算法出发,采用增量迭代的方法改善算法的收敛性,同时结合正则化技术克服问题的病态性质,并引入自适应的正则化参数,使其与图像复原的迭代运算同步进行并自动修正到最优值。
