In order to discern slowly varrying weak anomalies on a background of noise field and to deal with problem like limiting the instability of the solution due to high-frequency magnification of errors in the series of calculations such as the downward-continuation of potential field, this paper discusses the designing principles of an optimum linear digital filter in the least square sense. This may be transformed into the mathematical problem, namely how to select the optimum filtering function in the space of the L2 linear normed function. It would be very complicated and difficult, if the problem is to be solved directly in the space domain. We found that it may be mathematically much simplier and more rigorous, if we should directly select the trnasfer function or the wave-number response of the optimum linear filter in the wave-number domain by using the method of isoperimetric problem in calculus of variations. In this way, the expression of the transfer function of the selected optimum linear filter is quite simple, namely,L(f,k)=|Si(f, k)|2/{|Si(f,k)|2+λ|Ni(f,k)|2}where|Si(f,k)|2 and |Ni(f,k)|2 express the energy spectra (or the power spectra) of the filter input signal and noise respectively; f, k are wave numbers on the x and y directions.In regard to the above-mentioned two types of the problem and the two related optimum linear filters, the expressions of L(f,k) are the same. They differ only in the conditions of selecting the parameter (λ).After setting up the theoretical expression of the transfer function L(f,k) of the optimum linear filter, we should be able in the least square sense to examine various linear filtering methods, so far published in foreign and domestic literatures in solving the above-mentioned two types of the problems and to show that the optimum results of the linear filtering can be achieved theoretically for different signal and noise conditions. Thus, it provides theorectical criterion for designing two-dimensional linear digital filters.For the observed results of the harmonic functions of potential fields, the above theory can be applied easily to the designing of optimum linear digital filters, but only in the approximate manner.

针对如何在干扰场的背景上区分出低缓异常,以及在位场的向下延拓一类计算中如何限制因误差的高频放大所导至的解的不稳定性等问题,本文探讨了在“最小二乘”意义下的最佳线性数字滤波器的设计原理,并将它转化为下述数学问题,即在L_2线性赋范函数空间中如何选取最佳滤波函数的问题。在空间域中直接解这个问题是十分复杂和困难的,我们发现在波数域中用变分法中的等周问题的解法直接选取最佳线性滤波器的传输函数(或波数响应),则在数学方法上既简单又严格。这样选取的最佳线性滤波器的传输函数L(f,k)其表达式也很简单,即L(f,k)=|S_i(f,k)|~2/{|S_i(f,k)|~2+λ|N_i(f,k)|~2}。式中,|S_i(f,k)|~2及|N_i(f,k)|~2分别代表滤波器输入端讯号和干扰的能谱(或功率谱),f、k分别代表x、y方向上的波数,λ为大于零的常数。 对上述两类问题以及相关的两种最佳线性滤波器而言,L(f,k)的表达式是相同的,而区别仅在于其参变量λ的选取条件不同而已。 有了最佳线性滤波器的传输函数L(f,k)的理论公式,就可以在最小二乘的意义下分析和评价国内外所发表的解决上述两类问题的各种线性滤波方法,并能指出在不...

The lateral inhibitory network was studied as a spatial digital filter. When the distribution function of the inhibitory coefficient is Gaussian, the network isnotonly a filter which suppresses the lower spatial frequency components and thus enhancing the contrast, or a higher frequency pass filter, but it is also an inverse Gaussian filter which can recover the image blurred by the random disturbance in the medium, thus enhancing contrast and raising the 'signal-noise ratio'.The difference...

When the distribution function of the lateral inhibition coefficient is Gaussian, the nonrecurrent inhibition network can not be an inverse Gaussion filter. In general, to possess the same given transfer function, fewer lateral branch interconnections and a simpler distribution of the lateral inhibition coefficient are needed for a recurrent network than for a nonrecurrent one, so that the recurrent inhibitory network can be constructed or regulated more easily.

本文从空间数字滤波器的角度研究了侧抑制网络的功能。当侧抑制系数是高斯分布的情况下,侧抑制网络不仅仅是抑制空间低频分量而提高反差的滤波器,也不仅仅是空间高通滤波器,它还可能是一种逆高斯滤波器,具有使因随机媒质干扰而变模糊的图象恢复清晰的作用,从而提高了图象的反差,提高了“讯噪比”。另外,本文讨论了循环抑制网络和非循环抑制网络的区别。在侧抑制系数都是高斯分布的情况下,非循环抑制网络不能起到逆高斯滤波器的作用。就一般的情况而言,要达到某种相同的频率响应函数,循环网络较之非循环网络只需较少、较短的侧枝联结,侧抑制系数的分布也较简单,从而循环抑制网络便于结构和调节。
