Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。

Mineralizing fluid migrated, concentrated and allocated in the fractured zone between granite and metamorphic rock, it was a good canal for Rn, U, Tb and K, added intense sericitization, in geophysical exploration we found that y -ray spectrometry, Radon spectrometry can reflect the allocation of fractured zone, X-ray fluorescence analysis in laboratory can effectively find alteration envelope, elements geochemical abnormality, soil primary and secondary halo, then find deposits allocation.

结合矿床特征，以核技术为主的找矿方法中γ能谱及氡测量能很好地反映容矿破碎带及花岗岩与变质岩的接触位置，室内多元素X射线荧光测量技术可以有效寻找蚀变带、元素地球化学异常及土壤原生晕、次生晕等流体成矿地球化学界面的标志，快速追踪矿床的位置。

The singular values of the project can be used as the character vector. The singular values of the scaling invariant can be obtained by the statistical characteristics of Radon transform. Since the singular values of the matrix are uncorrelated with the position of the column or the row of the matrix. In this way, the character vector of singular values with shift, scaling and rotational invariant is arrived at by this algorithm.

针对各颜色分量，利用Radon变换的奇异值的统计特性提取了具有尺度不变性的奇异值，由于矩阵的奇异值分解具有旋转不变性，因此该奇异值为平移、尺度和旋转不变的特征向量。
