In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.

在匹配过程中，以向量之间夹角的大小作为相似度度量，直接利用图像的灰度信息在高维向量空间中考虑图像之间的相似度，克服了在低照度、低信噪比的图像中求边缘、角点、梯度和形状等特征的困难，不受向量模大小以及向量平移的影响，即相似度的计算是线性光照不变的。

Based on scale SVD transform, a target feature extracting method is proposed to solve this difficult problem. The experimental result shows that this method has favorable stability to target matrix's SVD feature vectors, and high invariant property to displacement, rotation and scale.

Owing to the approximate and detail coefficients at each level after decomposition using undecimated wavelet transform have the same length as the original signal, the transform can possess time invariant property and retain more characteristics in time domain, and therefore improve the effect of denoising.

由于非降采样小波分解后的各层系数和原始信号的长度均相同，因此在具备平移不变性的同时还能保留更多的时域信息，从而可以提高信号的降噪效果。
