Description: A new approach for fingerprint verification, based on wavelets and pseudo Zernike moments (PZMs), is
discussed. PZMs are robust to noisy images, invariant to rotation and have a good image reconstruction
capability [4]. PZMs have been used for global analysis and so they are used to extract global features (the
shape of the fingerprint image). Wavelets are good at local analysis and so they help to extract local
features (minutiae) from a fingerprint. Therefore, this hybrid approach extracts most significant features
from the fingerprint images and achieve better verification rate. Different types of wavelets are used for the
study but the result shows that Symmlet orthonormal wavelet of order 8 gives best verification rate.

Description: 使用维单尺度离散小波变换，通过迭代进行对低频进行单尺度离散小波分解，也可以达到对原图像进行多尺度分解的目的。而且若使用二维单尺度离散小波变换，各个系数的提取以及单支重构都有matlab现成的函数，很容易进行操作。唯一存在的问题是当避开二维多尺度离散变换函数，试图利用二维单尺度离散小波变换函数dwt2对每次分解后得到的低频系数不断进行处理时，在某些小波基的情况下会造成重构的失败。-Using the dimension discrete wavelet transform, the discrete wavelet transform is used to decompose the low frequency single scale discrete wavelet transform, and the multi scale decomposition of the original image can be achieved. And if the use of two-dimensional discrete wavelet transform, the coefficients of the extraction and single branch reconstruction have matlab off the shelf function, it is easy to operate. The only problem is when avoid two-dimensional multi-scale discrete transform function to using two-dimensional single scale discrete wavelet transform function dwt2 low-frequency coefficients of each decomposition continuous processing. In some wavelet bases will cause reconstruction failure.
