The main contributions are summarized as follows:1. Proposed an integrated denoising algorithm based on mid-value filtering and wavelet transform of fingerprint image.
主要工作如下：1。提出了一种基于中值滤波与小波变换的指纹图像去噪方法。
2
Based on the integral inequality and other quality proved, the paper discusses the conclusion of the mid-value in theorem of integration mean which is got in open interval.
在证明了定积分不等式等性质的基础上，给出并证明了积分中值定理的中值在开区间内取得的结论。
3
The impact of sampling time on concentration of collected bacterium, fungus particles and mid-value diameter of particle number are studied by ANDERSEN bioparticle sampler in lab.
