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。
The feasibility and effective of the multi-radial mid-value filtering have been verified through some model data tests and suppressing the surface wave in the practical pre-stack seismic data.
通过模型资料测试，以及近地表反射地震实例叠前资料面波压制试处理研究工作，验证了多线束径向中值滤波方法的可行性和实用性。
