【摘要】 在灰色系统、小波分析以及中值滤波去噪理论的基础上,提出基于灰关联的小波、中值滤波的综合模型改进算法,并用MATLAB编程实现了遥感影像去噪处理,使得去噪后均方根误差相对于改进前减低,信噪比相对于改进前提高,改进效果明显,说明改进方法是一种有效的去噪方法。更多还原

【Abstract】 Based on the grey system and Wavelet Analysis and the median filter denoising theory,it designs a model which combined with wavelet,median filtering and Grey system for image de-noising.The remote sensing image denoising was realized by MATLAB programming,relative to denoising RMS error improved obviously decreases,and signal-to-noise ratio increases relative to the improved obviously,improve the effect is obvious,shows that improved method is an effective method for noise reduction.更多还原
