The NLMeans filter, originally proposed by Buades et al., is a very popular filter for the removal of white Gaussian noise, due to its simplicity and excellent performance. The strength of this filterdoi:10.1007/978-3-642-17691-3_5Bart Goossens...

Kalman Filter与RLS的区别 1.估计准则 常用的估计准则包括:无偏估计:即假设状态的估计值与真实值的平均值相等。 最小二乘估计:不考虑数据的统计特性,如期望,方差等,直接用最小二乘法得到最优估计。 误差方差最小:在满足最小...) 这种方法使用估计值和真值的误差的平方和作为cost function,然后cost function对估...

This paper combines threshold operatoion in nonsubsampled contourlet domain with non local means filter for image denoising in the compressed sensing framework. The experiment results show that NSCT-NLmeans based algorithm outperformes the other multi-resolution and multi-directional transforms in ...
