基于小波阈值去噪算法的研究作者：聂真真来源：《科教导刊》2011年第od调查18期 摘要分析研究了小波阈值去噪的特点，在软硬阈值折中法的基础上提出了一种改进的阈值函数，该阈值函数不仅易于计算，而且具有优秀的数学特性和清晰的物理意义。仿真结果表明，该方法无论在主观视觉效果上还是在客观评价指标上均明显优于常用的软阈值、硬阈值及软硬阈值折中法，图像质量得到明显提高，体现了该方法的有效性和优越性。 变量之间的关系 关键词 硬阈值 软阈值 酷派n68软硬阈值折中法 阈值函数

AbstractAnalysis studied wavelet threshold denoising characteristic , proposed one new method based on hard and soft threshold method.function.This threshold function is not only easy to computation, but also has excellent mathematical characteristics and clear physical meanings. The results show that this improved method is on whether in subjective visual effect in objective evaluation indexes or were significantly better than the commonly used soft threshold, hard threshold and the soft and hard thresholding compromise method, image quality are improved obviously, reflect the effectiveness of the method and the superiority.
