| 摘 要： | 针对4种传统阈值函数的共同不足,联系到脉冲噪声可由函数仿真模拟,又由函数的特殊性,对传统的4种阈值函数分别做了改进.仿真实验结果显示:所做改进不仅可以除去高斯白噪声,而且可以除去脉冲噪声.

| Abstract: | In this paper,four kinds of traditional threshold function of the common lack of impulse noise may be linked to the simulation function.By the specificity of function,four kinds of the traditional thresholding function are improved respectively.Simulation results show that the improvement can remove Gaussian white noise and impulse noise as well. |
