Abstract

Abstract: An improved anisotropic smoothing method based on the characteristics of human visual system is proposed.The four-order partial differential information of image is merged into this method to avoid the“blocky effects”，the direction of diffusion is increased and the numerical model is improved.Experimental results show that this method can obtain good results in noise elimination and edge reservation.

Key words: anisotropic diffusion, human visual system, image smoothing

摘要： 在人类视觉系统特性基础上提出了一个改进的各向异性平滑方法。加入图像四阶偏微分信息避免“阶梯效应”，扩展演化方向，改进数值模型。实验结果表明，该方法在噪声消除和边缘保留方面能获得较好的效果。
