一种新的低空间分辨力阵列触觉图象的处理方法

A New Processing Methoe for Low Spatial Resolution Arrayed Tactile Image

本文根据低空间分辨力阵列触觉图象的特点，分析了噪声来源、形式和分布，提出了一种新的基于平滑的噪声消除方法。讨论了在图象基本顶点的基础上，运用了顶点分裂和合并技术找出相应的图形顶点，并通过最小二乘法复原出离散图象的连续轮廓，从而为提高触觉图象辨识率奠定了基础．

This paper analyses the noise source,type and distribution according to the characteristicsof low spatial resolution arrayed tactile image and presents a new method of removing the noise bysmcothing.Then,on the basis of searching out the basic vertexs of the image,it discusses the ways tofind out the vertexs of the object and to recover the continuous boundary of the discrete tactile imageby using least square method and vertex-splitting and merging technology. Therefore,it lays thefoundation for raising the recognition of tactile image.
