摘要: 概论一个图象识别系统的核心部分是预加工和特征提取．先滤掉干扰，然后提取图象特征．因此，系统必须处理某一特定灰度下的二值矩阵，以便提取特征．“R2-3-4”算法的过程采用简单的逻辑结构划分矩阵，对曲边区域进行边缘跟踪，把各区域的外边缘置2，内边缘置4，区域内部置3，来提取特征，然后进行子块拼接．Abstract: The R-2-3-4 algorithm introduced in this paper is simple in logic.It can follow the contour of the curved region in the two-value matrices in order to extract certain features.The main function of the algorithm is to plot the region contour on the x-y plotter and display certain parameters,such as perimeter and area,quickly.
