提出了一种与现有广义Hough变换(GHT)不同的识别破碎图形的方法.称为特殊广义Hough变换(SGHT)方法.该方法在参数表制作阶段和识别阶段,都与现有GHT方法不同.理论分析和实验的结果表明,采用SGHT方法, 可以解决常规GHT方法难以识别破碎图形的困难,且有很高的配准精度和速度,既可用于破碎图形的识别也可用于非破碎图形的识别,具有普适、快速和准确的特点.

This paper proposes a 8-neighborhood based generalized Hough transform (SGHT) method developed from the existing generalized Hough transform (GHT) method. The difference chiefly shows in the process of generating the Reference-Table and recognizing the graphics. The new method resolves the difficulty in the process of recognizing fragmented graphics from images by conventional GHT, which can be employed not only in the un-fragmented graphics recognition but also in the fragmented graphics recognition with significant precision and rapidity. The effectiveness of ENHT has been proved in our experiments.-
