摘要

为了快速检测二值图像上的任意形状，提出了一种利用光栅运算(bitblt)硬件执行霍夫变换原理的方法，并配有工作站。图像位图之间的布尔运算用于搜索与给定形状相对应的候选模式。使用bitbit硬件，这些操作可以快速执行。该方法不仅适用于形状识别，也适用于线条检测

Fast shape detection using Hough transform by raster operation

To detect arbitrary shapes on a binary image quickly, a method is developed for performing the principle of the Hough transform by means of the raster operation (bitblt) hardware, with which a workstation is equipped. The Boolean operations among bitmaps of images are used to search candidate patterns corresponding to a given shape. Using the bitblt hardware, those operations can be carried out rapidly. The method is applicable not only for shape recognition but also line detection.<>
