【摘要】 给出基于数学形态学操作实现符号替换及Ｈｏｕｇｈ变换的光电装置。着重讨论了用收缩和膨胀来实现符号替换的操作过程。同时，把Ｈｏｕｇｈ变换看作是符号替换的特例，并对此进行了数值模拟，给出了实验验证结果。更多还原

【Abstract】 Based on mathematical morphology,an opto-electronic system to perform symbolic substitution and Hough transform is pro-posed in this paper,The operation processing of implementing sym-bolic substitution using erosion and dialation is emphatically discussed.Accortding to the definition, Hough transform can be regarded as a special case of symbolic substitution,Its numerical simulations and experimental verification are also given.更多还原
