| 摘 要： | 为减少定阶灰度腐蚀运算中对权重α的限制,提出用面积编码技术对定阶灰度结构元素(0,α, 1)进行编码,采取非相干相关器加电子取阈的方法实现定阶灰度腐蚀,对取阈器件的分辨率要求降低了.

| Abstract: | To reduce the restriction in ordered gray scale erosion, the area encoding technique is used to code three gray scale structural element . The ordered gray scale erosion is performed through an optical incoherent correlator with electrical threshold, in which the resolution requirement of the thresholding device is much reduced. |
