本文给出了DOG小波变换像空间的再生核函数的具体表达式及等距恒等式,并利用再生核函数的结构对DOG小波变换的像空间作出了具体的描述,使得对其像空间的形成有了更直观和更深刻的认识.这既为一般小波变换像空间的描述奠定了基础,又为该小波变换的实际运用提供理论依据.
用DOG函数进行边缘检测的硬件网络模型
边缘检测 DOG函数 网络模型
2008/12/5
根据视觉计算理论,如果用一组不同大小的运算子对成象在视网膜上外界场景的二维图
象进行光强度变化的检测可以获得原始图象的零交叉表象,即原始要素图.本文在讨论这一
方法的基础上,提出了一种基于DOG函数的网络模型.模型满足了空间平移不变性,可实时
并且平行地对输入信号进行边缘检测.模型中引入了时间维来构成尺度空间的零交叉表象的
