OpenCV图像处理篇之边缘检测算子
3种边缘检测算子灰度或结构等信息的突变位置是图像的边缘,图像的边缘有幅度和方向属性,沿边缘方向像素变化缓慢,垂直边缘方向像素变化剧烈。因此,边缘上的变化能通过梯度计算出来。一阶导数的梯度算子对于二维的图像,梯度定义为一个向量,Gx对于x方向的梯度,Gy对应y方向的梯度,向量的幅值本来是 mag(f)?=?(Gx2?+?Gy2)1/2,为简化计算,一般用mag(f)=|Gx|+|Gy|近似,幅值同时...

ARM板ok6410移植qt4.84+opencv2.4.9初步成功
先上图,有图有真相,当课题重新回归到嵌入式搭载的老问题上时,我还一度各种担心,发现最新的A9板4412能用Android了,还想着偷懒买块现成的只做最顶层开发就好,结果找遍工业相机厂家没见到有提供Android驱动的,一了解才明白,Android驱动是基于linux驱动的貌似,于是乎,又尝试着回归到移植opencv到嵌入式linux的老路上来。 想当初,零linux基础的我对着借来的6410...
