Nettet20. sep. 2024 · borderType: 像素向外逼近的方法，默认值是BORDER_DEFAULT,即对全部边界进行计算。 该函数使用于任意线性滤波器的图像，支持就地操作。 当其中心移动到图像外，函数可以根据指定的边界模式进行插值运算。 函数实质上是计算kernel与图像的相关性而不是卷积： int borderType = BORDER_DEFAULT; int borderIsolated = borderType & BORDER_ISOLATED; int borderIsolatedDest = borderType & ~BORDER_ISOLATED; What is " borderType & BORDER_ISOLATED " means? And what's the differences between with and without tilde? Is it a Destructor?
