This is a simple design of the Gaussian kernel source code.
这是一个简单的高斯核设计源代码。
The function performs the downsampling step of the Gaussian pyramid construction. First, it convolves the source image with the kernel.
该函数执行高斯金字塔结构下采样的步骤。首先，它与内核的源图像进行卷积。
Advantage of the proposed algorithm is that any source can be separated, whether it is super-Gaussian or sub-Gaussian signal.
该算法可以对任意源信号进行分离，而不管它是超高斯还是亚高斯信号。
