question about source code

[liupengkd]

in convolution.cpp
"const int kernel_extent_w = dilation_w * (kernel_w - 1) + 1;
const int kernel_extent_h = dilation_h * (kernel_h - 1) + 1;"
dilation_w 和 kernel_extent_w变量指代的是什么意思？
“ else if (pad_w == -233 && pad_h == -233)
{
int wpad = kernel_extent_w + (w - 1) / stride_w * stride_w - w;
int hpad = kernel_extent_h + (h - 1) / stride_h * stride_h - h;”
这段代码的含义是什么？

作为初学者，我对卷积参数的理解
w1=(w0+2pad-kernel_size)/stride+1;
h1=(h0+2pad-kernel_size)/stride+1;

may get your answer about dilated convolution in google :)
