2D Convolution Function
Dear R-Helpers,
I want to try the 2D (two-dimensional) convolution in R.
For example, let us we have the following kernel and data.
kernel <- (1,2,3,2,1)
data <- array(1:100, dim=c(10,10))
I know the function 'convolve' only for one-dimensional convolution, but it
is just for a 1D sequence.
Is there any function for 2D convolution?
For theory, please refer to the following link:
