To be straightforward: A filter is a collection of kernels, although we use filter and kernel interchangeably. Example: Let's say you want to apply P 3x3xN filter to a K x K x N input with stride =1 and pad = 0. So each of the 3 x 3 matrix in 3 x 3 x N filter is a kernel. And your output will be K-2 x K-2 x P .
