WebA 1x1 convolution is actually a vector of size f 1 which convolves across the whole image, creating one m x n output filter. If you have f 2 1x1 convolutions, then the output of all of the 1x1 convolutions is size ( m, n, f 2). So a 1x1 convolution, assuming f 2 < f 1, can be seen as rerepresenting f 1 filters via f 2 filters.
