multiplications but we slide this kernel over the input we perform DG convolutions along the width and DG convolutions along the height and hence D G cross DG convolutions over all so the number of multiplications in the convolution of one kernel over the entire input f is DG square times D K square times M now this is for just one kernel but if we have n such kernels which makes the absolute total number of multiplications become n times D G square times D K square times M multiplications let's now take a look at
