WebNov 26, 2024 · The weights of the convolutional layer for this operation can be visualized as the figure above. In the figure it can be seen how the 5x5 kernel is being convolved with all the 3 channels (R,G,B) from the input image. In this sense we would need the 5x5 kernel to have weights for every single input channel. nifty movement history
