How to calculate layer size after convolution in Convolutional Neural Networks?

Question

Mathematics

There is an array of size A . Next, this array is convolved with step B and C filters, each of size D . How can you express the size of the array in terms of all these parameters after the convolution operation has been performed?

Answer 1

int out_sx = (int)Math.Floor((prevBlock.SizeX + pad * 2.0 - coreBlock.SizeX) / stride + 1);
int out_sy = (int)Math.Floor((prevBlock.SizeY + pad * 2.0 - coreBlock.SizeY) / stride + 1);

Block = new Block(out_sx, out_sy, coreBlock.Depth);
