Need help in finding Convolutional Neural Network

• Need help in applying these layes on input image (I)
• By using input image (I) I want to check output after fullyConnectedLayer (In the form of matrix or vector).

I=imread('test1.png');

layers = [ ...

imageInputLayer([480 640 3])

convolution2dLayer(5,20)

reluLayer

maxPooling2dLayer(2,'Stride',2)

fullyConnectedLayer(2)];
