Normalize image

[Thilina27]

Hi

Im trying example CNN with Nvidea Digits and im new to caffe.  

I have a data set of 100*100 gray scale image and i need to normalize them before use in CNN 

In python i have preform this 

  X_test -= X_test.mean()

  X_test /= X_test.std()

Is there a way to add a layer in Caffe to preform this task ? 

like this 

• layer {
    name: "concat"
    bottom: "in1"
    bottom: "in2"
    top: "out"
    type: "Concat"
    concat_param {
      axis: 1
    }
  }
