CNN Layers: high pass filters and truncation layer

I would like to create two layers for my CNN design where the input image is high-pass filtered via convolution with 16 (4 × 4) high-pass DCT filters, and then a Truncation layer (Truncation Linear Unit) activation function.

These layers are not built in matlab deep learning toolbox. How can I make them?

Thank you in adavance!

You can write your own Custom Layer using Deep Learning Toolbox in MATLAB. To get started you can refer to Define Custom Deep Learning Layers & Deep Learning Custom Layers.
