Using Metal Performance Shaders for RealTime Fast Style Transfer.

Style Transfer

Fast Style Transfer

  • We have to generate dataset using Style Transfer algorithm from photos and train neural network
  • We have to using sequence of Residual blocks for approximate style.

Python Code for Style Transfer :

iOS and iPhones

Metal Performance Shaders

Setup Metal stack for Rendering

  • Need ability load PyTorch weights into Convolution and InstanceNorm layers
  • Need implement Concatenate operation for ability implement Residual layer
  • Need implement Multiply for ability run multiply operation on constant value on final step.

Load PyTorch Weights:

  • Convolution Layer — main Neural Network layer for image processing and computer vision.
  • Instance Normalization — layer for increase training speed, scale data between layers and doing regularisation, was specially created for Fast Styling. (The Missing Ingredient for Fast Stylization)
  • RELU — activation function for increase training speed and filtering train direction in appropriate way.
  • Upscale — Upscale image, but in combination with Convolution Layer works better then “Transposed convolution Layer”
  • Concatenate(+) operation Metal Performance Kernel
  • Multiply(×) operation Metal Performance Kernel
