Applied build — internal engineering work

This is internal engineering and R&D work, not a client project. It is published to show technical depth — the modelling, evaluation, and tooling behind the AI automation we build for clients. No client is associated with it.

A deep-learning pipeline that transforms human face sketches into full-colour, photo-realistic images using a Generative Adversarial Network. The generator maps sketches to RGB photos while the discriminator refines realism, trained on paired sketch-photo datasets in PyTorch.

Objectives

  • Train a GAN to reconstruct photo images from sketch input.
  • Use L1 loss + adversarial feedback for better image fidelity.
  • Generalize across validation images with normalized training data.

Process

  • Pair grayscale sketches with their RGB photos via a custom dataset loader.
  • Generator: encoder–decoder CNN (3 conv + 3 deconv, BatchNorm, ReLU, Tanh).
  • Discriminator: CNN with LeakyReLU on the 4-channel sketch+photo input.
  • Train with BCE adversarial loss + L1 pixel loss (Adam), 100 epochs.

Results

  • Generated realistic faces capturing structure, contours and lighting.
  • Side-by-side per-epoch visualization tracked convergence.

What we took from it

  • Combining pixel-based and adversarial objectives sharpens output.
  • Conditioned GAN training and data normalization are key to fidelity.
