Description
Painterly is an application that "paints" input images stroke by stroke to produce digital paintings. GenAI is not used in any part of the production pipeline.There is a free demo available under Releases on the GitHub repo.Let me know what you think!

Could you build this?
Partial Building a standard desktop or web wrapper is trivial, but the core stroke-based non-photorealistic rendering (NPR) algorithm requires specialized computer vision and optimization math.
What it would actually take: A real implementation uses C++ or Rust with OpenCV or custom shaders executing greedy stroke placement, gradient vector fields, and color error minimization algorithms (e.g., Hertzmann's painterly rendering or simulated annealing). The difficult part is tuning stroke dynamics, brush textures, and multi-scale difference maps to produce aesthetically pleasing strokes without prohibitive compute times.
