In plain words
ThreadTone converts digital images into halftone designs made of thread, automating a manual art process. It processes input images through three main steps to generate patterns that can be recreated on a circular loom using thread. The tool is designed for artists and makers interested in creating portrait-style thread art without requiring extensive manual labor, producing results that use only thread to represent the original image through halftone technique.

Not too long ago I came across a piece of art made by Petros Vrellis . A piece of art that makes the engineer in me scream: automation. As can be seen below Petros uses a circular loom and a lot of patience to develop portraits from thread. Below I’ll quickly go through the steps of automating the process but of course all the credits go to the artist behind this amazing idea! The final result is a halftone representation of an image using nothing but thread. The main idea is comprised of three steps. First a little image pre-processing is done to various input images for threading. Second is some processing done in python to determine where one should place the successive threads as to…from thevelop.nl

Hi HN - this is a little side project I threw together. Some implementation details: image processing is all done with headless GIMP (running inside a Docker container) through its built-in Python API. It's _very_ slow (about 50 seconds/image), and currently it processes exactly one image at a time. The website is built with NextJS; payments are processed by Stripe. I've had the best results with pictures of houses, although certain photos of people or nature can look neat, too. (For example: https://brushify.art/s/ruYmQWk, original photo from…
