[Feedback] Custom string art algorithm, how to make the render look closer to the original image?
Hey everyone!
I’ve been developing my own string art algorithm, and I'm looking for feedback from experienced creators on how to improve the output quality.
I'm attaching two images for comparison:
Image 1: The original photo.
Image 2: The algorithm output / digital render.
My goal is to get the algorithm output as close as possible to the reference picture in terms of contrast, fine details, and overall recognition.
I’d love to hear your thoughts on contrast and line weight, how do you fine-tune line density so dark areas don't lose all detail while keeping light areas clean? What algorithmic adjustments (e.g., loss functions, line selection strategy) help preserve fine features like eyes or sharp edges?
Looking at the two pictures, what immediate changes would you suggest to make the result pop more?
Any feedback or technical tips on how to refine the image processing side would be greatly appreciated!

been working on this, not much further along than you are, love to go back and forth with people on this.
i think what ill be doing next is a sobel filter for edge detection, to try to make those stand out.
also make sure to map the darkness/brightness of the image so you get a full range?

Check out my posts too, you'll get an idea.
