WATCH THE SOURCE-SHARPNESS EXPERIMENT
Coloring Page Maker: Blurry Source Experiment
Watch three matching sailboat illustrations with different input blur, and see why output density cannot restore missing source contours.
What this video shows
All three inputs measure 600 × 400 pixels. Added blur radii are 0, 4 and 12. The current public tracing functions ran with Clean Outline in Node. The displayed traces are actual code outputs; browser decoding, page export and printers were not tested.
Read the experiment and inspect the input and output files, or open the coloring page maker.
