Fix low-contrast images for vectorization
If the subject blends into the background, vectorization becomes noisy and unreliable. Contrast drives clean edges.
Symptoms
- Edges look fuzzy or broken
- Random holes appear in the output
- Cut lines drift or look uneven
Root causes
- Low separation between subject and background
- Soft lighting or blur
- JPEG artifacts
How Lumekon fixes it
- Normalizes raster inputs before tracing
- Builds clean outlines from stronger edges
- Outputs cut and backing shapes for production
Best input tips
- Increase contrast before upload
- Use flat colors instead of gradients
- Avoid blurry or noisy sources
FAQ
Why does low contrast cause bad SVGs?
Vectorization can’t find stable edges when contrast is weak.
Can Lumekon fix low-contrast images?
It helps by preprocessing, but better input always gives better output.
What format works best?
PNG with sharp edges and a clean background.
