Prompt

Apply Bilateral Filter to smooth noise and fine texture inside similar-colored regions while maintaining clearly defined boundaries between contrasting areas. Create clean, gently flattened color fields with intact silhouettes and natural lighting gradients. Avoid edge halos, color bleeding, and uniform defocus. Preserve the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Color areas become smooth, boundaries remain more clearly defined.

Principle

Spatial proximity1 and color similarity determine common filter weights2.

Try it out

Test strong and weak color sensitivity.

Classification

Calculated image processing result.

05 Bilateral Filter, applied to “Full-page portrait of John in gold frame on purple background (NYPL b12455533)”This portrait illustration features intricate patterns and a central figure. Processing removes fine line detail and paper texture but preserves the high-contrast edges of the character.Scan by NYPL (photo); processed for the Atlas · Public domain · Wikimedia Commons
