Red Eye Removal

AI-powered detection and correction of red eye caused by camera flash.

API Endpoint

POST /api/v1/tools/red-eye-removal

Processing: Asynchronous (returns 202, poll /api/v1/jobs/{jobId}/progress for status via SSE)

Model bundle: face-detection (200-300 MB)

Parameters

Parameter	Type	Required	Default	Description
file	file	Yes	-	Image file (multipart)
sensitivity	number	No	50	Red eye detection sensitivity (0-100). Higher values detect more subtle red-eye
strength	number	No	70	Correction strength (0-100). How aggressively to neutralize red
format	string	No	-	Output format (optional override)
quality	number	No	90	Output quality (1-100)

Example Request

curl -X POST http://localhost:13490/api/v1/tools/red-eye-removal \
  -F "[email protected]" \
  -F 'settings={"sensitivity":60,"strength":80}'

Notes

• Requires the face-detection model bundle to be installed (200-300 MB).
• First detects faces, then locates eye regions within each face, and finally identifies and corrects red-eye pixels.
• The facesDetected count indicates how many faces were found; eyesCorrected is the total number of individual eyes that had red-eye corrected.
• Output is always PNG for maximum quality preservation.
• Supports HEIC/HEIF, RAW, TGA, PSD, EXR, and HDR input formats via automatic decoding.
