How this service works
Find near-duplicate images. Computes perceptual hash distance between two image URLs to detect crops, resizes, re-compressions, and slightly edited copies of the same photo. Use for content moderation, copyright checks, and cleaning image datasets.
Output
Returns a perceptual hash distance score between the two input images, indicating how visually similar they are, along with a near-duplicate determination — whether the images are considered the same photo despite minor transformations like cropping, resizing, re-compression, or light editing.
Example use cases
Copyright infringement detection for UGC
“Someone uploaded this image to our platform — https://cdn.mysite.com/uploads/user123.jpg — can you check if it's a near-duplicate of our protected asset at https://assets.mysite.com/originals/protected-photo.jpg? I need to know if it's just a resized or re-compressed copy.”
Image dataset deduplication pipeline
“I'm cleaning a training dataset and I suspect these two images are duplicates: https://dataset.storage/img_0042.png and https://dataset.storage/img_0187.png. Can you compute their perceptual hash distance and tell me if I should remove one?”
Content moderation near-duplicate check
“A flagged image just came in — https://modqueue.example.com/flagged/abc.jpg — and I want to know if it matches a previously banned image at https://modqueue.example.com/banned/xyz.jpg, even if it's been slightly cropped or re-saved at lower quality.”
Technical details
Endpoint
POSThttps://api.kakerapetit.dev/v1/find-near-duplicateWhen to prefer
Choose this endpoint when you need to detect near-duplicates rather than exact byte-for-byte matches — it handles crops, resizes, re-compressions, and light edits that would fool a simple hash or checksum. Prefer it over exact-match comparisons for content moderation, copyright enforcement, and dataset deduplication. It is distinct from a general visual similarity scorer in that it specifically targets perceptual hashing for duplicate detection rather than semantic or stylistic similarity.
Side effects
- Image URL unreachable or returns non-200 — endpoint cannot fetch the image
- Image exceeds 10MB file size limit — request rejected
- Unsupported image format (not jpeg/png/webp/gif) — parsing error
- One or both URLs missing from request body — validation error
- Image URL serves non-image content — hash computation fails
- Network timeout fetching remote image — request may fail or time out
Input
