Imentiv’s Image Emotion API detects faces in still images and estimates facial expression emotions such as happiness, sadness, anger, fear, surprise, neutrality, disgust, and contempt. Product and research teams use it to score user photos, ad stills, UX tests, and gallery uploads without building a facial-coding pipeline from scratch.

How does image facial emotion analysis work?

The pipeline locates faces in an image, normalizes each face crop, and runs expression models that map visual cues to emotion scores. For group photos you get a per-face breakdown so you can compare individuals rather than a single blurry average.

Facial coding on still frames is complementary to video analysis: use images when you have screenshots, profile photos, print creative, or frame extracts; use the video API when temporal dynamics (rise and fall of affect) matter.

  • Face detection and recognition for single and multi-person images
  • Per-face emotion scores for detailed reporting
  • Straightforward HTTP integration suitable for batch or on-upload processing

What problems does an Image Emotion API solve?

Marketing teams score creative thumbnails and packaging stills before launch. Product teams measure facial response in moderated usability sessions. Safety and moderation workflows flag distress signals in user-generated content when policy allows facial analysis.

Because results are structured, you can filter by emotion threshold, aggregate across a campaign, or join scores to metadata like creative variant, locale, or device.

How should you design an image emotion workflow?

Collect images with consistent lighting and face size when possible; very small or occluded faces reduce confidence. Process asynchronously for large batches, store scores next to asset IDs, and surface both average and outlier faces in reports.

Pricing is credit-based per image. Start with a labeled sample set to calibrate thresholds for your use case before wiring production automations.
