# PrimateFace

Cross-species primate face analysis dataset with facial landmark annotations
for non-human primates. The dataset provides annotations in two landmark
conventions, enabling landmark conversion across schemes.

> **Note:** This dataset is actively growing. New species and configs are added
> over time. Check the configs table below for the latest available data.

## Landmark Conventions

PrimateFace supports two facial landmark configurations on the same images:

- **COCO 68-landmark** (): The standard dlib/COCO Whole-Body face
  keypoint layout (jaw contour, eyebrows, nose, eyes, mouth).
- **PrimateFace 49-landmark** (): A primate-optimized landmark set
  converted from 68-kpt via a trained attention-MLP model.

## Configs

Each config corresponds to a species group and annotation variant:

| Config | Species | Keypoints | Images | Annotations | Description |
|--------|---------|-----------|--------|-------------|-------------|
|  | Macaque | 68 (dlib/COCO) | 1,876 | 1,876 | Cayo Santiago action-unit videos |
|  | Macaque | 48 (PrimateFace) | 1,876 | 1,876 | Cayo Santiago action-unit videos |
|  | Marmoset | 68 (dlib/COCO) | 3,663 | 4,315 | Bing images across 5 genera (Callithrix, Cebuella, Mico, Callimico, Callibella) |
|  | Marmoset | 49 (PrimateFace) | 3,663 | 4,315 | Same images, converted to 49-kpt via attention-MLP |
