Core Capabilities Traditional image redaction relies on face-only detectors or manual masking. HaS Image is an **on-device privacy segmentation model** — it recognizes 21 categories of sensitive content with pixel-level masks, enabling precise and automated redaction. | Capability | Description | |------------|-------------| | **21 Privacy Categories** | Covers biometrics (face, fingerprint, palmprint), ID documents (ID card, passport, permit), financial (bank card), screens (mobile, monitor), and more | | **Pixel-Level Segmentation** | Instance segmentation, not just bounding boxes — masks follow the exact contour of each sensitive region | | **Multiple Redaction Methods** | Supports mosaic, Gaussian blur, and solid fill — configurable strength and style per use case | | **Batch Processing** | Process entire directories of images in one command | | **Category Filtering** | Selectively redact only specific categories (e.g., faces only, or faces + license plates) | | **High Speed** | ~20ms per image, suitable for real-time and batch workflows | ## 2. Supported Privacy Categories 6 groups, 21 categories: | Group | ID | Category | Description | |-------|----|----------|-------------| | **Biometrics** | 0 | `face` | Human faces | | | 1 | `fingerprint` | Fingerprints | | | 2 | `palmprint` | Palm prints | | **ID Documents** | 3 | `id_card` | National ID cards | | | 4 | `hk_macau_permit` | HK/Macau travel permits | | | 5 | `passport` | Passports | | | 6 | `employee_badge` | Employee badges | | **Transportation** | 7 | `license_plate` | Vehicle license plates | | **Financial** | 8 | `bank_card` | Bank/credit cards | | **Security** | 9 | `physical_key` | Physical keys | | **Documents** | 10 | `re...
