infrastructure-vision

Local computer-vision ops for OSINT/investigation: face detection (SCRFD) + face embedding (ArcFace, 512-d, L2-normalized), NMS, cosine similarity, and image preprocessing — built on infrastructure-onnx (ADR 0020). Default build is dependency-free (types + pure ops + stubs); the real ONNX models and image decode are behind feature `ort`.

What it is for

infrastructure-vision — local computer-vision ops for OSINT/investigation.

Face detection (SCRFD) + face embedding (ArcFace, 512-d, L2-normalized) on top of infrastructure_onnx, plus the pure ops (NMS, cosine similarity, letterbox + CHW preprocessing math). Local-only, no egress — the consumer owns privilege, biometric policy, and the vector store (ADR 0020).

The default build is dependency-free: the FaceDetector/FaceEmbedder traits, the pure ops, the value types, and StubFaceDetector/ StubFaceEmbedder all build with zero native deps. The real ONNX models + image decode live behind the ort feature (ScrfdDetector, ArcFaceEmbedder).

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

`crate root`

Re-exports. Exported here, defined elsewhere.

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

1 workspace crate depends on this one: application-vision.
