toposync-ext-vision 0.1.7

Toposync first-party extension: task-oriented vision operators.

Toposync Vision extension

First-party extension focused on public task-oriented vision operators for the Pipelines runtime.

What it provides

• vision.detect
• vision.track
• vision.segment_instances
• vision.pose_estimate (skeleton only; not launched yet)

The public surface is task-based, not vendor-based. The official first-party runtime is ONNX Runtime, with CPU as the default execution path.

Dependencies

• The default toposync application bundle includes the first-party ONNX Runtime CPU stack.
• The GPU-oriented first-party bundles are published separately:
  • toposync-vision-cuda
  • toposync-vision-directml
• The official extension package now also includes the first-party tracker stack:
  • simple_iou_kalman
  • norfair

Notes

• vision.detect resolves ModelManifest entries and builds an ONNX Runtime backend automatically when runtime=onnxruntime.
• By default, the ONNX Runtime backend prefers CPUExecutionProvider. Optional acceleration is opt-in via the toposync-vision-cuda / toposync-vision-directml bundles or TOPOSYNC_VISION_ONNXRUNTIME_PROVIDERS.
• Manifest files can be loaded from TOPOSYNC_VISION_MANIFESTS_DIR or TOPOSYNC_VISION_MANIFEST_PATHS.
• Custom manifests imported from the UI are persisted under .toposync-data/vision-manifests/ for the selected processing server.
• Built-in first-party manifests ship inside the wheel, but their ONNX weights do not. When no checkout-local artifact exists, official model ids resolve to TOPOSYNC_DATA_DIR/vision-models/... (or .toposync-data/vision-models/... by default).
• The extension now ships a built-in RTMDet detection shortlist in extensions/vision/manifests/:
  • rtmdet_det_tiny
  • rtmdet_det_small
  • rtmdet_det_medium
• The extension now also ships a built-in RF-DETR detection shortlist in extensions/vision/manifests/:
  • rfdetr_det_nano
  • rfdetr_det_small
  • rfdetr_det_medium
• In a source checkout, existing local artifacts under extensions/vision/models/... are still honored.
• In installed environments, official artifacts belong under the managed model store in TOPOSYNC_DATA_DIR/vision-models/... and are intentionally not bundled in the published package.
• The validated manual provisioning flow is documented in docs/VISION_MODEL_PROVISIONING.md.
• The initial assisted-provisioning foundation for RTMDet detection is already exposed in catalog metadata:
  • upstream checkpoint/config/metafile/paper links
  • planned local builder backend
  • planned supported platforms
  • explicit-consent requirement
• The UI can also trigger installation for models that have an admin-configured source. Supported source env vars are:
  • TOPOSYNC_VISION_MODEL_SOURCE_<MODEL_ID>
  • TOPOSYNC_VISION_MODEL_URL_<MODEL_ID>
  • TOPOSYNC_VISION_MODEL_PATH_<MODEL_ID>
  • TOPOSYNC_VISION_OFFICIAL_MODEL_SOURCE_DIR
  • TOPOSYNC_VISION_OFFICIAL_MODEL_BASE_URL
• RTMDet detection now also has an experimental assisted local build path:
  • Linux only in this phase
  • requires a local container runtime (docker or podman) on the processing server
  • still downloads the upstream checkpoint directly on that machine
  • still validates the exported end2end.onnx against the manifest checksum
  • now records provenance per job, including actor, accepted upstream sources, builder metadata, and final ONNX sha256
  • still keeps manual upload as the stable fallback path
  • can be started from the model recovery card or the Processing Servers screen
• RF-DETR detection now also has an experimental assisted local build path:
  • supports linux, darwin, and windows hosts in this phase
  • uses a host Python builder (rfdetr[onnx]) instead of MMDeploy
  • downloads the upstream checkpoint directly on that machine before exporting the ONNX locally
  • keeps manual ONNX upload available as the stable fallback path
  • is prioritized in the operator UI when nothing is installed and the local builder is actually available on that machine
• Remote download sources are only enabled when the manifest explicitly allows redistribution. The current built-in RTMDet/RTMDet-Ins manifests do not, so the safe first-party flow is local admin-managed copy.
• Product policy: RTMDet and RTMDet-Ins stay on guided_upload for now. RF-DETR is available only through assisted local build in this phase; it is not mirrored, bundled, or redistributed by TopoSync.
• Product policy: Ultralytics/YOLO is not part of the official first-party vision runtime path.
• The extension now also ships a built-in RTMDet-Ins segmentation shortlist:
  • rtmdet_ins_tiny
  • rtmdet_ins_small
  • rtmdet_ins_medium
• RTMDet manifests use the dedicated mmdet_rtmdet parser, letterbox preprocessing, and COCO-80 labels.
• RF-DETR manifests use the dedicated rfdetr_detr parser and the official DETR-style dets + labels ONNX outputs.
• RTMDet-Ins manifests use the dedicated mmdet_rtmdet_ins parser and produce real binary mask artifacts.
• The processing server status now exposes:
  • heuristic hardware recommendations
  • runtime upgrade suggestions for CUDA / DirectML bundles
  • a per-task model catalog with availability (available, manifest_only, incompatible)
  • installation capability and progress for models that can be fetched/copied automatically
  • badges such as recommended, fastest, best_quality, edge
• vision.detect can either filter the stream to packets that contain detections (emit_mode="events") or keep every frame annotated (emit_mode="annotate").
• vision.track is now first-party and detector-agnostic: it consumes payload["vision"]["detections"].
• Every TrackedObject now carries camera_id, and can optionally carry world_anchor plus appearance_embedding_artifact_name for future multi-camera association work.
• vision.segment_instances writes payload["vision"]["segmentations"], attaches mask artifacts when enabled, and exposes the top mask as the semantic image key mask.
• vision.pose_estimate already reserves the public operator id, config schema, packet contract, and task=pose registry path so future pose models can land without breaking the architecture.
• Tracking contracts already carry optional keypoints, so future pose-aware trackers do not require a structural rewrite.
• ModelManifest now also accepts optional capabilities such as reid, so future re-identification models can be cataloged without changing the registry shape.
• The pipeline editor now chooses models by task, not framework/vendor id. Basic setup is guided for common users, while advanced details expose runtime/model internals and custom manifest import when needed.
• The first-party tracking backends are:
  • simple_iou_kalman
  • norfair
• vision.track supports:
  • emit_mode="events" for split-stream lifecycle packets per object
  • emit_mode="annotate" for frame passthrough with payload["vision"]["tracks"]
• vision.detect keeps per-object lifecycle semantics out of scope; use vision.track when you need temporal identity instead of simple frame filtering.
• Crop by bbox remains in com.toposync.cameras as camera.object_crop; it is not instance segmentation.
