Compact Grinder — On-Screen Process Guide

The on-screen text covers direction, light, start and speed controls; an order for valve-stem and housing-bore work; holder selection; forward/back grinding movement; a tapered rod; and diameter, flexibility, stroke and flow checks. There is no expert narration, so terminology and intent require practitioner confirmation.

First you need to grind the valve stem. Second, while grinding the valve stem, you need to grind the middle hole of the housing.

Executed visual models and admission decisions

The interface reports run status, artifacts and limits—not just model names. Capabilities that did not run are not presented as demo outputs.

SAM 3.1segmentation

Runtime unavailable

CUDA runtime and an approved SAM 3.1 checkpoint are required; neither is available in this local build environment.

TAPNext++point tracking

Runtime unavailable

The official tracker environment/checkpoint has not been installed, and this runtime has no CUDA accelerator.

CoTracker3point tracking

Runtime unavailable

The official tracker environment/checkpoint has not been installed, and this runtime has no CUDA accelerator.

DINOv3correspondence

Runtime unavailable

DINOv3 is conditional on a demonstrated re-identification failure; its approved weights/runtime are not present locally.

MediaPipe Hand Landmarkerhand pose · Baseline

Completed

Landmarks are analysis previews until a human accepts coverage and identity for each clip; coverage alone cannot validate instructional meaning.

RTMPose Handhand pose · Selected 2D challenger

Runtime unavailable

A local pose-only screening found one strong result among four manually bounded bare-hand crops and no strong result among four glove crops; one glove skeleton was visibly misleading. Keep this challenger unavailable for publication until detector, full-clip temporal, source-hash and license gates pass.

HaMeR 3D hand meshhand mesh · Selected 3D challenger

Runtime unavailable

Selected 3D-mesh challenger for grip geometry and partial occlusion. It requires an external CUDA run plus approved HaMeR checkpoint and MANO-model terms; no mesh output has been produced in this build.

Dyn-HaMRhand mesh · Research comparator only

Not admitted

Technically relevant for temporally consistent 4D interacting-hand motion, but the official code and models are restricted to non-commercial research and also depend on MANO. It is not admitted as a Denso demo dependency.

YOLOdetection

Not admitted

No repeated domain-labelled detection task has been defined; generic boxes would add visual noise without instructional evidence.

SAM 2.1 Hiera Tinysegmentation

Completed

Reviewer- or VLM-proposed keyframes only; masks are not yet propagated through the full clip and remain review-pending.

SAM 2.1 Hiera Tiny video predictorsegmentation

Completed

Reviewer- or VLM-proposed bounded clips only. Start/middle/end identity and drift checks remain review-pending; masks are suppressed outside generated windows.
