Models are included in /model-* folders
Models descriptors have been additionally modified for readability
Supports:
MoveNet-Lightningv3 and v4MoveNet-Thunderv3 and v4MoveNet-Multiposev1
Performance:
- Lightning v3: 5.450ms
- Lightning v4: 5.481ms
- Thunder v3: 10.388ms
- Thunder v4: 10.508ms
- Multipose: 11.217ms
Actual model parsing implementation in movenet.js and movenet-multipose.js does not follow original
and is implemented using native TFJS ops and optimized for JavaScript execution
Function processResults() takes model.execute output and returns array of 17 keypoints:
- id
- score: score as number
- label: annotated body part as string
- xRaw: x coordinate normalized to 0..1
- yRaw: y coordinate normalized to 0..1
- x: x coordinate normalized to input image size
- y: y coordinate normalized to input image size
