Convert landmark list to Halpe 26-keypoint full body schema

Use This When

• Standardizing pose landmarks to Halpe-26 format with foot detail keypoints
• Building pose analysis requiring ankle, heel, and toe landmarks for gait analysis
• Interfacing with components expecting Halpe schema including head, neck, hip keypoints
• Preparing full-body pose data for sports analytics or biomechanics applications

What It Does

• Converts ordered 26-point landmark list to structured Human26 format with named fields
• Maps full body including head, neck, hip, and detailed foot keypoints (toes, heels)
• Validates minimum landmark count and fails if fewer than 26 landmarks provided
• Returns typed Landmarks2d.Human26 structure for downstream full-body analysis

Works Best With

• Halpe pose detector → this component → gait analysis or sports biomechanics
• Full-body pose estimation → this component → pose-based action recognition
• Integration with visualize for complete skeleton rendering including feet
• Feeding analytics requiring precise foot placement or balance analysis

Caveats

• Requires exactly 26 or more landmarks; fails with fewer even if partial pose sufficient
• No validation that landmark semantics match Halpe ordering; assumes correct input sequence
• Foot keypoints require high resolution and clear view; occlusion reduces quality
• Additional landmarks beyond 26 ignored; uses only first 26 points in order
