Biomechanics Diagnostic & Science Communication
- Vector Coordinate Mapping: Converts pixel 2D landmarks into calibrated spatial vectors for localized angular dynamic calculation.
- Angular Velocity Derivation: Evaluated via central difference formula:
ω = (θ[t+Δt] - θ[t-Δt]) / (2·Δt)filtered with exponentially weighted moving average. - Center of Mass (CoM): Estimated using segmental mass fractions (Winter biomechanics model) across key torso, hip, and limb vertices.
- Forensic Motion Note: Optical noise is distinguished from micro-gesture motion cadence through dynamic confidence thresholding.
