Overview
This IP relates to advanced image processing, specifically the analysis of sequences of video frames showing the movement of a subject and comparing that movement to a reference motion. The patented technology is applicable across digital fitness, sports analytics, physical therapy, remote coaching, motion capture, AI-driven form correction, and computer-vision systems.
Key Advantages of the Technology
• Processes video frames of a user performing an exercise and compares the movement to expert reference motion captured from reference video frames.
• Extracts pixel information and generates dedicated motion data frames, supporting high-resolution instructional feedback with configurable area segments.
• Computes a similarity metric to quantify how closely the user's movement matches the reference, enabling automated form evaluation and precise corrective feedback.
• Defines a motion data frame that incorporates a face vector representing positional changes across frames, improving accuracy in tracking movement.
• Integrates reference frame rate data and area-segment configuration rules to ensure proper subject positioning and scale before analysis.
• Includes a motion data frame generation unit that dynamically defines area segments relative to face position and size.
• Incorporates a user-feedback unit that determines whether the user is correctly positioned and delivers visual and/or audio feedback based on system evaluation.
• Detects user position and size in real time and processes area segments independently of face vectors, improving system consistency and accuracy.
