description: BASKETech: Basketball Technique Correction with Action Recognition and Temporal Feature Extraction

Overview

BASKETech is an intelligent system for basketball technique correction that integrates action recognition, temporal feature extraction, and an action comparison mechanism.This framework leverages advanced multimodal deep learning, combining spatial and temporal modeling, to provide real-time, personalized feedback on player technique.

The core architecture includes:



DTFEM (Dynamic Temporal Feature Extraction Model)

Multimodal Encoder Architecture

Adaptive Feedback Mechanism


Together, these modules enable high-precision recognition, real-time correction, and automated training insights, making BASKETech suitable for professional athletes, amateur players, and sports analytics research.



✨ Features

Dynamic Temporal Feature Extraction



Captures spatial features via convolutional layers and temporal dynamics using recurrent networks.

Integrates reduced self-attention, Mamba blocks, and context broadcasting networks.

Enables fine-grained recognition of dribbling, shooting, passing, and complex basketball movements.(See Fig. 1, p.7 for DTFEM architecture.)


Multimodal Encoder Architecture



Combines CNN and LSTM modules to model both frame-level details and long-term dependencies.(See Fig. 2, p.8 for encoder design.)

Supports dynamic local adapters for vision-language fusion, improving contextual understanding.


Action Comparison Mechanism



Aligns extracted player features with ideal reference techniques using similarity measures.

Computes similarity scores with Euclidean or cosine distance to highlight deviations.

Triggers adaptive corrective feedback for real-time improvement.


Adaptive Feedback Mechanism



Provides immediate and personalized training suggestions.

Enables player-specific performance monitoring and technique optimization over time.
