Spatial-Temporal Feature Extraction for Tanzanian Sign Language Recognition in Medical Diagnostics
摘要
The communication gap between doctors and patients with hearing impairment creates significant obstacles in delivering medical diagnoses to patients from Tanzania. In this paper, we introduce a paradigm of assessing Tanzania Sign Language identification by using spatial-temporal feature extraction to bridge this gap. We build a model combining Support Vector Machines (SVM) for classification, Long Short Term Memory (LSTM) networks for temporal modeling, and Convolutional Neural Networks (CNN) for spatial feature extraction. Our model reached 95% accuracy, 96% precision, 94% recall, and a 95% F1 score by analyzing 2,314 video samples of 32 common medical terms. These results surpass previous state-of-the-art methods, including independent SVM or CNN models, which generally achieve 85–90% accuracy in tasks for recognizing sign language. Our methodology surpasses prior benchmarks by 5% in recognition accuracy because it connects spatial and temporal modeling approaches to develop a comprehensive tool for enhancing healthcare services to deaf and hard-of-hearing Tanzanians.
