Keypoint-Based Isolated Sign Language Recognition via Multi-Stream MLP and Temporal Attention BiLSTM

In this paper, we propose a keypoint-based isolated sign language recognition (ISLR) system addressing four challenges in large-vocabulary recognition: signer-dependent spatial variance, temporal dynamics, class imbalance, and multi-stream feature fusion. Using MediaPipe Holistic, we extract 1,662-dimensional skeletal...
