TSL-51: Thai Sign Language Videos and Landmarks for 52 Sign Classes

TSL-51 contains video recordings and landmark data for 51 specific Thai Sign Language signs and 76 target sentences. Created by Namonpas and updated in March 2026, the collection includes both isolated signs and continuous sentence structures. It provides both raw video and extracted pose-estimation landmarks for sign language recognition research.
