One-Stage-TFS: Thai One-Stage Fingerspelling Dataset

The Thai One-Stage Fingerspelling (One-Stage-TFS) dataset is a comprehensive resource designed to advance research in hand gesture recognition, explicitly focusing on the recognition of Thai sign language. This dataset comprises 7,200 images capturing 15 one-stage consonant gestures performed by undergraduate students from Rajabhat Maha Sarakham University, Thailand. The contributors include both expert students from the Special Education Department with proficiency in Thai sign language and students from other departments without prior sign language experience. Images were collected between July and December 2021 using a DSLR camera, with contributors demonstrating hand gestures against both simple and complex backgrounds. The One-Stage-TFS dataset presents challenges in detecting and recognizing hand gestures, offering opportunities to develop novel end-to-end recognition frameworks. Researchers can utilize this dataset to explore deep learning methods for hand detection, followed by feature extraction and recognition using techniques like convolutional neural networks, transformers, and adaptive feature fusion networks. The dataset supports a wide range of applications in computer science, including deep learning, computer vision, and pattern recognition, thereby encouraging further innovation and exploration in these fields.
