Dataset of Common phrases in Indian Sign Language

Sign Language Recognition is a breakthrough for helping deaf-mute people and has been researched for many years. It is still a challenge for deaf and dumb people to normally have a conversation since most people aren’t acquainted with sign language. But owing to recent technology, we are better able to understand people using sign language. This dataset contains images of the most common phrases in Indian Sign Language. The images of ISL are captured using a standard webcam of a laptop with a resolution of 1280*720. These include 30 images of 40 different signs from ISL. Images are not filtered or resized, are captured under varying light intensities and different backgrounds, and stored in NumPy arrays. These images are of static sign language phrases and do not include any dynamic sign.手语识别（Sign Language Recognition）是一项助力听障人群的突破性技术，相关研究已开展多年。由于多数人并不熟悉手语，听障人群难以实现日常顺畅交流，这一领域至今仍面临诸多挑战。而近年来的技术进步，使得我们能够更精准地识别手语使用者的表达。本数据集包含印度手语（Indian Sign Language，ISL）中最常用的日常语句图像，这些图像通过笔记本电脑的标准网络摄像头采集，分辨率为1280×720。数据集涵盖印度手语中40种不同手势的各30张样本图像，所有图像均未经过滤波处理或尺寸调整，采集场景涵盖不同光照强度与多样背景，并以NumPy数组格式存储。本数据集包含的均为静态手语语句图像，不涉及任何动态手势。
