AWCV-100K

Mainstream real-world devices typically utilize standard RGB cameras and necessitate comprehensive coverage of commonly used words for effective communication. To tackle these challenges, we introduce AWCV-100K, a pioneering video-based air-writing dataset designed for real-world applications. AWCV-100K is a video-based air-writing Chinese character dataset, including 102,688 videos and comprising a total of 8.8 million video frames. The benchmark includes 3,755 Chinese characters from the GB1 set, encompassing 99.7% of characters used in daily communication, forming a comprehensive corpus. To ensure the developed model is robust to variations among different individuals, we have partitioned the dataset into three sets (i.e., training, validation, and testing) in an approximate ratio of 8:1:1, dividing the data by person.
