[0002] Deep learning models, especially convolutional neural networks and recurrent neural networks, are widely used in sign language recognition. Convolutional neural networks are good at processing image data and can extract the spatial features of sign language gestures, such as gesture shape and hand position, while recurrent neural networks are good at processing time series data and can capture the dynamic features of sign language gestures, such as gesture migration and speed. Sign language recognition devices are based on this and use cameras to extract gesture images and translate them to ensure normal communication between hearing-impaired people and the outside world.
