Geo-ConvGRU: Geographically Masked Convolutional Gated Recurrent Unit for Bird-Eye View Segmentation

Guanglei Yang, Yongqiang Zhang, Wanlong Li, Yu Tang et autres

Convolutional Neural Networks (CNNs) have significantly impacted various computer vision tasks, however, they inherently struggle to model long-range dependencies explicitly due to the localized nature of convolution operations. Although Transformers have addressed limitations in long-range dependencies for the spatial dimension, the temporal …

AI-Enabled Sign Language Recognition and Communication System for Speech/Hearing-Impaired Users

Feng Wen

The recognition of sign language is of great significance to remove the communication barrier between the speech/hearing impaired and the public. Current intuitive glove solutions are limited to recognize discrete simple gestures (i.e., numbers, letters, or words), far from satisfying the need …
