We develop a real-time, robust and accurate sign language recognition system leveraging deep convolutional neural networks(DCNN). Our framework is able to prevent common problems such as error accumulation of existing frameworks and it outperforms state-of-the-art frameworks in terms of accuracy, recognition time and usability.
We propose a novel spatial-temporal feature set for sign language recognition, wherein we construct explicit spatial and temporal features that capture both hand movement and hand shape. Experimental results show that the proposed solution outperforms existing one in terms of accuracy.
