• Abstract: Sign language is a visual language used by the deaf and dumb community to communicate. However, for most recognition methods based on monocular cameras, the recognition accuracy is low and the robustness is poor. Even if the effect is good on some data, it may perform poorly in other data with different interference due to the inability to extract effective features. To solve these problems, we propose a sign language recognition network that integrates skeleton features of hands and facial expression. Among this, we propose a hand skeleton feature extraction based on coordinate transformation to describe the shape of the hand more accurately. Moreover, by incorporating facial expression information, the accuracy and robustness of sign language recognition are finally improved, which was verified on A Dataset for Argentinian Sign Language and SEU's Chinese Sign Language Recognition Database (SEUCSLRD).

  This work proposes an Isolated Sign Language Recognition (ISLR) approach where body, hands, and facial landmarks are extracted throughout time and encoded as 2-D images. We show that our method surpassed the state-of-the-art in terms of performance metrics on two widely recognized datasets in Brazilian Sign Language (LIBRAS) In addition to being more accurate, our method is more time-efficient and easier to train due to its reliance on a simpler network architecture and solely RGB data as input.

  We argue that the current benchmark data sets for sign language detection estimate overly positive results that do not generalize well. We quantify this with a detailed analysis of the effect of signer overlap on current sign detection benchmark data sets. We propose new data set partitions that are free of overlap and allow for more realistic performance assessment.
