Hand gestures play a dominant role in the expression of sign language. Current deep-learning based video language recognition (SLR) methods usually follow data-driven paradigm under supervision category label. However, those suffer limited interpretability and may encounter overfitting issue due to data sources. In this paper, we introduce hand prior propose new hand-model-aware framework for i...

Preface For as long as I can remember, I have been interested in languages. Sign languages especially fascinate me, because they are natural languages using a different modality: sign languages use images as the vehicle for information. This has strange implications: in sign language, it is easy to have a conversation with someone at the other side of a crowded room. On the other hand, it is im...

Given the current lack of appropriate assessment tools for measuring deaf children's sign language skills, many test developers have used existing tests of other sign languages as templates to measure the sign language used by deaf people in their country. This article discusses factors that may influence the adaptation of assessment tests from one natural sign language to another. Two tests wh...

Sign language processing is often performed by processing each individual sign and most of existing sign language learning systems focus on lexical level. Such approaches rely on an exhaustive description of the signs and do not take in account the spatial structure of the sentence. We present a high level model of sign language that uses the construction of the signing space as a representatio...

Sign Language is a means of communication between audibly challenged people. To provide an interface between the audibly challenged community and the rest of the world we need Sign Language translators. A sign language recognition system computerizes the work of a sign language translator. Every Sign Language Recognition (SLR) System is trained to recognize specific sets of signs and they corre...

Sign language is the basic means of communication among hearing-impaired people. Systems that could act as interpreters between vocal and hearing-impaired people would facilitate the life of deaf and integrate them in the society. Such systems should perform bidirectional translation of sign language and spoken language. A lot of efforts invested on translating sign languages to spoken language...
