A Reverse Sign Language Dictionary: Open-Vocabulary Sign Recognition from Continuous Signing via Video Captioning and Description Retrieval
The clever bit is sidestepping the closed-set classification problem by treating it as retrieval over descriptions instead of gloss labels. This enables zero-shot recognition, which is genuinely useful. For accessibility work, this unblocks deployment without labeling every sign. Niche but well-motivated technical contribution.
