On the Importance of Signer Overlap for Sign Language Detection

no code implementations19 Mar 2023 Abhilash Pal, Stephan Huber, Cyrine Chaabani, Alessandro Manzotti, Oscar Koller

We quantify this with a detailed analysis of the effect of signer overlap on current sign detection benchmark data sets.

Multi-channel Transformers for Multi-articulatory Sign Language Translation

no code implementations1 Sep 2020 Necati Cihan Camgoz, Oscar Koller, Simon Hadfield, Richard Bowden

Sign languages use multiple asynchronous information channels (articulators), not just the hands but also the face and body, which computational approaches often ignore.

MS-ASL: A Large-Scale Data Set and Benchmark for Understanding American Sign Language

no code implementations3 Dec 2018 Hamid Reza Vaezi Joze, Oscar Koller

Sign language recognition is a challenging and often underestimated problem comprising multi-modal articulators (handshape, orientation, movement, upper body and face) that integrate asynchronously on multiple streams.

Neural Sign Language Translation

1 code implementation CVPR 2018 Necati Cihan Camgoz, Simon Hadfield, Oscar Koller, Hermann Ney, Richard Bowden

SLR seeks to recognize a sequence of continuous signs but neglects the underlying rich grammatical and linguistic structures of sign language that differ from spoken language.

Re-Sign: Re-Aligned End-To-End Sequence Modelling With Deep Recurrent CNN-HMMs

no code implementations CVPR 2017 Oscar Koller, Sepehr Zargaran, Hermann Ney

This work presents an iterative re-alignment approach applicable to visual sequence labelling tasks such as gesture recognition, activity recognition and continuous sign language recognition.

Deep Hand: How to Train a CNN on 1 Million Hand Images When Your Data Is Continuous and Weakly Labelled

no code implementations CVPR 2016 Oscar Koller, Hermann Ney, Richard Bowden

Furthermore, we demonstrate its use in continuous sign language recognition on two publicly available large sign language data sets, where it outperforms the current state-of-the-art by a large margin.
