This repository contains implementation of my research based on the work during the 2021 Machine Larning for Visual Unerstanding course. You can see the final presentation and report which introduces our base model(seq2seq+attention).

To improve speed and achieve keypoit-free SLT, We constructed our model with three components.

• Lightweight Video encoder
  3d CNN(C3D, R(2+1)D, S3D)s to encode the video, returns the encoded features.
  
• Transformer Encoder
  Contextualizes the input features and returns glosses, which are word-level elements of the sign language.
  
• Sign Language Decoder
  The transformer decoder learn the relations between glosses and spoken language, and returns the translated text.
  The model is trained with RWTH-PHOENIX-Weather 2014 dataset which contains sign language videos from 5~30 seconds, and recorded a BLEU-4 score of 14.45.
