Simsiam Network Based Self-supervised Model for Sign Language Recognition.

To make a more accurate and robust deep learning model, more labeled data is required. Unfortunately, in many areas, it’s very difficult to manage properly labeled data. Sign language recognition is one of the challenging areas of computer vision, to make a successful deep learning model to recognize sign gestures in real-time, a huge amount of labeled data is needed. Authors have proposed a self-supervised learning approach to address this problem. The proposed architecture used Resnet50 v1 backbone-based simsiam encoder network to learn the similarity between two different images of the same class. Calculated cosine similarity passes to MLP head for further classification. The proposed study uses Indian and American Sign Language detests for simulation. The proposed methodology successfully achieve 74.59% of accuracy. Authors have also demonstrated the impact of other self-supervised deep learning models for sign language recognition.
