GestureLingo
A Sign Language Recognition System for Speech-Impaired People
Aim
The aim behind this work is to develop a system for recognizing the sign language, which provides communication between people with speech impairment and normal people, thereby reducing the communication gap between them.
Objective
The main objective is to translate sign language to text/speech. It provides a helping-hand for speech-impaired to communicate with the rest of the world using sign language. This leads to the elimination of the middle person who generally acts as a medium of translation. This would contain a user-friendly environment for the user by providing speech/text output for a sign gesture input.
Problem definition
The only mode of interaction for deaf-mute people is sign language. The problem is not confined only to a deaf-mute person who is unable to hear or speak, but another problem is lack of awareness of deaf culture by normal people. Majority of hearing people have either no/little knowledge or experience of sign language . There are also more than 300 sign languages and it is hard for a normal person to understand and become used to these languages. Hence it creates a communication barrier between the disabled and society.
Technology being used
- Python 3.7
- TensorFlow
- Keras
- OpenCV
- MySQL
- Text-to-Speech API
Algorithms used
- Rule Based Classifier
- Background subtraction method by detecting the color of skin using HSV (Hue Saturation Value) model.
Implementation
- This system would involve 4 steps:
- Hand detection
- Fingers and Palm Segmentation.
- Finger Recognition
- Hand Gesture Recognition
-
Label the gestures using OpenCV Captures images of hands using VideoCapture and frame function which uses web cam feed.
-
Adding variations Captures images at different angles and rotations and flipping the images matches them with labels.
-
Store in database Consists of captured gestures based on American Sign Language.
-
Train the model - using Keras
-
Testing - Testing of the model with real-time gesture use.
