Overview
LipLens is a deep learning-based lip-reading application that converts silent video input into text by analyzing lip movements. Inspired by the LipNet architecture, the system uses computer vision and sequence modeling techniques to understand temporal patterns in speech without relying on audio.
The application provides an interactive interface using Streamlit and supports containerized deployment using Docker.
Key Features
Core Functionalities
- Video-to-Text Conversion: Predict spoken words from lip movements
- Frame Extraction Pipeline: Processes videos into sequential frames
- Deep Learning Model: Learns temporal patterns in lip motion
- Streamlit UI: Simple interface for uploading and testing videos
- Docker Support: Easy deployment and portability
- Pre-trained Model Support: Ready-to-use inference pipeline
How It Works
- Video Input → User uploads video
- Frame Extraction → FFmpeg / OpenCV processes frames
- Preprocessing → Focus on lip region
- Model Inference → Sequence passed through neural network
- Text Prediction → Output generated using learned patterns
Core Concept
The model learns from sequences of frames and predicts text using sequence modeling techniques.
This enables the system to map visual input (lip movements) to textual output.
Tech Highlights
- Computer Vision → Frame extraction & lip region processing
