# Video-Summary
# Video Summary and Classification
[![CI](https://github.com/Askill/Video-Summary/workflows/CI/badge.svg)](https://github.com/Askill/Video-Summary/actions)
[![Python 3.8+](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
## Example:
A Python-based video summarization tool that extracts contours from video frames to create condensed summaries. Perfect for analyzing surveillance footage, time-lapse videos, or any static camera recording where you want to extract and visualize movement over time.
usage:
main.py input_video.mp4 output_dir ?config_file.json
![docs/demo.gif](./docs/demo.gif)
What you see above is a 15 second excerpt of a 2 minute overlayed synopsis of a 2.5h video from an on campus web cam.
The synopsis took 40 minutes from start to finish on a 8 core machine and used a maximum of 6Gb of RAM.
## ✨ Features
However since the contour extraction could be performed on a video stream, the benchmark results show that a single core would be enough to process a video faster than real time.
- **Movement Detection**: Automatically detects and extracts moving objects from static camera footage
- **Layer-Based Processing**: Groups related movements across frames into coherent layers
- **Heatmap Generation**: Visualizes areas of activity in the video
- **Configurable**: Extensive configuration options for fine-tuning detection sensitivity
- **Efficient**: Processes video faster than real-time on modern hardware
- **Caching**: Saves intermediate results for faster re-processing with different parameters
## Heatmap
![](./docs/heatmap_x23.png)
## 🚀 Quick Start
### Installation
## Benchmark
Below you can find the benchmark results for a 10 minutes clip, with the stacked time per component on the x-axis.
The tests were done on a machine with a Ryzen 3700X with 8 cores 16 threads and 32 Gb of RAM.
On my configuration 1 minutes of of the original Video can be processed in about 20 seconds, the expected processing time is about 1/3 of the orignial video length.
```bash
# Clone the repository
git clone https://github.com/Askill/Video-Summary.git
cd Video-Summary
- CE = Contour Extractor
- LE = LayerFactory
- LM = LayerManager
- EX = Exporter
# Create virtual environment
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
![docs/demo.gif](./docs/bm.jpg)
# Install dependencies
pip install -r requirements.txt
### Configuration
# Install system dependencies (Linux)
sudo apt-get install ffmpeg libsm6 libxext6 libxrender-dev
```
./Application/Config.py
### Basic Usage
"min_area": 100, min area in pixels, of a single contour, smaller is ignored
"max_area": 9000000, max area in pixels, of a single contour, larger is ignored
"threshold": 6, luminance difference threshold, sensitivity of movement detection
"resizeWidth": 600, video is scaled down internally
"inputPath": None, overwritten in main.py
"outputPath": None, overwritten in main.py
"maxLayerLength": 5000, max length of Layer in frames
"minLayerLength": 10, min length of Layer in frames
"tolerance": 100, max distance (in pixels) between contours to be aggragated into layer
"maxLength": None,
"ttolerance": 60, number of frames movement can be apart until a new layer is created
"videoBufferLength": 100, Buffer Length of Video Reader Componenent
"LayersPerContour": 2, number of layers a single contour can belong to
"avgNum": 10, number of images that should be averaged before calculating the difference
(computationally expensive, needed in outdoor scenarios due to clouds, leaves moving in the wind ...)
```bash
# Process a video with default settings
python main.py input_video.mp4 output_dir
### notes:
optional:
# Use custom configuration
python main.py input_video.mp4 output_dir config.json
install tensorflow==1.15.0 and tensorflow-gpu==1.15.0, cuda 10.2 and 10.0, copy missing files from 10.0 to 10.2, restart computer, set maximum vram
# Enable verbose logging
python main.py input_video.mp4 output_dir --verbose
```
## 📊 Example Output
![Demo GIF](./docs/demo.gif)
*A 15-second excerpt of a 2-minute overlaid synopsis of a 2.5-hour video from a campus webcam.*
### Heatmap Visualization
![Heatmap](./docs/heatmap_x23.png)
The heatmap shows areas of activity throughout the video, with brighter regions indicating more movement.
## ⚙️ Configuration
Create a JSON configuration file to customize processing parameters:
```json

"tolerance": 20,
"ttolerance": 50,
"videoBufferLength": 250,
"LayersPerContour": 220,
"avgNum": 10
}
```

| `videoBufferLength` | Buffer length of Video Reader component | 250 |
| `LayersPerContour` | Number of layers a single contour can belong to | 220 |
| `avgNum` | Number of images to average before calculating difference | 10 |
> **Note**: `avgNum` is computationally expensive but needed in outdoor scenarios with clouds, leaves moving in wind, etc.

### Processing Pipeline
1. **Video Reading**: Load and preprocess video frames
2. **Contour Extraction**: Detect movement by comparing consecutive frames
3. **Layer Creation**: Group related contours across frames
4. **Layer Management**: Filter and optimize layers based on configuration
5. **Export**: Generate output video with overlaid movement and heatmap
## 🧪 Development
### Code Quality Tools
We use modern Python development tools:
- **Black**: Code formatting
- **isort**: Import sorting
- **flake8**: Linting
- **mypy**: Type checking
- **pre-commit**: Automated checks
```bash
# Install development dependencies
pip install -e ".[dev]"
# Install pre-commit hooks
pre-commit install
# Run formatting
