# 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

# Install dependencies
pip install -r requirements.txt
### Configuration
# Install system dependencies (Linux)
sudo apt-get install ffmpeg libsm6 libxext6 libxrender-dev
```
./Application/Config.py
### Docker Installation (Recommended)

For a consistent environment without system dependency issues:
### notes:
optional:
```bash
# Build the Docker image
docker build -t video-summary .
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
# Run with Docker
docker run -v $(pwd)/input:/app/input -v $(pwd)/output:/app/output video-summary /app/input/video.mp4 /app/output
# Or use Docker Compose
docker-compose run --rm video-summary /app/input/video.mp4 /app/output
```
### Basic Usage
```bash
# Process a video with default settings
python main.py input_video.mp4 output_dir

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
Video-Summary supports both JSON and YAML configuration files. YAML is recommended for its readability and support for comments.
### Example YAML Configuration
```yaml
# Detection sensitivity
min_area: 300 # Minimum contour area in pixels
max_area: 900000 # Maximum contour area in pixels
threshold: 7 # Movement detection sensitivity (lower = more sensitive)
# Processing parameters
resizeWidth: 700 # Processing width (smaller = faster but less accurate)
videoBufferLength: 250 # Frame buffer size
# Layer management
maxLayerLength: 5000 # Maximum frames per layer
minLayerLength: 40 # Minimum frames per layer
tolerance: 20 # Pixel distance for grouping contours
ttolerance: 50 # Frame gap tolerance
# Advanced
LayersPerContour: 220 # Max layers per contour
avgNum: 10 # Frame averaging (higher = less noise, slower)
```
### Pre-configured Profiles
Use the provided configuration profiles in the `configs/` directory:
```bash
# Default balanced settings
python main.py video.mp4 output configs/default.yaml
# High sensitivity - detect smaller movements
python main.py video.mp4 output configs/high-sensitivity.yaml
# Low sensitivity - outdoor scenes, reduce noise
python main.py video.mp4 output configs/low-sensitivity.yaml
# Fast processing - optimized for speed
python main.py video.mp4 output configs/fast.yaml
```
### Environment Variable Overrides
Override any configuration parameter using environment variables:

cp configs/default.yaml configs/my-custom.yaml
# Edit my-custom.yaml with your preferred settings
python main.py input_video.mp4 output_dir configs/my-custom.yaml
```
## Parameter Tuning Guide
### Increasing Sensitivity (detect more movement)
- Decrease `threshold` (e.g., 4-5)
- Decrease `min_area` (e.g., 100-200)
- Decrease `minLayerLength` (e.g., 20-30)
### Decreasing Sensitivity (reduce noise)
- Increase `threshold` (e.g., 10-15)
- Increase `min_area` (e.g., 500-1000)
- Increase `minLayerLength` (e.g., 60-100)
- Increase `avgNum` (e.g., 15-20)
### Improving Performance
- Decrease `resizeWidth` (e.g., 480-600)
- Decrease `videoBufferLength` (e.g., 100-150)
- Decrease `avgNum` (e.g., 5)
### Handling Outdoor Scenes
- Increase `avgNum` (e.g., 15-20) to smooth out clouds/leaves
- Increase `threshold` (e.g., 10-12)
- Increase `ttolerance` (e.g., 80-100) for wind-affected objects
