## Overview
|
|
This project is used to analyze videos from security cameras and shows short clips from the videos which contain detected motions.
|
|
It uses C# programming language, .NET Framework 4.6 and [Accord.NET](http://accord-framework.net) libraries
|
|
|
|
## Algorithm overview
|
|
1. The algorithm reads first frames of every half-second (e.g. if a video has framerate of 30 the algorithm retrieves 1st frame, 15th, 30th, 45th and so on)
|
|
2. Images are converted to Grayscale
|
|
3. Images' pixels are compared to each other
|
|
4. Highlights regions with an area of changed pixels 35x35 or more
|
|
5. Creates video segments metadata based on "moving" frames
|
|
6. Segments with the distance between is less than 5 seconds are combined
|
|
7. Segments with the duration less than 3 seconds are deleted
|
|
8. Segments data is recorded to ".data" file with JSON structure
|

## Dependencies
|
|
- **K-Lite Codec Pack** - used for video playback. The program will crash without this codec. Other codecs might do well but I've not checked.
|
|
- **DirectX Playback library** - used for playback as well as codec
|
|
|
|
## Getting Started
|
|
1. Install [K-Lite Codec Pack](https://www.codecguide.com/download_kl.htm) (Any edition will do)
|
|
2. Launch Visual Studio 2017 or later
|
|
3. Go to "View -> Team explorer"
|
|
4. In the Team explorer click "Manage connections button" and click "Clone" button
|
|
5. Insert Git URL from repository GitHub page and clone repository to your PC
|
|
6. Open MotionDecoder solution
|
|
7. Go to "Solution Explorer -> MotionDecoder -> References" and check if all dependencies are loaded
|
|
8. If DirectX libraries are missing add them through "References -> (double-click) -> Add Reference -> Browse" (Libraries are situated in "{Repository root}/Dependencies")
|
|
6. Build and debug solution
