Key Frame Extraction using Differential Evolution

Python scripts that implement DE for extraction of key frames from a video stream.

NOTE: This repository is intended as a backup for my final year project files.

Requirements:

* Python 2.7

* Additional Python libraries:

  * cv2

  * skimage

  * imageio

This repository contains five python scripts:

1. DE_SSIM.py

   This script uses Average SSIM as the fitness function.  

   Input: JPEG images (frames from a video)  

   Output: GIF image containing all the extracted key frames.

  

2. DE_Entropy.py

   This script uses Average Entropy Difference as the fitness function.  

   Input: JPEG images (frames from a video)  

   Output: GIF image containing all the extracted key frames.

  

3. DE_Euclidean.py

   This script uses Average Euclidean Distance as the fitness function.  

   Input: JPEG images (frames from a video)  

   Output: GIF image containing all the extracted key frames.

  

4. DE_LIVE.py

   This script uses Average Euclidean Distance as the fitness function. It extracts key frames from a live video,

   it will output a GIF image containing the extracted key frames periodically 

   (depending on how many frames to read and number of key frames required).  

   Input: JPEG images (output from capture_xframes)  

   Output: GIF image containing all the extracted key frames.

  

5. capture_xframes.py

   This script captures webcam stream and saves the frames as JPEG files.
