Simple end-to-end python script to make cool mosaic posters made from scenes extracted from movies

• Python
• OpenCV
• NumPy

python main.py --videoPath "PATH/TO/VIDEO.mp4" --posterPath "PATH/TO/POSTER.jpg"

Use high-resolution posters for best results.

Since this is a proof of concept which I hacked in an hour for fun, I used the most naive approach I could think of.

* Extract every nth frame from the video, resize it to (tx,ty) and store it in a directory
* Find colour histograms of extracted images and store them in a pickle file
* Iterate over the poster while comparing the histogram of every consecutive block of size (tx,ty) with the histograms stored in the pickle file. 
* Replace that block with the most similar scene. 

Feel free to experiment with different histogram comparison methods or image similarity measures.
