Photo Mosaic (Added limited support for video)

Requirements

Python 3, OpenCV 4(pip install opencv-python ), Numpypip install numpy, tqdm (pip install tqdm )

How to Use

1. Clone or Download Repo
2. Prepare images to create mosaic [and add to the folder called images] (about 20,30 works. More images of different color leads to better mosaics).

• Note: Use this to create sample images from video

  (https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video)

3. Open CMD in the repo location and run mosaic.py python mosaic.py (https://www.thewindowsclub.com/how-to-open-command-prompt-from-right-click-menu/)

• For Multithreaded, see example below

• Note: If you want the above command to work, copy your image into the folder and rename it to me.jpg and add other image samples in the folder called images

• Use -i [path] flag to add your content image

• Use -d to add you datasets of images

• Use -r to division of the image (Optional) . Default is 32. Higher value leads to better picture but it takes more time.

• Use -s to specify size of output (Optional)

• Use -o [path] to save image. (Add filename with path)

Note: MultiThreaded is faster but does not produce as good result as single threaded

Example

python mosaic.py -i dicaprio.jpg -r 50 -o diCaprio_mosaic.jpg OR python mosaic_multiThreaded.py -i dicaprio.jpg -r 50 -o diCaprio_mosaic.jpg

Input

MultiThreaded Ouptut (-r 90)

python mosaic.py -i me.jpg -r 64 -d ./images -s 600 600 -o ./output.jpg

Input
