pyPhotoMosaic

pyPhotoMosaic lets you create photomosaics in a few steps.

Trying to optimise the efficiency of the code to reduce build time.

Example:

Original & Output (CV2)

Original & Output (PIL)

Artist: https://www.pixiv.net/artworks/96381546

Updated to use pure OpenCV for image manipulation

Benchmark Params: TILE_SIZE = 80, ENLARGE_FACTOR = 8, REUSE_CACHE = FALSE

• Old PIL processing time: 3m 03.70s total
• New CV2 processing time: 2m 14.98s total

Prerequisites

• numpy
• cv2

Usage

Windows:

python pMos.py <target_image> <image tiles folder> <output_filename>

Linux & macOS:

python3 pMos.py <target_image> <image tiles folder> <output_filename>

It might take a while to create a the Photo Mosaics.

Parameters

• TILE_SIZE (Mosaic Tiles' sizes in pixels)
• CACHE_DIR (Mosaic Tiles' cache directory)
• TARGET_CACHE_DIR (Target Image's cache directory)
• REUSE_CACHE (True to reuse the cache, False to regenerate cache)
• ENLARGE_FACTOR (Factor to enlarge the image)
