SRgen (mosaic generator)

SRgen is a tool that allows you to construct an image from another image serving as a pattern.

Building

To build C version, simply run:

clang -Ofast -march=skylake-avx512 src/SR.c -o bin/SR
# or with gcc / MSVC

Usage

Running C version:

./bin/SR --in input_image.bmp --pattern pattern_image.bmp --out output_image.bmp

C version only works with BMP images in BGR24 format!

Running with many frames

To run the application over multiple frames, you can specify input/output path as formatted path, i.e.

# ffmpeg -i Video.mp4 -pix_fmt bgr24 frames/frame%04d.bmp
./bin/SR --in frames/frame%04d.bmp --pattern VanGogh.bmp --out out/frame%04d.bmp
# ffmpeg -framerate 29.97 -i out/frame%04d.bmp Result.mp4
