go-mosaic

go-mosaic is a tool for making photo mosaics. Photo mosaics, or montage photos, montage collages, are an art technique of image processing. Pictures made in this way are composed of many small photos when viewed close, but when viewed from a distance, each photo Through the fine-tuning of light and shadow and color, the basic pixels of a large picture are called the photo mosaic technique

Features

• Designed for massive pictures, can support millions of pictures
• Built-in cache database, pictures are deleted and changed automatically from cache
• Multi-core construction, loading, calculation and replacement are all concurrent

Use

• Clone the project, compile, or download release
• Execute commands and wait for completion

go-mosaic.exe -src input.png -target output.jpg -lib ./test

• Among them, ./test is the picture folder, which is used to form the elements of the final picture. input.png is the target image, which is used to generate the final large image output.jpg. The more material pictures, the more accurate the generation
