# Tools
## Tile division ABG Remover
This tool is based on Anime Remove Background(https://huggingface.co/spaces/skytnt/anime-remove-background) and ABG_extension(https://github.com/KutsuyaYuki/ABG_extension).

Post-processing is added for more precise cropping based on the mask image generated by Anime Remove Background.

In this post-processing step, the input image is divided into a specified number of tiles, and the pixels in each tile are clustered based on color information.
