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.

Extract clusters whose mask image content exceeds a threshold value as foreground.

Parameters

• horizontal split num: Number of horizontal tile divisions.
• vertical split num: Number of vertical tile segments.
• n_cluster: Number of clusters based on color information.
• alpha threshold: Transparency of the mask considered as foreground.
• mask content ratio: Threshold for how much mask a cluster should contain to be considered foreground.

CascadePSP

This tool is based on CascadePSP(https://github.com/hkchengrex/CascadePSP).

Installation
