character_similarity

This is a dataset used for training models to determine whether two anime images (containing only one person) depict the same character. The dataset includes the following versions:

Version	Filename	Characters	Images	Information
v0	images_v0.tar.xz	2059	162116	Crawled from zerochan.net, includes images of Arknights, Fate/Grand Order, Genshin Impact, Girls' Frontline, and Azur Lane, as well as over 1500 other game or anime characters. The images are all small preview thumbnails.
v0_tiny	images_tiny_v0.tar.xz	514	10036	The dataset `v0` has been simplified by randomly selecting 1/4 of the anime characters and 1/4 of the images for each character. It is recommended to use this dataset for model training and validation.
v0_xtiny	images_xtiny_v0.tar.xz	100	1814	`v0_xtiny` dataset is a further simplified version of `v0_tiny`, with only 100 characters retained. This dataset is only suitable for model validation and experimentation, and is not recommended for formal training.
v1	images_v1.tar.xz	4001	292800	The `v1` dataset is similar to `v0`, crawled from zerochan, but it contains a richer selection of characters and more diverse images of the same character. Each character includes no less than 3 and no more than 200 images.
v1_pruned	images_pruned_v1.tar.xz	3982	241483	Pruned from `v1` dataset, deleted monochrome and non-solo pictures, and also removed pictures where the character accounted for less than 40% of the entire vision area.
