+# imgutils-models
+
+This repository includes all the models in [deepghs/imgutils](https://github.com/deepghs/imgutils).
+
+## LPIPS
+
+This model is used for clustering anime images (named `差分` in Chinese), based on [richzhang/PerceptualSimilarity](https://github.com/richzhang/PerceptualSimilarity), trained with dataset [deepghs/chafen_arknights(private)](https://huggingface.co/datasets/deepghs/chafen_arknights).
+
+When threshold is `0.45`, the [adjusted rand score](https://scikit-learn.org/stable/modules/generated/sklearn.metrics.adjusted_rand_score.html) can reach `0.995`.
+
+File lists:
+* `lpips_diff.onnx`, feature difference.
+* `lpips_feature.onnx`, feature extracting.
+
+## Monochrome
+
+These model is used for monochrome image classification, based on CNNs and Transformers, trained with dataset [deepghs/monochrome_danbooru(private)](https://huggingface.co/datasets/deepghs/monochrome_danbooru).
