Real Median Filter and Over-Sharpening Restoration Dataset

This dataset contains 9734 reproducibly sampled anime images for image restoration.

Each row contains:

  • ref1: an artifact-degraded full-image reference generated from the original image. The artifact is created by CPU image processing, including median filtering, excessive sharpening, or both.
  • target: the original clean image, saved as lossless WebP by default.
  • edit_instruction: an English instruction asking the model to recover a natural clean image and remove filtering/sharpening artifacts.
  • metadata columns: source paths, captions, descriptions, degradation settings, dimensions, and seeds.

The dataset was generated with seed 251101.

metadata.jsonl uses ref1_file_name and target_file_name so Hugging Face ImageFolder can display two image columns in the Dataset Viewer.

This dataset is generated by CPU image processing only. It does not use model inference. WebP is used by default to reduce storage while keeping Hugging Face Dataset Viewer compatibility.
