Webtoon Lineart Cropper with Filtering by Head-or-Face Detection

Upload a PNG lineart image of your webtoon and automatically crop the character's face or head included region. This demo leverages some detectors to precisely detect and isolate characters. The app will display cropped objects, provide a ZIP of cropped PNGs, and a PSD file with transparent lineart and half-transparent yellow-filled box layers. We provide two detectors to choose from, each with different filtering methods.

• Detector 1: Uses imgutils.detect and VLM-based filtering with google/gemma-3-12b-it

• Detector 2: Uses imgutils.detect and tag-based filtering with SmilingWolf/wd-eva02-large-tagger-v3

Note 1: The app may take a few seconds to process the image, depending on the size and number of characters detected. The example image below is a lineart PNG file created synthetically from images on Danbooru after lineart extraction.

Note 2: This demo is developed by Kakao Entertainment's AI Lab for research purposes, specifically designed to preprocess webtoon image data and is also not intended for production use. It is a research prototype and may not be suitable for all use cases. Please use it at your own risk.
