Sketch2Manga: Shaded Manga Screening from Sketch with Diffusion Models

no code implementations13 Mar 2024 Jian Lin, Xueting Liu, Chengze Li, Minshan Xie, Tien-Tsin Wong

Unfortunately, there is no existing method that tailors for automatic manga screening, probably due to the difficulty of generating high-quality shaded high-frequency screentones.

Instance-guided Cartoon Editing with a Large-scale Dataset

no code implementations4 Dec 2023 Jian Lin, Chengze Li, Xueting Liu, Zhongping Ge

Cartoon editing, appreciated by both professional illustrators and hobbyists, allows extensive creative freedom and the development of original narratives within the cartoon domain.

Manga Rescreening with Interpretable Screentone Representation

no code implementations7 Jun 2023 Minshan Xie, Chengze Li, Tien-Tsin Wong

To overcome these limitations, we propose a novel interpretable representation of screentones that disentangles their intensity and type features, enabling better recognition and synthesis of screentones.

Video Colorization with Pre-trained Text-to-Image Diffusion Models

no code implementations2 Jun 2023 Hanyuan Liu, Minshan Xie, Jinbo Xing, Chengze Li, Tien-Tsin Wong

In this paper, we present ColorDiffuser, an adaptation of a pre-trained text-to-image latent diffusion model for video colorization.

Improved Diffusion-based Image Colorization via Piggybacked Models

1 code implementation21 Apr 2023 Hanyuan Liu, Jinbo Xing, Minshan Xie, Chengze Li, Tien-Tsin Wong

Our key idea is to exploit the color prior knowledge in the pre-trained T2I diffusion model for realistic and diverse colorization.

Neural Recognition of Dashed Curves With Gestalt Law of Continuity

no code implementations CVPR 2022 Hanyuan Liu, Chengze Li, Xueting Liu, Tien-Tsin Wong

While humans can intuitively recognize dashed curves from disjoint curve segments based on the law of continuity in Gestalt psychology, it is extremely difficult for computers to model the Gestalt law of continuity and recognize the dashed curves since high-level semantic understanding is needed for this task.

Invertible Tone Mapping with Selectable Styles

no code implementations9 Oct 2021 Zhuming Zhang, Menghan Xia, Xueting Liu, Chengze Li, Tien-Tsin Wong

In this paper, we propose an invertible tone mapping method that converts the multi-exposure HDR to a true LDR (8-bit per color channel) and reserves the capability to accurately restore the original HDR from this {\em invertible LDR}.

User-Guided Line Art Flat Filling With Split Filling Mechanism

no code implementations CVPR 2021 Lvmin Zhang, Chengze Li, Edgar Simo-Serra, Yi Ji, Tien-Tsin Wong, Chunping Liu

We present a deep learning framework for user-guided line art flat filling that can compute the "influence areas" of the user color scribbles, i. e., the areas where the user scribbles should propagate and influence.
