  • Robust Laughter Segmentation with Automatic Diverse Data Synthesis Reviewed

    Laughter detection is important in the analysis of human communication. In recent years, machine learning has been commonly used to detect laughter. Laughter segmentation, the task of accurately identifying the location of laughter in audio, necessitates precise annotation of training data. However, manual annotation is very time-consuming and data preparation is not easy. We propose a method to facilitate the creation of training data for segmenting laughter in audio. Our method automatically annotates by synthesizing laughter and adding it to arbitrary audio. It allows a large amount of data to be created because the number and positions of laughs can be set freely, and data augmentation can be applied to the laughter separately. In addition, because our method can automatically annotate arbitrary audio, it can easily create datasets for training models on new data. Evaluation shows that our segmentation model outperforms existing models trained on manually annotated datasets.

  • Hand‐drawn anime line drawing colorization of faces with texture details Reviewed International journal

    Automatic or semi-automatic colorization can reduce the burden of illustrators in color illustration production, which is a research area with significant market demand. Texture details in eyes and hair influence the impression of character illustrations. Generally, these details are not expressed in line drawings. Many existing automatic or semi-automatic colorization methods do not target hand-drawn line drawings and it is difficult to paint texture details on such drawings. In this paper, we propose the semi-automatic colorization of character line drawings around faces with texture details. Our method uses a reference image as a color hint and transfers the textures of the reference image to a line drawing. To achieve this, our method uses semantic segmentation masks to match parts of the line drawing with the same parts of the reference image. We create two types of segmentation datasets to train a segmentation network that creates segmentation masks. We transfer texture details to a hand-drawn line drawing by mapping each part of the reference image to the corresponding part of the line drawing using segmentation masks. We show that our method is more effective for hand-drawn line drawings than existing methods using qualitative and quantitative evaluations.

  • Global Illumination-Aware Stylised Shading Reviewed International journal

    Our aim is to convert an object's appearance to an arbitrary colour considering the light scattering in the entire scene, which is often called the global illumination. Existing stylisation methods convert the colour of an object with a 1-dimensional texture for 3-dimensional computer graphics to reproduce a typical style used in illustrations and cel animations. However, they cannot express global illumination effects. We propose two individual methods to compute the global illumination and convert the shading to an arbitrary colour. The methods reproduce reflections in other objects with the converted colour. As a result, we can convert the colour of illumination effects that have not yet been reproduced, such as soft shadows and refractions.

    CG 向けに最適化された安定性の高い既存の流体シミュレーション手法は美しくリアルな視覚結果をもたらすが,それらは特定の物理的条件を満たすように作られており,幾何学的に不自然な視覚結果を出力することがある.これを解決するために,流体の挙動を幾何学的手法で近似する考え方に基づき,適切な数理モデルを開発することが考えられ,視覚的・幾何学的に自然な流体挙動を少ない計算量で得られるメリットが見込まれる.本研究ではシミュレーションされた流体の渦場を局所的に二次形式の関数で近似する手法と,近似結果を利用した渦場の様々な幾何学特徴の抽出手法を提案する.本手法で流体内の 1 点の近傍での二次形式の幾何学(楕円,放物線,双曲線)の構造を判別し,結果が楕円である場合に渦の形状と相性の良い特徴(楕円の中心位置,縦横比など)を抽出する.また,その幾何学特徴と流体の物理的特徴の関連性も調査し,楕円なら渦の中心付近,放物線または双曲線なら流れの歪みの関連性が高いことを示す.さらに本手法の応用として流体の渦の細部を上げる既存手法を修正し,よりリアルで幾何学的整合性が良い渦場を作ることに成功した.

    本研究では二次元流れ模様の生成、正確性と演出性と操作性の向上、それらの裏付けとなる現象のモデリングの効率化、また、これらを駆使して制作者の意図が反映されやすい流れ模様を自由に美しく生成する方法を確立する。
    CG(Computer Graphics)における流体計算には必然的にCFDの計算方法がベースとなる。したがって、これをいかに最適化し簡略化するかが論点となる。人間が直観的に理解できるボリューム空間表現は断面であるとことからレンダリングの対象を二次元に限定することは合理的であると考える。不可視の部分の動きを簡略化できれば二次元の流れ模様をより自然に美しく描出可能であると考えている。
