Outline of Research at the Start

請者らは自然界や人間社会にある模様を模倣したNPRを数多く開発し,動画のNPRにおいてちらつきとシャワードア効果を抑制する方法も開発している.本研究では,さらに新しいタイプのNPRを開発し,これまでに申請者らが開発したNPRも含めて3D動画に適用する.
また,ユーザの利用用途に応じてNPRの効果的なパラメータや初期値を選択する際,ユーザの判断やアンケート調査などのような主観評価によって行われてきた.本研究では,NPRの視覚効果を眼球運動などの生理情報とアンケート調査などの主観情報を用いて深層学習で評価する新しいNPRの生理心理評価の方法を開発する.

Outline of Final Research Achievements

In this research, we developed a new type of non-photorealistic rendering (NPR) and applied it to 3D videos, including the NPR developed by the applicants. Specifically, we developed a method to generate flicker-free moire-like videos from RGB-D videos.
We also investigated a method for evaluating NPR images from physiological and psychological aspects using an eye tracker. The results of the experiment showed that it is possible to estimate the parameter values that make subjects look better when generating an NPR image by arranging two NPR images side by side.

Academic Significance and Societal Importance of the Research Achievements

新しいタイプのNPRを開発し,NPRを3次元動画に適用する研究は,動画専用カメラやステレオカメラを搭載したスマートフォンの今後の普及を先取りしたものである.3次元動画のNPRに関する研究は,デザインやアミューズメント,エンターテイメントの分野で活用できる.また,個人情報保護や情報セキュリティの観点からSNSやWebsiteなどで人や商品,看板を特定されたくない場合,単にぼかしやモザイクではなく,本研究の成果を用いればアーティスティックな表現が可能となる.
NPRの生理心理評価は,デザイン分野全体に世界的なインパクトを与える.また,デザイン学のみならず情報学の分野にも大きく貢献できる.
