본 논문에서는 입력으로 들어온 사람의 얼굴 영상으로부터 간략하면서도 인물의 특성이 잘 반영되도록 스타일화된 일러스트레이션 영상을 만드는 방법을 제시한다. 이를 위해 입력으로 들어온 영상으로부터 얼굴 영역 및 각 구성요소들을 인식하고, 그 결과를 효과적인 스타일화에 이용한다. 실제 스타일화는 크게 주요 부분을 간단한 톤으로 표현해주는 톤 그리기 부분과 해당 부분을 적은 선으로 효과적으로 묘사하는 선 그리기 부분으로 나뉘며, 이 두 부분에 머리카락이나 옷 부분 등에 추가적인 효과를 더하여 이루어진다. 이러한 스타일화 과정은 일반적으로 사람이 그린 그림과 같이 극도의 추상화 과정을 거쳐 보다 적은 표현으로 대상의 특징을 잘 살려주는 것을 목적으로 한다. 이를 위해 여백을 살리는 간단한 표현으로도 대상을 효과적으로 묘사하는 동양화 기법을 응용한다.
Abstract
We propose a stylized facial illustration method that expresses important features of a target highly abstractly but effectively from a human facial picture. Our method first detects facial components such as eyes and their associated regions from an input image, and then uses the detected results to render a stylized portrait. Our illustration method mainly consists of two key components and additional components: a tonal illustration component to draw simple tones, a line illustration component to draw a set of lines, and additional illustration components for hair, clothes, etc. The illustration part of the proposed method aims at illustrating features of a target effectively in a highly abstracted way like hand-drawn paintings. In order to achieve this goal, our method adopts an oriental black-ink painting style, which expresses objects effectively with empty spaces and simple expressions such as abstracted lines.
