Abstract

In this paper, we proposes a method that analyzes the characteristics and patterns of color juxtaposition based on the color wheel used by pointillism painter and an algorithm that generates pointillistic images by applying obtained analysis data. In order to analyze color juxtaposition of pointillism, we extract the stroke colors of real painting and find the most similar probability density functions(PDFs) through applying good-of-fit tests for the probabilistic distribution of stroke colors. By performing the juxtaposition of color based on the found PDFs, we can convert input image to pointillistic image effectively. It can be seen that this study shows reliability in the use of data obtained from actual paintings and that leads to perform a reasonable work.

본 논문에서는 점묘주의에서 화가들이 사용했던 색상이론을 기반으로 색상병치의 특징 및 패턴을 분석하고 얻어진 분석 데이터를 회화적 렌더링에 적용해 점묘화를 생성하는 알고리즘을 제안한다. 점묘화의 병치를 분석하기 위해서, 실제 작품에 나타나는 스트로크의 색상을 추출하고 그 색상의 분포도를 잘 알려진 확률분포함수와 적합도 검정을 통해 최적의 분포도 함수를 얻는다. 이러한 분포도 함수를 이용해 색상 병치를 함으로써 2D 입력영상을 점묘화풍의 영상으로 효과적으로 변환할 수 있었다. 우리의 연구는 실제 작품을 통해 얻어진 데이터를 사용함으로써 보다 신뢰성이 있으며 합리적이라고 할 수 있다.
