Abstract

In this paper, we propose the auto correction technique of photography composition by which the eye line is concentrated and the stable image of the structure can be obtained in case the general user takes a picture. Because the general user photographs in most case without background knowledge about the composition of the photo, the subject location is not appropriate and the unstable composition is contrasted with the stable composition of pictures which the experts take. Therefore, we provide not the method processing the image after photographing, but he method presenting automatically the stable composition when the general users take a photograph. The proposed method analyze the subject through Saliency Map, Image Segmentation, Edge Detection, etc. and outputs the subject at the location where the stable composition can be comprised along with the guideline of the Rule of Thirds. The experimental result shows that the good composition was presented to the user automatically.

본 논문에서는 일반 사용자가 카메라로 사진을 촬영할 경우에 시선을 집중시키면서 안정적인 구도의 영상을 얻을 수 있는 자동 구도 제시기법을 제안한다. 일반 사용자는 대부분 사진의 구도에 대한 배경지식이 없이 사진을 촬영하고, 촬영된 사진은 피사체의 위치가 적절하지 않아 전문가들이 촬영한 안정적인 구도의 사진과 대조된다. 따라서 비전문가 사용자들에게 촬영 후 영상을 처리하는 방법이 아닌 촬영 시 안정적인 구도를 자동으로 제시해주는 방법을 제공한다. 제안하는 방법은 Saliency Map, Image Segmentation, 윤곽선 검출 등을 통해 피사체를 분석하고 피사체를 안정적인 구도가 구성될 수 있는 위치에 황금분할 가이드라인과 함께 출력한다. 실험결과를 통해 피사체를 분석하고 윤곽선을 검출하여 사용자에게 자동으로 구도가 제시되는 것을 알 수 있다.
