본 논문은 프로그래밍 가능한 GPU를 이용한 포토 모자이크 생성 방법을 제안한다. 그래픽스 파이프라인을 통해 포토 모자이크를 생성할 수 있도록 정점을 디자인하고, 타일로 사용할 영상 데이터베이스의 텍스처 표현을 제시한다. 정점 셰이더에서는 텍스처에 저장된 입력 영상과 타일 영상 들을 이용해 최적타일을 찾고, 프래그먼트 셰이더는 이것을 프레임버퍼에 그림으로써 포토 모자이크를 생성한다. 본 논문에서 제안한 방법은 최적 타일을 찾는 기존의 포토 모자이크 알고리즘에 비해 월등히 빠른 결과를 보여 준다.
Abstract
We proposed the method for photomosaic generation using a programmable GPU. We design vertices to generate a photomosaic through a graphics pipeline and suggest a texture representation of an image database whice is used for tile. Both the source image and the tiles are stored to texture, which are matched by a vertex shader and drawn by a fragment shader. This is much faster than several techniques which achieve the best match for each tile.
