본 논문에서는 중첩되는 영상사이의 평면 투영 변환을 구하는 방법을 제안하였다. 제안한 방법은 정규상관과 직사각형-사변형 평면 투영 변환에 기반 한다. 블록 정합을 이용하여 전역 이동을 계산하고, 중첩되는 영역의 정규 상관 계수 값을 최대로 하는 4개의 대응점을 찾기 위하여 가우시안 영상 피라미드에서 SA(simulated annealing) 알고리즘을 사용하였다. 이들 대응점에서 직사각형-사변형으로의 사상을 이용하여 평면 투영 변환을 계산하고, 마지막으로 중첩되는 영역의 RGB 컬러 값을 선형 가중치에 의해 혼합하였다. 실험으로 세 장의 영상을 한 장읠 큰 모자익 영상으로 합성하는 결과를 보였다.
