Abstract

The purpose of this paper is to provide a compact overview of the state-of-art image mosaic algorithms in commercial softwares and to propose objective assessment method of that. Among them, several algorithms, widely used and high quality, result in the mosaic image by applying to seven different kinds of seasons of KOMPSAT-2 images and then consequently each result is analyzed visually. Moreover, quality index is suggested to assess the similarity with colors regarding adjacency images and then it is performed by comparing and analyzing the visual and quantitative results. Consequently, we found out the suggested quality index is feasible.

본 연구의 목적은 최신 상용 소프트웨어에서 지원하고 있는 영상 모자이크 기법을 비교 분석하고, 제작된 모자이크 영상들의 정량적인 품질평가 방법을 제시하는 것이다. 상대적으로 뛰어난 성능을 나타내는 것으로 알려져 있는 모자이크 기법을 계절적 특성이 서로 다른 7장의 KOMPSAT-2 위성영상에 적용하였고, 각각의 결과를 시각적으로 비교 분석하였다. 또한, 제작된 모자이크 영상의 성능을 비교 할 수 있는 정량적 평가지수를 제안하고, 시각적 결과와 비교 검증을 수행함으로써 제안된 품질평가 지수의 적용 가능성을 제시하였다.
