Abstract

In this paper, It propose a new restoration algorithm of high resolution, which is reconstructed to high resolution image using low resolution image informations. The proposed algorithm is constructed based on super resolution theory, it is consisted of progressive steps of the integration and construction. It reduced a lot of data-processing capacity and noise with integration through sub-pixel movement and wavelet basis through a higher resolution. As a result, it is shown that the main information is maintained and the error rate is improved. Using expansion fuzzy wavelet B-spline interpolation in stage of construction, it is confirmed that we can achieve smoothing image and good resolution without blur and block.

저해상도 영상 정보들 이용하여 고해상도 영상으로 재구성하는 새로운 고해상도 복원 알고리즘을 제안한다. 제안된 고해상도 복원 알고리즘은 super 해상도 이론을 바탕으로 구성되며, super 해상도는 정합과 복원의 순차적인 단계로 구성되어있다. 본 논문에서는 다해상도 분해를 통한 웨이브렛 기저와 하위픽셀이동을 통한 정합으로 많은 데이터 처리량과 잡음을 줄여 주요정보 유지와 에러율 개선하였다. 또한 복원단계에서는 퍼지 웨이브렛 B-스플라인 보간법을 이용하여 블러링과 블록화 현상이 없는 부드러운 영상과 해상도를 얻음을 확인하였다.
