Abstract

In this paper, we propose a noise estimation method using edge detection. It is a filter-based noise estimation method. Edge detection is to exclude structures and details which have an effect on the noise estimation. To detect edge, we use a modified rational filter which is robust to details of images. The proposed noise estimation method is more efficiently applied to noise estimation in various types of images and has better results than those of conventional filter-based noise estimation methods.

본 논문에서는 에지 검출을 이용한 잡음 예측 방법을 제안하였다. 이 방법은 필터 기반으로 한 잡음 예측 방법이다. 에지 검출은 잡음 예측에 영향을 미치는 구조나 세밀한 정보들을 제거하기 위함이다. 에지 검출을 하기 위하여, 영상의 세밀함에 안정적인 수정한 래셔널 필터를 사용하였다. 제안한 잡음 예측 방법은 다양한 형태의 영상들의 잡음 예측에 더욱 효율적으로 적용되며 기존의 필터 기반으로 한 잡음 예측 방법들보다 좋은 결과를 얻는다.
