적외선 영상의 소형 표적 검출을 위한 배경 잡음 제거 방법

Abstract

The detection of small targets in infrared image is one of the most important issue in military field. However, it is a difficult task in complex background with various clutters. In this paper, a novel clutter suppression method based on discrete cosine transform(DCT) for small target detection is proposed. Experimental results show that the proposed method achieves better performance than conventional methods.
