전 방향 에지 예측 기법을 이용한 De-interlacing 알고리듬

국문 초록 (Abstract)

본 논문은 전 방향 에지예측 기법을 이용한 De-interlacing 알고리듬을 제안한다. 본 논문에서는 기존의 DOI(Direction-Oriented Interpolation) 알고리듬을 기본 방법으로 사용 하였다. De-interlacing 방법은 크게 2단계로 나누어진다. 먼저 에지의 방향을 예측한 후, 잃어버린 화소 값을 에지의 방향에 따라 보간하는 방법이다. 본 논문에서는 고각도 에지를 고려한 DOI 알고리듬을 통하여 에지를 예측한 후 잃어버린 화소값을 중간값(median) 필터를 사용하여 보간한다. 실험 결과는 제안된 알고리듬이 기존의 알고리듬들 보다 객관적 및 주관적인 평가에서 우수함을 입증한다.

다국어 초록 (Multilingual Abstract)

This paper proposed a novel de-interlacing algorithm using all direction edges estimation technique. In the proposed algorithm, previously developed the DOI(Direction-Oriented Interpolation) algorithm was used as a basis. The de-interlacing method was divided into two main parts. First, we should estimate edge direction. Then, missing pixels were interpolated along with the decided edge. In this paper, after estimating the edge through the DOI algorithm considering high angle edge direction, missing pixels were interpolated by using the median filter. Experimental results indicate that the proposed algorithm is superior to the conventional algorithms in terms of the objective and subjective criteria.
