Abstract

In this paper, we present a spatial domain error concealment method to recover a lost block in intra-coded frames. The edge directions of the lost block are estimated by the difference values of the border pixels of the accurately received blocks. The lost block is interpolated according to the estimated edge directions. Our algorithm can adaptively recover a lost block according to the estimated edge direction. The distances between pixels are used as weights for interpolation. In spite of the low computational cost, the proposed method outperforms the previous methods in objective and subjective qualities.

본 논문에서는 프레임내의 정보를 이용하여 손실 블록을 복구하기 위한 공간 영역의 손실 블록 복구 방법을 제안한다. 손실 블록에 이웃하는 정확하게 수신된 블록들의 경계 화소의 차분값에 의해서 손실 블록이 에지 영역인지 평탄 영역인지를 판단하고 각각 다른 보간 방법을 적용한다. 에지 영역으로 판단되었을 경우 에지 방향을 추정하고 추정된 에지 방향에 따라 화소들 사이의 거리와 차분값을 가중치로 사용하여 적응적으로 손실 블록의 손실 화소들을 보간한다. 제안 방법은 이전 방법들에 비해 계산양은 적은 반면에 주관적 화질 비교에서 더 좋은 성능을 보이고 객관적 비교에서도 우수한 성능을 보인다.
