In-phase Statistical Edge Directed Interpolation based on Windowed MMSE Estimation

MMSE관점에서 위상 정합 방향성 경계 강조 보간법

In this paper, we present an improved novel interpolator that performs high quality interpolation on both synthetic and real world images. Its structure, which is based on a four directional linear predictor with equiripple windowed samples and phase matching equalizer, provides edge-directional data interpolation so that sharp and artifacts-free images are obtained at a reasonable computational cost.
