Novel multi direction optimization interpolation based on edge max gradient algorithm
基于边缘最大梯度的多方向优化插值算法

Based on the conventional interpolation image,high-resolution image's edges were obtain using edge detector method.If the image was combined by RGB,color fusion should be processed first.Then optimized the edge's neighbors based on max-gradient character of the edge's multi-direction.Multi-time magnification uses small step-up ratio method.Ex- perimental results demonstrate that this algorithm model is terse and realizable easily,the blur and jaggy of image detail are avoided.The visual quality of the color interpolated images is more prominent.
