【摘要】 为了解决数字图像插值过程中出现的边缘模糊和锯齿现象,提出一种改进的多方向融合图像插值算法。该算法将图像分为平坦区域和边缘区域,平坦区域采用双线性插值算法进行插值,边缘区域采用多方向融合算法进行插值。实验结果表明,该算法运算复杂度小,其结果在主观视觉效果和客观指标方面都有很大的改善,且适用于任意倍数的插值放大。更多还原

【Abstract】 To reduce the edge blur and sawtooth of image appeared in the process of image interpolation,an improved image interpolation algorithm using six directions of data fusion is proposed.First,an image is divided into flat areas and edge regions,then,bilinear algorithm is used in the flat areas,and the proposed algorithm with directions of data fusion is used in the edge regions.Experiments show that,the computation complexity of this proposed algorithm which has improved on both subjective visual effect and objective indicators is small.Moreover,it can be applied to any multiples of interpolation amplification.更多还原
