在对隔行扫描、四叉树和Baptista算法分析的基础上,提出了一种基于交互式的图像生成插值算法。该算法首先对图像进行均匀取样,然后基于待插像素点的邻域像素值分布的几何特征,对像素点进行评估以决定像素点的值。经过上述4种算法的对比实验,结果表明,采用插值算法,仅由较少的数据量,即可生成较清晰的图像。

In this paper,based on the analysis of interlaced image,quadtree and Baptista algorithm,the authors presented an interpolation algorithm for interactive image generation: Firstly,sample evenly on image,then evaluate the pixel's value according to the distribution geometry characteristics of pixel's neighborhood.After the comparison among the four algorithms,the experimental results show that interpolation algorithm can generate high quality images with less data.
