摘　　要：图像的双线性插值是图像处理中常用到的一种图像放大方法,传统的彩色图像的双线性插值没有考虑到彩色图像三个分量之间的内在有机联系,容易造成不协调的色彩,本文从颜色感知均匀性角度出发,提出一种新的基于矢量方法的彩色图像双线性插值算法,实验结果表明新的基于矢量方法的彩色图像双线性插值算法有效性。Bilinear Interpolation has been frequently used to magnify images as a method of image processing. The traditional ways of Bilinear Interpolation fail to consider the intrinsic relations among the 3 components of color images, which results in inconsistent colors. According to the uniformity of color perception, the paper brings forward a novel color-image bilinear interpolation algorithm based on the method of vector. The experimental results had shown that the proposed algorithm is of efficiency.
