说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)
