In practice, simple interpolation methods, such as nearest-neighbor, linear, bilinear, and bicubic interpolation are most widely used. However, these methods usually yield an interpolated image with blurred edges, which degrade the perceptual quality of the image.
常见的插值方法有近邻插值、双线性插值、双三次插值等,计算量比较小,但是图像插值后常常出现方块效应或细节退化(边缘模糊)。
