利用低通滤波器对图像进行插值放大:按放大的倍数对原图像进行插零,插零后的图片与低通滤波函数进行卷积,原先插入的零的位置自动替换为适当的插值,如此图像就已经插值放大了,图像质量还不错。

... to use a piecewise linear interpolant. More difficult is when the curve is a parametric spline or pchip model. The interparc.m function uses an ode solver to integrate the distance along the curve itself, then uses that ode solver to do the interpolation.
