Matlab之双线性插值'bilinear' 双线性插值‘bilinear’ 查了网上的很多资料,我觉得双线性插值就是最近邻插值(这是我自己理解的最近邻插值)的升级版。我们计算的坐标点为小数的时候,为了得到更合理的灰度值,我们用最近四个点的灰度值来估计这个小数坐标的灰度值。数学推导我就不写了,难地写也难得看,具体原理我用图...
is an interpolation of the data on the boundaries of the matrix. The data on the boundaries is defined by the four vectors with the obviously equal "corners". The data in the boundary vectors isn't necessarily monotonic. Are there functions in matlab that can do this type of interpolation?

opencv和Matlab中的双线性插值 这部分的前提是,你已经明白什么是双线性插值并且在给定源图像和目标图像尺寸的情况下,可以用笔计算出目标图像某个像素点的值。当然,最好的情况是你已经用某种语言实现了网上一大堆博客上原创或转载的双线性插值算法,然后发现计算出来的结果和matlab、openCV对应的resize()函数得到的结果完...
提供了一个MATLAB函数示例，用于实现双线性插值，虽然还未全面考虑所有参数，但考虑到矩阵计算量不大，将其转换为C++语言也相对容易实现。最后，附上使用双线性插值法处理图像变换后的效果示例，此次变换采用了投影变换。通过实际操作，我们可以直观地看到双线性插值在图像尺寸调整及复杂变换场景下的应用效果。
