function z_interp = bilinear_interpolation(z, x, y) % z是原始数据矩阵 % x和y是要插值的点的坐标 % 获取矩阵大小 [rows, cols] = size(z); % 找到包含点(x, y)的四个相邻网格点 x1 = floor(x); x2 = min(ceil(x), cols); y1 = floor(y); y2 = min(ceil(y), rows); % 计算dx...
As shown in FIG, the pixel values of f1 and f2 are respectively obtained by a linear interpolation, and then the pixel values of f are obtained by linear interpolation for f1 and f2. This is the principle of bilinear interpolation. We can use the following formula to show the process of...

双三次插值法(Bicubic Interpolation)是一种在图像处理中常用的图像重采样方法。它比双线性插值法(Bilinear Interpolation)更复杂,但可以提供更好的图像质量。双三次插值法的原理是:在原始图像中,以目标像素为中心,取其周围16个像素的灰度值,根据双三次多项式函数进行拟合,计算出目标像素的灰度值,以实现图像...
