WebOct 8, 2010 · Image Interpolation (ba_interp2) % where method is one off nearest, linear, or cubic. % interpolate. % Z is a I_1 x ... x I_n x D matrix, which contains the interpolated image channels. % This method handles the border by repeating the closest values to the point accessed. % This is different from matlabs border handling. WebC. Bicubic Interpolation Bicubic interpolation is similar to bilinear interpolation algorithm. For the unknown pixel P in amplified image, its influence sphere is expanded to its 16 adjacent pixels, then the color value of P is calculated by these 16 pixels according to their distance to P.
