Webb13 sep. 2024 · Method 2 - The Popular Way - Bilinear Interpolation. This is one of the most popular methods. The interpolation function is linear in X and in Y (hence the name – bilinear): where frac (x) is the fractional part of x. The resulting matrix is M [i,j]=blin (i/N,j/N). The color map representation is:
