Web13 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: An image size can be changed in several ways. One of the simpler ways of increasing image size is nearest-neighbor interpolation, replacing every pixel with the nearest pixel in the output; for upscaling this means multiple pixels of the same color will be present. This can preserve sharp details in pixel art, but also introduce jaggedness in previously …
