Suppose that an input image f1 (128x128) is zoomed by a factor of 4 to obtain an out image f2 (512x512). Assume the pixel intestines f1(38,28) = 48, f1(38,29)=56, f1(39,28)=40, and f1(39,29) = 48. The first subscript of the pixel is row number and the second subscript is column number. Estimate the pixel intensity, f2(155,113) using 1) Nearest neighbor interpolation 2) Bi-linear interpolation
