nearest neighbor interpolation example

The interpolation function in MATLAB is interp1. The Calling format is: Yi = interp1 (X, Y, XI, 'method ') Where X and Y are interpolation points, Yi is the result of interpolation at the interpolation point XI; X and Y are vectors, and 'method'

Common interpolation methods 1. Nearest Element Method This is the simplest method of interpolation and does not need to be calculated. In the four adjacent pixels of the desired pixel, the gray scale of the adjacent pixel closest to the desired

Things are continuous, and time is continuous... the real world is mostly continuous. However, we can only observe discretization for two reasons: 1. If the storage space required for consecutive records is too large, it is like the records cannot
