Every output pixel is replaced by its nearest pixel in the input. In 1 dimension, the value at x is the value of its nearest point. The blue line is the nearest-neighbor interpolation of the red dots.

WebSep 13, 2024 · Method 1 - The Simple Way - Nearest Neighbor Interpolation. The simplest interpolation strategy is just to take the value from the nearest data point. It could also be called "zero degree interpolation" and is described by the function: nni(x,y)=V round(x),round(y). The output matrix is simply generated by M[i,j]=nni(i/N, j/N). WebNov 4, 2024 · Why does this matter? Well, it means that if you shrink this image down just by using nearest-neighbor interpolation, which is the way MATLAB has always displayed images previously, you'll see some strange artifacts. Below, I'll use imshow to display the image at 25% magnification. imshow(A_cropped, 'InitialMagnification',25)
