The piecewise bi-linear looks more accurate to the original if squinting your eyes, but the piecewise constant looks cleaner, if not very clearly pixelated.

what does bi in bi-linear mean?

Bilinear means linear in two directions. I think that means in this case the pixel values are being interpolated both horizontally and vertically.

Is there a standard to determine how "accurate" an interpolation is? I.e. Can we determine how much color or edges is preserved from the original image?
