We have a linear interpolation example, and it mentions that a 50% interpolated point, but the image shows 75%. We should probably also mentioned the interpolated point, or maybe label the ...

Explanation: Bilinear Interpolation takes into account 4 points, with known "height" value, to approximate a 5th point's "height" value. The 5th point must be contained within the bounds formed by the ...

Abstract: We present a simple, original method to improve piecewise linear interpolation with uniform knots. We shift the sampling knots by a fixed amount, while enforcing the interpolation property.

Abstract: This paper presents an interpolation method based on shifted versions of two piecewise linear generators, which provides approximation order 2 like usual piecewise-linear interpolation; i.e.
