  • There are three major steps in image reconstruction: sample position mapping, pixel value interpolation, and compounding.
  • linear interpolation
  • spline interpolation
  • cubic spline interpolation

It is not just interpolation over the situations that you've encountered previously, like learning to drive in the US, right.

Examples

  • As before, some interpolation is necessary to determine the actual observed counts when observation times are irregular.

Morphology

interpolation = interpolate (semi-transparent) = inter + polate + ion

The noun is a regular suffixation of the verb 'interpolate', but the mathematical sense is a technical specialization of 'inserting/estimating between' and may not be fully predictable to all learners.

Etymology

Interpolation comes from the Latin parts inter- meaning 'between' and a root that meant 'to change or touch up', so it originally meant putting something into a space. In math, this became the idea of 'filling in' a gap by estimating a value that sits 'between' two known values.
