Tricubic interpolation
Tricubic interpolation is a way of finding what a missing location should be based on the values of the surrounding locations.
Imagine you have a set of points on a graph, and you want to figure out what the value would be at a new point that isn't on the graph. One way to do this is linear interpolation, where you draw a line between two points and use that line to make an estimate. Tricubic interpolation is a much more complicated way of doing this that can make much more accurate estimates.
To understand how tricubic interpolation works, imagine you have a 3D grid of evenly spaced points representing some kind of data, like temperature or color. Tricubic interpolation finds the value at a new point by using the values of the nearest 64 grid points (in a cube that surrounds the new point), and then doing a complex calculation to figure out what the value at the new point should be based on those surrounding values.
This calculation involves taking into account the spatial relationships between the surrounding points, so that points that are closer together have a bigger impact on the final estimate than points that are farther away. It also involves smoothing the data in a way that accounts for any noise or irregularities in the original measurements.
Overall, tricubic interpolation is a highly technical and mathematical tool used by scientists, engineers, and data analysts to make more accurate predictions about unknown values based on existing data.
