Nearest-neighbor interpolation

Nearest-neighbor interpolation is a simple method used for interpolation in multidimensional spaces, particularly in the context of image processing and data resampling. It is a technique for estimating values at certain points based on the values of neighboring points. ### Key Features of Nearest-neighbor Interpolation: 1. **Methodology**: - The algorithm works by identifying the nearest data point (in terms of distance) to the point where an estimate is desired and assigns that value to the new point.
