interp

This function provides 2D and 3D (linear or cubic) interpolation for pixel values.
Locations need to be provided as a data.frame with variables x,y,z, and c (the last two are optional).

Fast image processing for images in up to 4 dimensions (two spatial
dimensions, one time/depth dimension, one colour dimension). Provides most
traditional image processing tools (filtering, morphology, transformations,
etc.) as well as various functions for easily analysing image data using R. The
package wraps 'CImg', <http://cimg.eu>, a simple, modern C++ library for image
processing.
