ImgLib2

It is a general-purpose, multidimensional image processing library. It provides an interface-driven design that supports numeric and non-numeric data types (8-bit unsigned integer, 32-bit floating point, etc.) in an extensible way. It implements several data sources and sample organizations, including one single primitive array, one array per plane, N-dimensional array "cells" cached to and from disk on demand, and planes read on demand from disk.
