A content-adaptive representation of fluorescence microscopy images called Adaptive Particle Representation (APR), which replaces the regular grid of pixels with particles positioned according to image content. This overcomes storage bottlenecks, as data compression does, but additionally overcomes memory and processing bottlenecks, since the APR can directly be used in processing without going back to pixels.
