Most of IPSDK algorithms available manage 5 Dimensions (X,Y,Z, stack of images and color planes).These algorithms work on all image types: 8, 16 or 32 bits and floating images. All these features are automatically vectorized and distributable on PC cluster to ensure optimal execution speeds.This list is not exhaustive. It is simply the first identified features that will be available in initial versions of the product.Functions of the IPSDK library are available in C++ and Python.
