node-itk/example/nodeGetAverageSliceImageFilter.js

ITK is an open-source, cross-platform system that provides developers with an extensive suite of software tools for image analysis. Among them, Node-ITK is a node.js wrapper which built on top of ITK, intended to facilitate its use in rapid prototyping, education, and web servies for Medical Image Processing.Its Origins by My master thesis--jolly, a new Framework for Medical Image Processing
