What is ImageJ?
ImageJ is an open source image processing program for multidimensional image data with a focus on scientific imaging.
What can ImageJ do?
- a user interface with functions to load, display, and save images
- basic image processing functionality
- a wealth of advanced image processing techniques, including colocalization, deconvolution, registration, segmentation, tracking, visualization and much more.
- an extension mechanism including support for plugins and macros
ImageJ's extensibility is truly the root of its effectiveness: many advanced image-processing methods are not provided by the core application, but rather made available as third-party plugins via update sites written by specialists in the corresponding fields.
