Why ImageJ?

Powerful

ImageJ facilitates image analysis techniques including image processing, colocalization, deconvolution, registration, segmentation, tracking, visualization, and more.

Extensible

ImageJ offers robust extensibility, harnessing the power of hundreds of plugins to assist with your imaging needs.

Free & Open Source

ImageJ is an open source project hosted on GitHub, developed by and for the scientific imaging community.
