SYNOPSIS

Free-D is a three-dimensional (3D) reconstruction and modeling software. It allows to generate, process and analyze 3D point and surface models from stacks of 2D images.

Free-D is an integrated software, offering in a single graphical user interface all the functionalities required for 3D modeling. It runs on Linux, Windows, and MacOS.

Free-D is developed by the Modeling and Digital Imaging team of the Institut Jean-Pierre Bourgin, INRA Versailles, France.

LATEST RELEASE: Free-D 1.14 (2017.02.20). See the major changes here.

FEATURES

Stack browsing

> can handle multiple stacks of several hundreds of Gb
> can handle section images of several hundreds of Mb
> supports variable inter-slice spacing and pixel calibration

Image segmentation

> manual delineation and pointing on 2D images
> automated 2D and 3D segmentation (contours, spots)
> segmentation editing, resampling, and smoothing

Image registration

> interactive rigid transformations (translation and rotation)
> several display modes for registration visualization
> registration based on images and/or segmentations

Model reconstruction

> instant rendering of segmentation and registration actions
> easy navigation through series of stack reconstructions
> permanent storage of poses of interest

Quantitative analysis

> quantitative measures (counts, lengths, areas, volumes, etc.)
> analysis per slice, per 2D item, per 3D reconstructed model
> export as spreadsheet for further statistical analysis

Spatial normalization and atlasing

> groupwise 3D shape registration and averaging
> linear and non-linear spatial normalization
> statistical density estimation and visualization
