DRAGONFLY 30-DAY TRIAL

From straightforward visualization to advanced image processing and quantification, Dragonfly delivers the features you need to accomplish meaningful results quickly and confidently.

Featuring an easy-to-use user interface with intuitive workflows and an extensive set of tools for the multi-dimensional display, transformation, segmentation, registration, and measurement of multi-scale multi-modality image data, Dragonfly delivers qualitative and quantitative results for material characterization, structure properties, surface analysis, process evaluation, quality control testing, or any analysis function that requires a high-degree of accuracy.


Data Import

Dragonfly is the ideal framework for integrating data from multiple sources into a single environment. Importing images into Dragonfly is always easy, whether your images come from leading microscope and imaging hardware vendors or RAW files produced by academic software. Forget about file formats and focus on getting to work with the right images and the critical field-of-view.

Dragonfly supports the following file formats for 3D volumetric data:

  • Image stacks (.tif, .tiff, .jpeg, .jpg, .png, .bmp, .dib extensions).
  • DICOM image files (.dcm extension). New for version 3.0.
  • MRC (.mrc extension), REK (.rek extension), TXM* (.txm extension).
  • Analyze 7.5 files (.hdr extension with accompanying .img extension).
  • RAW data (.raw and .pic extensions) with or without header files (.dat extension).

*File format used by ZEISS Xradia 3D X-ray Microscopes. Available for Dragonfly Pro only.


Image Processing

Restore image quality and yield information that otherwise would have been missed with industry leading image filters, powerful post-processing functions, and infinite extensibility.

Dragonfly's extensive image processing toolkit features filters to smooth images, sharpen edges, correct uneven shading, extract features, and more. With selectable 2D and 3D settings and user-specified kernel sizes, you can combine multiple filters together as a workflow, which can be saved and applied to a batch of images for automated processing.

  • Smooth noisy images with Bilateral, Gaussian, Mean, Mean Shift, Median, Non-Local Means*, Percentile, and Rank filters.
