3D Image Processing: Process and Analyze 3D Images

Aphelion™ users can now effectively process and display 3D images using virtually the same processing and analysis power provided for 2D images. The Aphelion™ Imaging Software Suite includes two optional extensions for these functions: the 3D Image Display Extension and the 3D Image Processing Extension. Using these powerful extensions, images acquired from sensor devices such as X-ray Micro-CT, 3D Atom Probe, confocal microscopes, medical scanners, and other 3D devices, can be easily processed, analyzed, and displayed using the Aphelion™ Dev Graphical User Interface.

The Aphelion™ 2D image processing operators have been enhanced to handle 3D data including, for example, convolution, addition, subtraction, maximum, erosion, dilation, distance function, labeling, watershed, and threshold. The 3D Image Processing extension includes analysis on 3D images and true 3D Objectsets. A set of specific 3D measurements is available such as sphericity, surface area, and volume.
