Analysis Pipeline

Analysis Pipeline - 2D/3D/4D Image Analysis  

arivis Vision4D is known for its capability to segment and track objects in data sets of any size. To achieve this, arivis Vision4D provides a robust and fast tool for processing of image data acquired from long-term time lapse experiments.
The Analysis Pipeline is a powerful solution with an intuitive interface for filtering and analyzing image data. The pipeline approach enables novice users to quickly run a pre-existing or newly built analysis workflows, while the image analysis expert is still empowered to create complex analysis routines.

Users can combine different Operators for filtering, segmentation and other analysis tasks in a simple and clear pipeline. Custom-defined analysis pipelines are processed interactively with many Operations providing preview options. Users can analyze large datasets in the quality of the results. Analysis results can be reviewed in 2D and 3D, or both simultaneously, with interactive charts and colouring options to facilitate interpretation. The interactive charts allow fast and easy selection of objects or population groups based on one or two features that can be collected from segmented objects.

Result tables are easily customized to include a range of built in and custom features than can be exported to XLS or CSV documents for further statistical analysis.
Charts and segmented images can be easily shared as graphics for presentations or publication through the one-click snapshot feature.


To facilitate the creation of quality pipelines while maintaining interactivity, arivis Vision4D makes it easy to work on subsections of a dataset without the need to crop and / or duplicate the data. The region selection can be based on built in pre-sets for the current view, plane or time point, or custom selection of ranges of times and planes within specific bounds.
Multiple pipelines can be run on the same datasets independently or in conjunction with other pipelines to permit more complex analysis or extract different features types from the same dataset.

Flexible pipeline execution

  • Combine different operators and filter methods (noise reduction, blur filters, contour filters, edge enhancement, etc.)
  • Preview the results of most operations directly on the image
  • Easily progress through all or part of the pipeline with rollback to test and adjust operational parameters
  • Immediate result visualization and live analysis report allows an evaluation and correction of parameters
  • The Blob Finder analysis operator is ideal for segmenting cells or any other type of rounded cell organelles

Viewing and Exporting Analysis Results

Along with preview options for many operations, the ability to immediately view results on the image makes it easy to evaluate the quality of the analysis. Object outlines are easily discernible in both 2D and 4D views, with advanced viewing options including custom colouring and transparency making it easy to contextualize the results. Image views, including objects, can easily be exported with 1-click snapshots or high resolution renders.
Along with visualization of the objects on the image, advanced data tables allow for precise interaction with the data through the Objects Window. Double-click an object in the Objects Window and immediately see it on the image, or select an object in the image to see it highlighted in the data table. The Objects Window is highly customizable, allowing users to view only relevant object features, with advanced graphing options based on time line progression, histogram distribution or even 2D distributions for easy population analysis. The Objects Window can be shown automatically after each segment operation for quick and easy review, or loaded on demand for an uncluttered workflow. And of course, the content of the Objects Window can easily be exported to statistical analysis packages along with other export options.

Proof reading and editing made easy

With arivis Vision4D users have powerful tools to refine automatic segmentations:

  1. Create objects manually: Draw a polyline around an object on consecutive 2D slices and arivis Vision4D will interpolate the complete object outline in 3D. This new manual segmentation tool is ideally suited to touch screen devices, e.g. tablets.
  2. Magic Wand semi-automatic object detection: Easily detect objects based on simple thresholds within a user defined region in one click. This tool works on both 2D and 3D views with depth awareness for easy interaction.
  3. Brush tool: Enable manual editing and work on segmented objects in sequential planes using the brush tool to fill in gaps or erase unwanted portion. Confirm your changes and the object is updated with its new features recalculated.

Measurements of Objects

The Objects window shows a wide range of measurement for the segmented objects. With the user selecting what measurements to include, there’s no cluttered tables with irrelevant measurements. The objects measurements are calculated dynamically and displayed in the Objects Window where they can be easily sorted. Custom object measurements allow to expand the characterization.

Common Features

arivis Vision4D offers the ability to measure using a range of measurement types, from 3D polylines to complex volumes and tracks. Each of these object types enable the collection of specific features, but also includes measurements that are independent of object type:

  • Rectangular or elliptical bounds of the object and their characteristics measured in either calibrated units or pixels (width, height, start/end position, etc.)
  • Centroids of objects based on geometry or bounding box
  • Temporal information relating to the position of an object within the dataset

Object Features

Along with measurements common to all object types, arivis Vision4D includes measurements specific to the types of objects in question:

  • 3D volumes
    • Intensities (mean, minimum, maximum, etc.)
    • Volume (with/without holes, calibrated/uncalibrated)
    • Surface area
    • Sphericity
  • Polylines
    • Length (total, segments)
    • Angles
    • Displacement
  • Tracks
    • Duration
    • Speed
    • Displacement
    • Straighness
  • Custom object features: Take any measurement of an object and create more complex measurements including:
    • Ratio of one measurement against another
    • Nearest object distance
    • Group statistics
    • Combinations of complex measurements


Flexible statistical and graphing tools allow users to get more from their data through grouping and without the need to export measurement tables to Excel.

  • Sort the Objects Window with one click according to any measurement
  • Change the units to make easier to read the results
  • Colour objects according to measurement value for easy pinpointing of outliers
  • Plot histograms of distribution and use 2D graphs to easily identify subpopulations
  • Combine objects into groups to quickly get more targeted statistics
  • Analyse parent/child relationships using segment colocalization
