WinRHIZO is an image analysis system specifically designed for root measurement in different forms. It can do morphology (length, area, volume...), topology, architecture and color analyses. It is made of a computer program and image acquisition components that can be combined to meet different needs and budgets.

WinRHIZO Basic, Reg, Pro and Arabidopsis Systems
for automatic washed root analysis.

Roots can be measured automatically by WinRHIZO when they are extracted from soil and washed of debris. Before analysis, they must first be digitized with a scanner or camera.

WinRHIZO standard systems uses a desktop optical scanner as the image acquisition device. They are well adapted to image acquisition of macroscopic objects like roots or leaves. Regent’s scanners come with:

  • Accessories to accelerate root positioning and scanning,
  • A special lighting system to avoid shadows (see below),
  • A permanent calibration to increase the measurement precision,
  • A manual and video that explain how to scan biological samples (root, leaves, seeds...) for analysis with our programs (scanning for scientific analysis is different than for artistic applications). It also gives tips specific to the scanner purchased (such as scanning speed vs. quality issues) .
WinRHIZO Basic WinRHIZO Reg WinRHIZO Pro WinRHIZO Arabidopsis
WinRHIZO Basic is a low cost entry level version. It produces only global measurements (average root diameter, total root length, area, volume and number of tips). WinRHIZO Regular has all features of the Basic model plus root morphology measurement as a function of user definable diameter classes. A root (length, area, volume) distribution graphic is automatically generated and is visible above the image. WinRHIZO Pro has all features of the Regular version plus link, topology, architecture and color analyses. The color analysis can produce root morphology as a function of color. It can also be used as a color area meter. WinRHIZO Arabidopsis has all features of the Pro version plus the ability to separate and analyse separately individual objects such as seedlings and leaves. It can do multiple root analyses per analysed image or regions of it.
