WinFOLIA, a versatile leaf area meter. Build your own system

Conventional and inexpensive digital cameras1 can also be used for leaf image acquisition (in the field or laboratory). Precautions must be taken so that calibration can be done accurately and rapidly. To facilitate this task, we offer the Leaf image Acquisition Kit (LAK) for digital cameras. It is made of a plastic background and a translucent anti-reflective fold-up cover that presses the leaves against it to hold them flat. The background can be placed on soil or held in arms for non destructive acquisitions (leaf still on the plant). The background can also be installed on a base with a camera holder arm which allows to position a camera over it. With this setup it is easier to get the desired field of view and to maintain a constant distance between the camera and the leaves. When this condition is met, the same calibration can be used to analyse a series of images.

1 Almost any model can be used. We do not sell or recommend digital cameras

Image Analysis Systems and Software for tree-ring, wood cell, root, seed, needle, broad leaf and canopy analysis and measurement

Is a generic Color Area Meter that quantifies area occupied by colors of interest, classifies objects in function of color, measures basic object’s morphology, do Color indexes and NDVI analysis and can be used as a color or grey levels profilometer. It can measure cell's walls and lumen (cell, vessel, parenchyma) area, length, width, number, density, position and more on images covering part of an annual ring or a few complete rings.

WinDENDRO, an image analysis system for tree-ring measurement, stem and wood density analysis

Productivity gain, operator comfort, images archiving with or without their analysis, a working method that encourages and facilitates verifications and easy commands to move back and forth along an analysed sample (without mechanical delays or backlash). In comparison to manual measurement systems, WinDENDRO offers advantages from different points of view.

Scanopy, an advanced canopy analysis system for scientific research

WinSCANOPY is a digital image analyser for canopy and solar radiations analysis which measures leaf area index, gap fraction, canopy openness, site factors and much more. It works from hemispherical images taken by a digital camera and a fisheye lens or from cover images with a narrower view angle. Some models are ultra compact and lightweight but still exhibit a very good image quality.
