(which comes from SEED and NEEDLE to design both) automatically analyses seeds or needles much more precisely than conventional camera or conveyor based area meters.

is an image analysis system for wood cell anatomical structure measurement. 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. It is an alternative to wood density analysis done using x-rays.

is a generic Color Area Meter that quantifies area occupied by colors of interest (soil cover, disease quantification), classifies objects in function of color (pass/fail, healthy/diseased), measures basic object’s morphology (area, length, width..), do Color indexes and NDVI analysis (vegetation healthy/stressed) and can be used as a color or grey levels profilometer (to analyse their variations along paths). It can be calibrated to produce measurements in absolute reflectance values. WinCAM NDVI’s applications are numerous. It is very sensitive and can detect and quantify very small color differences.

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). The background can also be installed on a base with a camera holder arm which allows to position a camera over it. To facilitate this task, we offer the Leaf image Acquisition Kit for digital cameras. Precautions must be taken so that calibration can be done accurately and rapidly.

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.
